I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness.
– Max Planck

(X): Non-dualism is not something that can be understood in any formulation of words, and at best one can approach it conceptually only perhaps by means of negation, meaning by specifying what it is not.

A1. All doctrines and teachings are necessarily couched in language, which is a system of symbols. All concepts are just pointers (e.g. ‘pointing at the moon’), including those of Nonduality (ND). So it is not only negation — I think you will agree. I also referred myself to superimposition followed by rescission as a method of gradual understanding taught in Advaita Vedanta. The final end is doing away with language once final understanding has been reached, that is, once there are no further doubts or questions.

Language and Color

Those people who regularly read my articles will know that, although my educational background is that of a scientist, I frequently criticize science in respect of its inability to say anything useful about the nature of reality. Because science can only operate by virtue of a subject making observations on an object, it only has validity in the empirical realm (vyavahAra). Nevertheless, I do acknowledge that science can sometimes throw light upon the thorny topics that we frequently encounter in advaita.  An obvious example of this is the findings of Benjamin Libet and Daniel Wegner regarding free will, about which I have written several times. Accordingly, I was very interested to hear recently (on a BBC Horizon program about how we perceive color) that scientists have carried out experiments which demonstrate that language affects the way in which we see the world.

I did not expect to see anything relating to advaita in the program but, when they described an experiment concerning the Himba tribe of northern Namibia, it quickly became clear that this was relevant to the vAchArambhaNa sutras from the Chandogya Upanishad.

The brain and consciousness

Original questioner, a Doctor, training in psychiatry: What does the brain do after we die, how long does it stay conscious?

A (Marcus Geduld, Shakespearean director, computer programmer, teacher, writer, likes dinosaurs.) Answered Nov 24, 2014 : Nothing happens to it. It’s dead. ‘Switched off.’ That’s basically the definition of death—when your brain totally stops functioning. This question is kind of like asking how long a radio keeps on playing when it’s switched off.

If we consider humans as finite beings, what evidence do we have that “eternity” actually exists?

Physical bodies are finite, corruptible, but are human beings just their bodies (and their finite minds)? There is a mysterious, undefinable, and unmeasurable entity called consciousness which appears to pervade all sentient beings and nature in general. Nature, all life, is conscious – dare we say? This entity – consciousness – is undeniable, for it is our most direct and unfalsifiable experience. Consciousness – by consensus of a majority of physicists – escapes all parameters of physics, neurophysiology, and brain studies. But not only consciousness, but so-called matter is also in the same category of the intrinsically unknowable, even if there are methods for measuring and experimenting with such entity as matter-energy.

Again, no one knows what eternity might be, such are the limitations of our means of understanding reality, even though physics and mathematics come to our aid in this and also with the phenomenon of space (space-time). What is more, philosophy and metaphysics have a better grasp of the extra-physical dimensions of reality aided and abetted as they are by (universal) intuition. For metaphysics time does not exist outside of our minds, and, rather than eternity-(duration), timelessness – or what is the same, that only the PRESENT exists – is what, as a concept, gives a semblance of reality to reality (all that is and ever has been) – incomprehensible to the unaided mind.

Q.490 Consciousness and the Brain

Q: My question is one I can’t seem to clarify through any book, teacher or teaching:

How do we know that the brain isn’t responsible for consciousness? While we can observe mind with all of it’s contents as objects and then say we cannot be that which we observe, how can we be sure that there is not just some part of the brain which does the observing that is giving us this ability to watch thought? How does Vedanta address this? How can we know that the brain isn’t simply the one observing all phenomena?

Side note: I lost consciousness once due to a fall and blacked out, and all I can say is that there was complete absence of being and no one there to be aware of the non-beingness. No observer nor observed. Beyond no-thing. Absolutely no experience beyond the concept of the word. Continue reading

Consciousness – Not such a Hard Problem (2 of 2)

Read Part 1

Without Consciousness, nothing can be known. But Consciousness itself cannot be an object of knowledge, just as in a totally dark room, a torch may illuminate everything but itself. Knowing requires both knower and known. For Consciousness to be known, it would have to be a knowable object but it is the knowing subject. We ‘know’ Consciousness because we are Consciousness. Consciousness is our true nature. The ultimate observer (which is who you essentially are) is simply not amenable to any type of objective investigation: who could there be beyond the ultimate observer to do the investigating?

Numerous attempts have been made to define Consciousness. Most seem to revolve around the assumption that a person’s behaviour indicates its presence or absence. It is argued that consciousness is present during the waking and dream states but not in deep-sleep or under anaesthesia, for example. But this is again to confuse Consciousness and awareness. When we awake from a deep-sleep, we are able to state with confidence that we were ‘aware of nothing’. This is a positive statement – there were no gross objects, emotions or thoughts present for us to perceive. Continue reading

Consciousness – Not such a Hard Problem (1 of 2)

This is an article I wrote for a Philosophy magazine 5 years ago but it was not published. It was included in my book ‘Western Philosophy Made Easy’, which was based upon the 18-part ‘Overview of Western Philosophy‘.


The studies by neuroscience into the functioning of the brain will tell us nothing about Consciousness. We must differentiate between Consciousness and awareness. Consciousness enables the brain to perceive just as electricity enables the computer to process data. The computer does not generate electricity; the brain does not produce Consciousness.


Ever since the ‘study’ of consciousness began to be an academically acceptable area of research amongst scientists, both they and Western philosophers have been heading deeper and deeper into a conceptual cul-de-sac. At the root of the problem is the tacit assumption that science will (one day) be able to provide an explanation for everything. But, more specifically as regards this particular issue, the big ‘C’ of Consciousness must be differentiated from the little ‘a’ of awareness. The conflation of the two means that the true nature of Consciousness will forever elude them.

Below, I address some of the various misconceptions that are misleading many of the neuroscientists and philosophers in the field of Consciousness Studies. It is accepted that not all of these investigators will hold such ‘extreme’ positions (and a few are much more liberal in their approach). Continue reading

Debate with a crypto-buddhist

‘How many of you agree with the theory that our consciousness ends when we die?’

A commentator: (There’s of course nothing called ‘Soul’ of a person that goes on to live forever in afterlife. I’m an atheist. I person believe that when we die, our brain and the entire body shuts down, and we meet an end. Those of us who experienced anesthesia knows how it feels when our brains are inactive.)

M. I for one do not agree. Bodies decay and die not so consciousness. The whole is greater than the part, and that whole can be called ‘life’, ‘existence’, or ‘consciousness’ – none of it reducible to the physical or material. All bipolar concepts, such as life-death, good-bad, one-many, mind-body, ‘you and I’ (‘me and the other’) are false in themselves– just concepts. There is only totality (‘what is’), namely, existence or being – not many existences (existents), but one existence; not many loves, but one Love . And all of us are in essence, that is, in reality, existence and love – they are not ‘two’ (love being Plato’s ‘higher Eros’ or desire) once plurality is ‘seen’ for what it is: a deception or narrow vision.

Q. 444 Prior to Consciousness

Q: 1. Is there or could there be an Absolute Nothingness that everything, including Awareness, comes from or out of? Part of this question is the possibility that Awareness or Consciousness is only in this world and for this experience.

2. Without a brain and nervous system, or a manifesting medium, Awareness doesn’t even know it is. Therefore, it is still temporary, or a state it seems? And, as Nisargadatta says, what we are is PRIOR to this.

A: 1. The confusion of ‘awareness’ versus ‘consciousness’ a la Nisargadatta has been addressed in other questions. ‘Awareness’ in traditional (my) terminology is a characteristic of the mind of a jIva. A sharp, controlled mind has more awareness than a dull, undisciplined one. But ‘awareness’ is not a ‘substance’ in its own right, so it cannot ‘come out of’ anything. And ‘absolute nothingness’ is just that – and nothing can come out of it by definition! (Or, perhaps more accurately, ONLY nothingness can come out of it!) The concept of ‘absolute nothingness being the reality’ is shunya vAda, which is a Buddhist idea refuted by Shankara in his brahmasUtra and mANDUkya upaniShad commentaries. Continue reading

Q.438 Could a computer become enlightened?

Q: Will an ‘upload’ be capable of giving mokSha to a computer? By ‘upload’ I am referring to the Science Fiction concept of scanning the contents of a human brain down to the quantum level, and then simulating that complex entity in a virtual environment. Ray Kurzweil is a key proponent who claims this will be possible sometime within the next few decades.

A: The mind is rather more than just data, and more than processing-software running on brain hardware. Although all these things are ultimately Consciousness alone, there has to be something there to reflect the light of Consciousness in order for a thing actually to become conscious. And it has to do this very well indeed before it can become self-conscious. And it has to do it brilliantly in order to gain mokSha! I don’t think uploads satisfy these criteria!

Q: I agree with your answer, but I suppose the answer will depend largely on the assumptions one makes in thinking through the problem. Can reflected consciousness arise in a silicon-based entity? Or only carbon-based creatures like ourselves? It’s actually a pretty stimulating question, and it touches on the ‘hard problem’ as defined by David Chalmers, etc. If you ever do get around to reading his book, he has an interesting thought experiment on the principle of organizational invariance, where neurons are one-by-one replaced with silicon equivalents. At what point does consciousness (which here would only be reflected) disappear in this process? Not asking for an answer from you – just wanted to mention this aspect of the question.

A: You are still assuming that consciousness relates to the gross body – replacing carbon with silicon. The mind is the subtle body in Advaita. Having said that, I see no reason why there should not be silicon-based life forms associated with subtle bodies elsewhere in the universe…

Q: Good point, thanks. It makes me wonder though, if the mind is the subtle body and doesn’t relate to the gross body/brain, then why is the subtle body affected at all when the brain becomes physically damaged? I was thinking in terms of reflected consciousness arising in the ‘mirror’ that consisted of gross + subtle body.

A: Good point, too. I guess the metaphor of computers does come into play here, the mind needing the hardware of the brain in order to manifest (better word than function, since it retains the autonomy of the subtle body, which is supposed to migrate to a new body after the death of the existing one).
