REALITY-3


We can’t be the bodies; science has dismissed our body as illusions. We can’t be social creatures; society originates from us, not the other way around.

 The society has molded us into creature of social norms, it has utterly confused us and made us forget, why we are special. Its taken away the originality we were born with, and imprisonment us in a invisible trap, of social/cultural/religious dogmas.

We all go to the same schools and colleges, watch the same programs on television, aspire to similar idea of a good life. We all dress the same way; want the same cars, the same types of life partners. Ask any girl what do you look for in a guy, here is what you’ll hear. He should be honest, smart, successful/educated, open minded and should have a good sense of humor. Ask a guy what kind of girl he wants; she should be beautiful, modern, traditional, honest, caring and etc etc.

What are these? These are the stereotype of a perfect human being, preached by popular culture. These are labels, and our specie we love to put labels on everything. 
  
Hinduism and theology of many other religions have rightly identified that man is trapped and ruled by his vices. These vices alone stand in the way of liberation, true wisdom and self-realization.  These are mind or desire: kama (lust), krodha (anger), lobh (greed), moha (delusion), mada or ahankar (pride) and matsarya (jealousy).



The Trip - Is uncontrolled direction less rising and falling of thought, the movement of thought, latching from one thought/idea to another.



















Apart from very few exceptions of self realized beings. We are all tripping, with almost no control over it. Some of us realize that we are tripping. While others through no fault of their own, never realize this critical fact. No one ever told them. How do you find something that you aren’t even aware of? The reason being is lack of information, and being sucked into a consumerist world.

Realizing the trip is the first step. You can’t claim ignorance anymore. You have just been informed!


The Ego

 The ego is the identity you have created for yourself. A construct of the trips you have. It’s who you think you are. The role you play. Someone’s son or daughter, husband or wife, coo or manager in some company, etc.

An example-

We would all agree to the statement. “ I am not the same person, I was 5 years ago”

Think about that statement I am not the same person, I was 5 years ago. That’s a contradiction. Who was this “I” 5 years ago, and who is it now? Which one is really you? To both of them you refer as I, but there can’t be more than one I.

We would all agree that we are different people, in different situations. A different “I” when talking to your mother, A different ‘I’ when with girlfriends or boyfriends, different ‘I’ when with your friends, total different one when with enemies. Some times you are kind, sometimes rude, sometimes good and other times bad.

These are all the roles we play, shaped by our own beliefs and our understanding of what is acceptable or expected of us in each circumstance. Fueled by our need to be accepted, loved, respected or liked, etc etc. We play these different roles accordingly.

This role-playing, experiences/memories we have had in our life, over time gets forged into an identity. Who we think we are we. This identity we have created is the Ego.

If you are not the person, who you were 5 years ago or 1 day ago and you are not going to be the same person you currently are, 5 years from now.

Then who are you really? Who is this ‘I’, you keep referring to?

In the simplest words possible, you are the ‘I am-ness’. You are that sense of “I-ness”. That feeling of being. Spirituality refers to this as the Atman/Soul/Spirit/Consciousness.


Consciousness- is simply the feeling of “I am ness”, that you have.
Consciousness is awareness. We know a dog has consciousness. So does a bird. Maybe even bacteria being aware of temperature, chemicals or food. Maybe, even a rock has some sense awareness of its position or movement when being thrown.

But where we differ is self- awareness. Being aware of your own selves. That’s what makes us special. This is where we get the concept ‘I’. A dog doesn’t have this sense of I; he does think oh I am hungry or angry. There is just hunger.  This self-awareness is the reason why we can do all the amazing and complex task. Contemplate the entire universe or our selves.

Self-awareness is kind of double-edged sword. A great boon and a curse. It gives us our concept of ‘I’, which leads us into duality. This where the thoughts, trips, the ego, culture, art, war, feeling, thoughts stems from.

Duality

What is Duality?

Duality is the state or quality of being two or in two parts. Duality is inter-related polar opposites.

I’ll give you examples of how duality arises. When ever we make any statement. We create duality, for example. If I say I’m a tall guy, by that statement I have created a polar opposite. Compared to you there must be guys who are short.

If there is good, in relation to it, bad automatically exists.

If cold, then hot. If beautiful, then ugly. If right, then wrong.

When we say that I am a man or human. We create our polar opposite, as god or the universe.

Similarly the sense of self-awareness creates duality automatically. It divides the universe into the self (the body) and the non-self (external world). Our senses give rise to duality. To view the world, we must have a fixed point of view. From where we perceive it. This automatically leads to duality, between from where we look and what we look at.
We cannot escape this duality physically.

But we can escape it intellectually, by studying ourselves (through introspection/meditation) science and spirituality.

NON-DUALITY

Non-Duality is ancient school of thought (approx. 6000 years old). It is not a religion. It emphasizes the importance of Self-Inquiry and pursuit of the truth. Its core belief is

“Atman is Brahman” – The Upanishads

Atman (The Self, Soul, Spirit, Consciousness identified with body)
Brahman (Universe, Supreme Spirit, Consciousness as a whole)

Ramana Maharishi used to paraphrase, the Upanishads (Advaita Vedanta) and say.
After knowing that by which you know this (world, Phenomenon) turn the mind inward and then you will see clearly (i.e. realize) the effulgence of the Self.
That by which you recognize sound, taste, form and smell, know that as your Self, the Supreme Brahman (cosmic unity, Noumenon), the Lord of lords.”

This quote is saying, that its consciousness thru which we perceive the world, sounds, tastes, forms and smells, and this consciousness is what you are. Which is also the entire universe and phenomenon.

This is a non-dualistic understanding. Accepting this intellectual is the first step in non-duality. Which will give rise to an understanding, beyond the concepts. Once this happens you will be at peace inside.

I know what you are thinking. How can I be the universe? You say that because you understand and see the world in duality. Of good and bad, right and wrong, beautiful and ugly, God and Man.

 All there is, Is consciousness.” - Ramesh Balsekar

Consciousness is called “the Atman” when referred to a person. Consciousness is called the “The Brahman” when referred to the universe.


“The indivisible supreme self, is none other than you.”- Ramana Maharishi paraphrasing the Bhagavad-Gita.

Why is non- duality required?

Without this understanding our lives are meaningless wondering/seeking, filled with suffering.

The mistake we make is to identifying our self, with the perceived identity (the ego). The ego is nothing more than a role-playing, some play socially appropriate role. They crave approve of others. Some play rebellious role. They crave attention, by challenging the norms.

Why do we do this?

“Desire is the root of all human suffering.”- Buddha

We want/desire to be happy, we want pleasure. To be happy we need social status, money, popularity, love, sex, a certain job, a certain house, a certain title, etc etc.

Happiness comes from within, and not from material possession or social validity of your self.

It is ignorance, a myth created by society and media, to sell us all their products. Bushmen living in the jungles in Africa, are much more happier than us. And yet they have nothing, compared to us. Apart from one little under-rated thing called “Acceptance”.

Unless you have acceptance of “what is, as it is” you can never have happiness. Acceptance of the fact, that you have no control.

You think you have control, yet you can’t even control the thoughts in your head. Can you control, not feeling anger, hate, love, or sorrow? Control is an illusion you have, created by the ego.

All our problems have a common orgin. It’s the ego. You can be the ego all your life and never live a single moment.  Because rather than being present in each moment, and living life as it comes. We ponder what was, what will be, fearing, hoping. We waste our present.


I


This time the ego has ruined the present, by being fixated in the past.

The ego is always worrying about the past or the future. Because it believes is has control. Ego is the “THINKING MIND”. Thinking mind has no benefits, all it does is take you away from the present, feeding on all the vices. It can destroy us from within. Sadly this is what is going on within people all day.

The past is gone. It exist no where but in our minds, it affects nothing but our minds. If we would just let it go, it would be gone. And we would be free of it. But we carry the excess baggage from the past, which ruins our present. It’s same with the worrying about the future.

Not all thinking is bad. You can’t understand this, without thinking. For example If you need to drive to a different city, you need to think, which road to take, what time to leave, etc. You need to think to achieve this, thinking of the last time you drove there. This sort of thinking is called theWorking Mind, the problem-solving mind. Working mind isn’t judgmental, its functional thing. It doesn’t care about the past or the future, success or failure.


Solution to all your problems.
You must kill the ego. And in doing so, you’ll remove the seed of duality. All that will be left behind, will be a Non-Dual (singular) understanding that will stretch from your Self/Consciousness/Atman and cover the Universe/Brahman/Non-local Consciousness.

“There is Nirvana, but no one in it” -Buddha

How can this be achieved?

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment”- Buddha

Science and Non-Duality are both very different ways of saying the same thing. Their paths head in different directions, seeking the truth and then converge on the same inescapable point. 

Fundamental Nature of Reality is Consciousness

 Two sides of the same coin- Non-Duality & Quantum Physics.

We are shaped by our thoughts; we become what we think. When the mind is pure, joy follows like a shadow that never leaves.”- Buddha

“The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.”- Einstein                                        




Settle for nothing less, but the truth. Be in the Present, continuously moving forward in time.

“Strive on, diligently!”- Buddha’s last words before his death.

REALITY-2

Our understanding of the world as we see it, is based on Newtonian science. Newtonian Physics can only be applied to the scale that we can perceive. Like cars or planetary movements. It is a deterministic view, which is based on cause and effect. For example, the Newtonian idea was that, if we knew the variables of a system. We then could with a very high degree of precision, predicts the outcomes of that system. We know this is to be not true today.  This view is about 280 years old, needless to say completely outdated. I hate to sound like I’m beating up Newtonian ideas, its not intended. Newton was a pioneer at his time, a great scientist, and his work laid the groundwork for modern science to flourish upon.

The new/current theory is called “Quantum mechanics” is non-deterministic view of the universe. Most of us have heard about it, but know almost nothing about it. This is an attempt to explain the fundamental of Quantum Mechanics (QM) and its far-reaching implications for us.

 
Facts: Matter
1.    The idea of matter/atom put forward by Rutherford and Bohr, (what we learnt in school) was that the atom looks like a mini solar system, sun being the nucleus (protons and neutrons) where most of the mass is situated, around it are revolving electrons. This idea is more than a hundred years old, is known to be incorrect.
Matter/atom has been found to be 99.99999% percent empty space. Which means the difference between a dense heavy metal and empty space is off .000001 percent! What seems to be solid matter, is energy vibrating at a certain level.
Einstein said, “CIt has been estimated that the entire matter making up planet earth, can fit into a matchbox, once the empty space is removed. A picture/model can’t describe an atom; Hence quantum description of an atom is mathematical.
                         
                               Characteristics of matter are:
A)   An electron can exist in two or more places at the same time and then disappear all together. This experiment has been repeated 1000 of times with the same results all around the world. This phenomenon is called super positioning.
B)   Electrons don’t flow fixed paths or revolve around the nucleus of an atom. They seem to jump from one location to another without travelling the distance between, known as aquantum leap! Which is same as a person being in one corner of a room and a fraction of second later in opposite corner. Without actually travelling the distance between. Electrons only exist as a cloud of probabilities. Popping in and out existence randomly. There are numerous theory suggesting, different explanations to this, for example a leading belief is that electrons exist on many different dimensions and keep jumping between these dimensions. But we simply don’t know.
C)  Wave-particle duality: - atomic particles like electrons, even atoms and something even as big as molecules behave both like a wave and a particle. For example Person A throws a ball to person B. The ball first travels like a particle or object, then as a wave (like in an ocean) or both as a wave and a particle simultaneously. Depending on whether they are being observed or not.
A……. ))))))))))))……..B   and   A.).).).).).).).).) B
Those of you how cant accept these fact YouTube “the double slit experiment”. It is said that matter exists only in a waveform, only when it is measured or observed by an observer (us), it appears as particle.

D) The exact position and the speed of an electron, can never be known at the same time. We can measure the speed or its location but not both. This isn’t due to not having the correct measurement tools. But is rather the fundamental nature of a particle. It exists only as cloud of possibilities (wave particle duality). This is known as themeasurement problem in QM.

F) Quantum Entanglement- is a phenomenon where 2 particles interact with each other and become entangled. Meaning they start copying and acting like each other. The bizarre thing about quantum entanglement is that once entangled no matter how far these become from each other, they are always a mirror image of each other. For example if 2 cricket balls became entangled, then become separated, one is sitting in a field in England, the other one in India, involved in a T20 match. The ball sitting in England would start to mimic the action of the ball being played with. Without any stimulation the ball would race to the boundary, bowl itself, spin, swing itself. It doesn’t matter how far the balls become from each other they will remain entangled.  Einstein called this spooky action at a distance, as it amazed him.

2.    Light- what we call light is actually, Electro-Magnetic Radiation (EMR). It made up of tiny little packets of energy called photons. Light also exhibits dualistic nature. It travels both like a wave and particle. Speed of light is constant, always measured to be 300000 km/sec. Speed of light is universal speed limit, meaning nothing can ever exceed the speed of light. Because as any object approaches the speed of light, space and time would stretch enough to make sure it could never equal 300000 km/sec. (speed=distance/time; as speed goes up, distance would stretch or time would speed up, to protect the speed of light limit).

It is also worth noting that to an observers experience the speed of light, traveling at 3,00,000km/sec. But for light, the point of emission (A) and point of absorption (B), are co-incidental. What this means is that from lights point of view neither time nor distance exist, both time taken and distance travelled are “Always Zero”(Zero interval). Another way of looking the speed of light; is that an observer stretches this Zero Interval into 3,00,000 km for every second of time. Speed of light is actually the constant ratio of manifestation, perceived from our view. For every second of time, 3,00,000 km exist. But in reality neither time nor space exists. Meaning the entire universe has no size at all, it only looks to be astronomically large.

                             GENERAL RELATIVITY

Universe- A collection of trillions of galaxies (each with trillions of stars), separate by vast amounts of seemingly empty space. Just to give you an idea about the size of the observable universe (it might be far larger) is 93 billion light years across. Meaning to get from one end to another we would have to travel for 93,00,00,00,000 years at the speed of 3,00,000 km/sec or in kilometers= 93,00,00,00,000 x (300000 x 60 x 60 x 24 x 365) (you can try and calculate that, good luck!).

 Composition of the universe: 70 percent of the entire universe is made of dark energy, 25 percent of dark matter and the rest 5 percent is ordinary matter like us and our planet. This has been a well-known fact for 2 decades now.  


A.   Space is perhaps one the most important and the most misinterpreted/misunderstood concept. In Newtonian physics Space was believed to be empty and static with nothing in it to be described. It has been found to be not so empty and static. We all think of space as something that surrounds our planet. But since matter is 99.99999% empty “SPACE”, space exists everywhere, even within us and we are floating in it. It is fair to say therefore that we are made up of space rather than matter.  Far from being empty, space is teeming with energy, dark energy and dark matter.  Einstein description (best one we have) of Space is that it is 3 dimensional, and behaves like a stretchy fabric, that has inherent springiness, which is manipulated by matter and light. Or if you prefer the poetic Vedic description better of it being an enormous cosmic ocean.
B.   Time- The fourth dimension as described by Einstein. Time is perhaps the most complicated concept. Due to its complexity I cannot explain it, so you will have to study it yourself if you really want to know. Entropy gives rise to time. Time is also relative, meaning it can slow down and run faster. For example if you lived on the moon, time would run faster for you, than someone living on planet earth due to higher mass of planet earth. This is called time dilation. Time is relative, can be manipulated by light and mass.
C.   Space-Time Continuum- A concept described by A. Einstein with his theory of relativity. Which in simple language means the combination of Space and Time is relative, and not fixed. That matter and light both stretch and contract space-time.  For example it is incorrect to say that earth revolves around the sun. The mass of the sun actually bends space-time around it, while earth is simply trying to move in a straight line, but is trapped in the space warped by the sun. Analogy of a whirlpool with sun being the center and earth being sucked in each time its revolves around it.


Here is a picture of earth warping the space around it and the moon trapped in the wrap.  What we think and experience as gravity is just matter falling thru the wrap in space-time.  It is important to note that this picture is for demonstrations only, it depicts the earth sitting on space but in reality the space would envelope the earth from all direction.  

Picture-1

D.    Dark energy and Dark matter- these are the most recently made discoveries (1990). Nothing is currently known about dark matter, which is 25% of the universe. It’s called dark matter, as it neither emits or absorbs light, light simply passes right thru it, hence “dark” matter. Not much is known about dark energy either, what we do know is makes up 75% of the universe. Dark energy is present in space, which is why space is not considered empty anymore. Dark energy is what gives space its springiness. It is the weakest energy in the universe however due to it being presence in astronomical number, it becomes the most powerful source of energy. Here are 2 scenarios to explain the importance of it. Dark energy is fundamental for the universe to exist, as it does today. For example if dark energy was any weaker than its present state, gravity (warping of space-time by matter) would have pulled and fuse together all the matter in the universe. This is called the big crunch. Nothing but a large clump of matter would exist, with no space even within it. On the other hand if dark energy was even a fraction stronger than its present strength it would make space expand so much that each and every atom/particle in the universe, would be ripped apart to its fundamental components and be pushed away for eternity. And nothing would exist, the universe would be dark and cold place. Which is believed to be our current case, meaning that with time dark energy will become stronger and stronger and eventually rip everything apart (the big rip).




ΓΌ  Light also has a wave particle duality. From the point of view of light/science, neither time nor space exists.


ΓΌ  We learnt dark energy is 70 Percent of the universe and present everywhere in the universe(within space), in every single atom and even within in Sub-particles. 


When viewed through the understanding of Quantum Physics and mathematics universe, is a system in FLUX. This is an Artistic representation of the flux by a Japanese painter.




It’s a view of the universe, which is indivisible or Non-dual. It is a complex system, interconnected, full of different forms of energy acting upon each other, which gives rise to pattern and complexity. Universe is fractal in nature, and is far too complex for human intellect to contemplate. We are part of this non-dual universe, and not separate beings with bodies like we think.

In conventional thinking, we always view the universe/space as something external, that which exists outside our atmosphere. We view our planet/world as being separate from it. These divisions are just concepts, we have created. In reality all there exists is the flux.

So what does all of this information leave us with, and what does it mean for us. It dismisses everything we are aware of our senses, bodies, matter, time and space. So what is left? We can dismiss everything, but one thing we cannot dismiss is consciousness. What is meant by that is, we can dismiss matter as being unreal/illusionary, but our experience of it, cannot be dismissed.

What is this consciousness, which the quantum physics, refers to as an observer? An observer who can change, the states of matter by a simply looking and stretch the zero interval into a diverse universe 93 billion light years across. Science has no answer for this question, yet it has led us here. Since there is no way for science to examine, measure, analysis consciousness/awareness. It has hit a dead end. Which makes sense, as science is a product of consciousness.



REALITY



The problem with Newtonian era science is that it put the entire world into nice little labeled compartments as observed. And dismissed anything that didn’t fit into those compartments as being an isolated anomaly caused by something external; however with the advancements in science and technology. Led to emergence of Quantum physics, through which we now see Nature of Reality, in a different light. Where anomalies aren’t dismissed, and the universe is looked upon as one complex system.

If Quantum Physics is to be believed, which it must be. Taking into consideration the thousands of experiments conducted over the last 70 years that validated it. The picture it paints is a very weird one, something that seems to make no sense and is counter-intuitive.

While we see the world as being logical; seamless; solid; based on action and reaction, Nature of Reality is anything but!

Our senses are very useful, they help us to navigate and interact with the world. We humans perceive the world through our senses, these senses have been the only way we could ever experience the world. However useful our senses fail completely, when we start asking the fundamental questions regarding the nature of reality.

We have no notion of anything else existing, especially since we have never been told not to trust our senses. Why wouldn’t we trust our senses? It’s the only way we can perceive.  

The world as it appears to be through our senses Vs. The world as it is.

The world we see, feel, hear, touch, smell is a figment of our imagination. The real world doesn’t look or behave in the way; we experience it through our senses.

It is very important to note that our brains are incredibly powerful, and can create things that don’t really exist.

An example would be a person with a psychological disorder that has an illusionary friend. He can talk to, hear and touch his friend like he can with any other normal person. How can this be? How can an illusion be touched? Well if you realize that it’s the mind that touches and not the hand. It can be!

Psychology, Neurology and philosophy have known about this for a very long time, that it is the brain that sees and not the eyes. What this means is the fact that all our experiences—all our perceptions, sensations, dreams, thoughts and feelings—are forms appearing in consciousness (our mind). When we dream, we can see things, but our eyes are closed. It’s the mind that sees.

When I see a tree it seems as if I am seeing the tree directly, but science tells us something completely different is happening. Light entering the eye triggers chemical reactions in the retina; this produces electro-chemical impulses, which travel along the optical nerve to the brain. The brain analyses the data it receives, and then creates its own picture of what it thinks is out there. I then have the experience of seeing a tree. It is very important to note that, what I am actually experiencing is not the tree itself, only the image that appears in the mind, as I perceive it to be. We have no idea what the tree in reality looks like.

It also interesting to note, that it takes the brain about 1/10 of second to process this data. Meaning instead of seeing a live feed, what I am really seeing is a recorded video, playing in my mind. This is true of everything I experience. Everything we know and perceive. Every color, sound, sensation, every thought and every feeling, is a form appearing in the mind (consciousness).

Neurons are nerve cells. Each of our brains has billions of neurons, which are inter-connected with each other, to form a Neuro-net. Its how all the information in our brains is connected and structured. This is what it would look like magnified.





As powerful as our brains are there is a limit, to how information we can process in each second. To overcome this limitation, an editing center was required, so that the important information can be filtered out. Over millions of years of evolution; our brains have come up with an editing center called Reticular Activating System (RAS). Where our sub-conscious mind edits all incoming sensory information (vision, hearing, touch, taste, smell) according to what it perceives to be important and noteworthy. Whatever sensory information it believes to be important, is passed to the conscious mind. What ever it believes to be not important is edited and not experienced consciously. On an average a human takes in 2 billion bits of information, but can only process 2,000 bits. That’s means we are only aware .0000001 percent of all the incoming data. Reticular Activating System (RAS) of the brain is responsible for what is included in this .0000001. Just imagine what we are missing out on, due to this processing limit and filtering process.

This is why our senses can’t be relied upon to accurately understand the world, which the entire 100 percent.

For example you are driving and see 200 people standing at a bus stop, among them is beautiful woman, your brain quickly scans this data, the beautiful woman is flagged and experienced by our conscious mind. At the end of day you’ll remember is the beautiful woman, while the199 people will be filtered. The good news is that RAS is reprogrammable, through neural plasticity.

Also known as neuroplasticity, is the changing of the structure, function and organization of neurons, or nerve cells, in response to new experiences. It specifically refers to strengthening or weakening nerve connections or adding new nerve cells based on outside stimuli. It is responsible for all learning.

 The golden rule by which Neuro-plasticity works is neurons that fire together wire together. More they fire together, stronger the connections get.  
While Neuro-nets that don’t fire eventual grow weaker and die.




Neuro-plasticity is at work every second, with each thought, our brains are rewiring and creating new pathways. What ever we pay attention to, whatever we want/desire, think about gets programmed into the RAS, through neuro-plasticity.

Once we are aware of neuro-plasticity, we can employ it. By controlling our emotions and thoughts we can re-wire our brains completely. The brain doesn’t differentiate between good or bad. What ever you do, it will re-wire to get better at. And change who we are. The more you do it, the better you get!

So pay attention to what goes on inside our head. Just imagine what we can achieve when we think the right thoughts based on the right understanding. Sky is the limit!


Vision
Next we must realize that our eyes can only see what we call the visible spectrum of light, which is tiny portion of the entire spectrum of light. We see the world full of colors, but in reality colors don’t exist. What we see as colors, are different wavelengths of visible light. When light of certain wavelength hits the retina in our eyes, cells that are sensitive to that specific wavelength send a message to the brain. The brain then interprets these different wavelengths as different colors.

If we could see the rest of the spectrum, the world would look completely different than it looks in visible light! Even just adding either x-ray or ultraviolent spectrum would completely alter our view. Our bodies and things that we think as solids would become see through.



We cannot only see light, but also can feel light. When we step into the sun, we can instantly feel the heat of sunlight. What we experience and think of as heat, is infrared light/thermal radiation. Similarly when we touch another person, and feel their warmth what we experience as warmth, is the thermal radiation being emitted from their body. Yes, all matter can emit and absorb light. Including us humans, we are emitting light just like the sun/ light bulb. Here is what I look like when viewed from a thermal/infrared camera. 

Blue means cool, green cooler, red is warm/ hot. As you can see the world and people would look completely different, if we could view in infrared spectrum.



Hearing

Similarly the ears can only hear, 20 Hz and 20 kHz, hence most of the sounds that go into our ears, aren’t even registered. Next time you hear nothing and your dog goes crazy it could be due to the ultrasonic waves that we are unable to hear. If we could hear the subsonic frequency, we could hear the earth constantly humming at 7.83 Hz. It is estimated that about 2 percent of the population can hear this hum, due to defects in ears, especially in old age.


While you are sitting and reading this, you can feel the chair/bed/ground. It appears to be solid to us. But is it?                             
The solidity of matter is an illusion; there is nothing solid about it. In fact it has been proven that physical matter is 99.999999% empty space!
I know what you guys are thinking, how can this be? “I can feel the chair I’m sitting on and the ground beneath my feet.” “I can touch and feel the textures.” I don’t doubt that you can’t feel it, I feel it too. I doubt what is it “that” we are actually feeling.
Here is thought experiment to better illustrate what I mean.
“Imagine a visit to a science city. One of the rooms there has powerful magnets all over the floor, with south pole (or negative charge) facing up. There are also special boots with magnetic soles that have South Pole facing down.
Now a volunteer is first blind folded and then asked to put on the special magnetic boots. He is then send on a walk in the room, as he walks into the room the south pole of the shoes and south pole of the floor start repelling each other. To everyone looking through the window this person would appear to be walk on thin air. But the blindfolded person with the magnetic boots, when asked would say that he has been walking on either a normal floor or feels a cushiony carpet floor.”
What this person is feeling beneath his feet is the magnetic repulsion, and experiences this repulsion as a solid.
 Anyone who has ever played with magnets is aware of this force.
Believe it or not but this actually what is happening when we are walking around. 

So how & why do we get the experience of touching a solid object - when there is nothing solid about matter itself?
The whole experience of the solidity of matter arises from the mutual repulsion of negatively charged electron fields.” 

What this means is that, nothing ever touches anything, right now while you’re sitting in your chair/bed, you are actually hovering over it. Just as in the thought experiment. The electrons (negatively charged particles) in your body and the electrons in your bed are both pushing away/repelling against each other. This repulsive electron field is what gives us the experience/sensation of touch a solid. 
What we are feeling/touching/rubbing against isn’t really what we think it is. We can never really touch anything, just glide over other matter. If this repulsive electron field was some how removed we would just fall through the entire planet and drift into space.

When we add all of these facts up, we realize what we believe to be reality is just a delusion. An incomplete picture! There much more going on than what “appears to be” through our sense.

You may question why should you care and how does this apply/relate to you. What was the point of you knowing all of this?

What is more important that which appear to be or that which is?

The mistake we make is to assume that what we see/experience is real. We suffer a delusion when we believe the images in our minds are the external world. We deceive ourselves when we think that the tree we see is the tree itself. The tree itself is a physical object, made of physical matter—molecules, atoms, sub-atomic particles. But from what is the image in the mind constructed? Clearly it is not constructed from matter. A perceptual image is made up of the same "stuff" as our dreams, thoughts, and feelings; it is made up of consciousness!
I can go on and on about this, and dismiss each of our sense. However I am sure you get the idea.

If you want to learn more about “what is”, as oppose to “what appears to be”. You need to rely on unbiased data from science, and its implication. Introspect within your self. There is much to learn from science and spirituality, it will shock and amaze you. Science and spirituality are both saying the same thing, in their own unique ways.
