Traditional Teaching and Deep Sleep – III. mAyA & Creation

Part – I              Part – II              Part – III

[The latter part of the article requires a bit of mathematical (or at least arithmetic) orientation in the reader. If you know the addition, 1 + 1, that is enough. Otherwise, it could prove slightly boring!]

We shall tackle now the question of how we wake up to be what (we think) we were before we went to bed.

I said in my previous argument that our waking up to a new morning and into an awake state is comparable to another cycle of creation.  So I suggest we examine how creation itself takes place.

From a scientific perspective, creation seems to be happening from ‘nothingness’ and dissolving back into nothing.  Vedantins prefer to call nothingness as ‘Beingness’ simply because even ‘nothingness’ has to ‘Be.’

If we go by what Quantum Physics tells us, what we may refer to as ‘nothingness’ is not just emptiness.  There is an enormous amount of energy in ‘Emptiness.’ Physicists have been able to measure this energy of empty space.

The energy within the empty space of the nucleus of an atom is the main reason for the weight of the nucleus (and hence of the matter we are all).  The energy of the emptiness within the intergalactic space is the reason for the expanding universe causing the colossal and mighty galaxies to recede from one another at speeds exceeding the speed of light. This vast energy is the result of constant creation and annihilation of virtual particles smaller than sub-atomic particles. Thus creation-dissolution is an ongoing unstoppable roiling and boiling process from emptiness to emptiness within emptiness!

Traditional Teaching and Deep Sleep – II. Dreams

Posted on by

[The topic of Dreams is something I have not originally planned to include here in this series which was primarily designed to address the issue of Upanishadic support for considering deep sleep itself as Liberation (moksha).]

Part I      Part – II            Part – III

Please allow me here to take a short digression to discuss dreams because of a few questions raised by our esteemed readers.

Secrets of Sleeping Brain - Architecture of Sleep - Prof. M Walker, 2009

Fig. 1. Sleep Hypnogram (After M. Walker, 2009) – Click on the figure for enlarged view.

First of all, I would like to correct the misconception that some of us have that the moment we hit the pillow and get lost in sleep, we just flow through one continuous phase of dreaming, then deep sleep and, lo  behold, we get up refreshed in the morning. So, to this extent, the sequence of Awake state (A), Dream state (U), and  Deep sleep (M) corresponding to AUM as presented by Mandukya  Upanishad is awfully way out. ***  The Upanishad says that these three states arise in an everlasting turIya which is compared to the ‘silence’ at the end of AUM. ***  Several experimental studies carried out over a period of more than half a century demonstrate that the architecture of our sleep pattern is vastly different as experienced by us every night. A typical hypnogram (the nightly sleep cycle) we go through each night is shown in Fig. 1. (Please click on the figure for an enlarged view).

Traditional Teaching and Deep Sleep – I

Part – I        Part – II          Part – III 

In my Talk on “Inquiry in Science and Vedanta “, the slides numbered 50 and 51 are about  the three states of  consciousness — Awake, Dream and Deep Sleep. (The full PowerPoint Presentation can be viewed at : http://beyond-advaita.blogspot.in/ ). The three worlds are represented by the three distinct circles I, II and III and a ‘Me’ is shown by the circle IV in the Slide 50 (Fig. 1 below). In our normal understanding, we think that “I am a separate ‘self’ (individual) and I pass through three distinct worlds viz. the Wakeful world, the Dream world and the Deep Sleep world.” We also take that the worlds to be external to ‘me.’

Fig 1: The Normal Worldview – an individual “I” (IV) passes through three distinct worlds (I, II, III) that are external to ‘me’ during a day of 24 hrs.

Non-dual Reality – Q. 328

Posted on by

Q: Can one ever KNOW that reality is non-dual?

A (Ramesam):

(i)   YES, The moment you can grasp tight your reflection in the mirror!!! 
(ii)  No, you cannot know it like you know the salary you get.

(iii) Yes, you cannot ever NOT know it; what all IS, is your perception alone.
(iv)  No, if you place yourself aloof trying to know it as a distant object.

(v)  Yes, you know It in your deep sleep.
(vi)  No, if you want to measure and compare to duality. Continue reading →

brahman and AkAsha – Q. 326

Posted on by

Q: My mind has this tendency of creating doubts every once in a while and I was able to find answers for every doubt I’ve had through contemplation, logic and reasoning. But not this one.

Before I begin, please understand that my mind simply will not accept anything that cannot be proven to it through logic and reasoning, which is why ‘Sruti says so’ has not satisfied my mind.

So, my question is, how can we say that Brahman is the cause of Akasha (I’m referring to the Vedic element which is the substratum of everything that exists) and not Akasha itself? How do we know that consciousness itself is simply not the Akasha our bodies are made of which happens to be a conscious entity?

I understand that reality is non-dual, but Akasha being omnipresent (basis of all things), omnipotent (since it is Akasha that takes all forms, it can be said to be the cause of everything), omniscient (if we cannot deduce that Akasha is an unconscious entity, it would become omniscient), infinite, eternal and able to take forms without changing its own nature makes it no different from what is described as Brahman.

Enjoying Being Brahman – Q. 324

Posted on by

Q1: When I was in the constant of awareness that I was Brahman I used to enjoy the Thoughts that all indeed was Brahman. Since I progressed to the simply I AM I am not enjoying the earlier feelings of thinking everything as Brahman. Is it that the state of being in simply I AM is absolute absence of any thought whatsoever? 

 Q2: How to overcome the sleep state to be in constant awareness of Who am I? Please some practical hints!

 Regarding my second point I intended to know more about the Fourth State in which the Saints wait to consume all their Prarabdha. How is this state practised and what are the skills of it?

Please shed some light on how do the realised but unpractised people live in their day to life while all the time immersed in their truest identity. My readings tell me just to let things happen without least botheration how they happen. Is it this way?

A (Peter): These questions make a strong case for why seeking proper guidance in this work is vital. Vedānta isn’t something that anyone can just pick up from a book, any more than anyone can dive straight into advanced mathematics from a book. If one doesn’t have a basic concept of numbers and the ways they combine through addition, multiplication, subtraction and division then how could one cope with the more esoteric realms of the subject? And compared to the science of self-knowledge, which is subtler than the subtlest, higher maths is crude. Self-knowledge needs appropriate prep work before the books make sense. Continue reading →

ANESTHESIA, DEEP SLEEP, DEATH AND CONSCIOUSNESS – Part 3/3

Posted on by

[Part 1/3         Part 2/3]

To eff the ineffable:

We travelled the depths of Non-duality in Part 2/3.

As Jeff would put it, “I am realized, you are not” is a silly game. There’s no one – none – that’s not Brahman. You are already realized! So relax.

And let’s know what the brainy brain-scientists say consciousness is.

What consciousness is and how the brain produces it (if it does), is still one of the great challenges to science. Until a few decades ago, science was averse to dabble into this subject for lack of adequate investigative tools (both conceptual and instrumental). “Today consciousness research has become a passion for many scientists.”

But what is consciousness? It’s like asking what life is or what energy is. You know it when you see it. We say that “a brain that is fully awake and constructing experiences is fully conscious.” The thalamus, a sort of hub located deep in the brain for information flows from the senses to the upper reaches of the brain is crucial for consciousness. A person turns into a vegetative state if the thalamus is damaged or the information flows are inhibited. This does not mean that thalamus produces consciousness; it may just show that one is conscious – much like a thermometer which doesn’t actually make the heat, but tells you how hot it is.

Dr.Giulio Tononi of the University of Wisconsin–Madison and his colleagues are studying

States of consciousness (After L. Saunders, 2012)

brains that are deeply asleep, under anesthesia or in comas to understand consciousness. As shown in the figure at the right, “awareness typically tracks with wakefulness — especially in normal states of consciousness. People in coma or under general anesthesia score low on both measures, appearing asleep with no signs of awareness. Sometimes, wakefulness and awareness become uncoupled, Continue reading →

ANESTHESIA, DEEP SLEEP, DEATH AND CONSCIOUSNESS – Part 2/3

Posted on by

[Part 1/3      Part 3/3]

Before going into a consideration of Deep Sleep, once again a small detour.

Dennis raised in an e-mail the question of Sleepwalking. Where would it fit in the Model?

Some people amble around in sleep and even hurt themselves.  A few persons could commit heinous crimes in the state of somnambulism.  A well-known case is that of Kenneth Park in 1987 when he strangulated his father-in-law and killed his mother-in-law. However, he was let out by the court on the ground that he was sleepwalking when he harmed and killed people.  A similar case of acquittal also occurred in 1846. Apparently the body of the sleepwalkers is active but the mind seems to be asleep.

Neuroscientifically speaking, in the case of sleepwalking, the motor cortex of the brain is functional whereas the frontal lobe vested with executive functions is at rest. This means that a part of the mind (that propels the body to act) is active while the part responsible for reasoning and self-control is asleep. Continue reading →

ANESTHESIA, DEEP SLEEP, DEATH AND CONSCIOUSNESS – Part 1/3

Posted on by

Recently there was an interesting question about the disappearance of ‘me’ when a patient is administered anesthesia in preparation for a major surgery.  It is quite intriguing where the missing ‘self’ has gone and when under anesthesia (Q. 313).

Peter, Sitara and Dennis answered the question very ably explaining the Vedantic philosophy behind the various states of consciousness (as we usually understand the term).  The false concept of the sense of a separate ‘self’ we think we possess and the reality of an eternal Self; the misunderstanding that arises if we take the word Consciousness to mean the same in psychology (& medicine) and Advaita;  the possible existence of multiple ‘minds’ which derive their illumination from an unchanging, everlasting, self-effulgent One Brahman were dealt with by them. Hardly can anything be added to their clear exposition made from the stance of Non-duality beyond saying a word of our appreciation and gratefulness to them.

I would like to use this opportunity, if I may, to bring to the notice of a wider audience an approach I developed in 2004 relating the state of our alertness to our body-mind system in order to understand who we really are. We shall also in the process examine what are Deep Sleep and Death and what is the condition of the brain under different states, including awake, dream, deep sleep, death, coma, anesthesia etc.

Let me call this as “A Model for Nirvana.”
