Is a single neuron conscious? A brief discussion.

M. Advaita Vedanta’s perspective is better seen from the top down rather than from the bottom up. Consciousness or awareness can be considered (there is a consensus on this) as a ‘fundamental ‘property’ of (or pointer to) reality’, not reality itself, which is unfathomable and indescribable. It permeates every apparently external phenomenon, which is thus an expression or manifestation of Consciousness. Accordingly, a neuron, an electron, is a manifestation of Consciousness – ‘the One without a second’. Alternately, neurons, atoms, etc. are embedded in Consciousness or reality.

PB. I think the best words you can use to characterize reality are awareness/consciousness, existence/beingness and bliss/love. However, I wouldn’t identify reality with consciousness, the other two concepts, or all three together. They are just the purest manifestations of reality that we can identify. True reality is not a thing or concept, it is beyond definition.

But yes, I would agree that neurons, electrons etc. are phenomena of consciousness, as are these words and the bodies and minds that write them.

M. Metaphysical truth is sometimes called apperception, or direct supramental perception, and it is non-transferable. Nicholas of Cusa put it this way: “The highest wisdom is this, to know… how that which is unattainable may be reached or attained unattainably”. Metaphysics (philosophia prima, or first philosophy of medieval times) is not science, and its truths are often dressed as paradoxes, analogies, and metaphors; they are not meant to convince anyone who is not open to them.


A metaphysical truth appeals to intuition; it is an experience, or knowledge-experience… It is not speculation and is not amenable to subject-object relationship or distinction.

M. (to another participant) Did you look up the word ‘rishi/s’? It means ‘sage’ – Swami Vivekananda described Rishi-s  as Mantra-drashtas or “the seers of thought”. He told— “The truth came to the Rishis of India — the Mantra-drashtâs, the seers of thought — and will come to all Rishis in the future, not to talkers, not to book-swallowers, not to scholars, not to philologists, but to seers of thought.” (From Wikipedia).





samAdhi (part 1)

Experience versus knowledge – a brief look at samAdhi

I do not know an awful lot about neo-Vedanta. The term is generally applied to the teaching ‘introduced’ by Swami Vivekananda and carried on by the disciples of the Ramakrishna movement. There has been much written on this topic (which I have obviously not read!) and those who are interested will know that there are many contentious issues. Refer, for example to the book ‘Neo-Vedanta and Modernity’ by Bithika Mukerji, which may be read or downloaded at

However, one aspect that I am aware of is that neo-Vedanta claims that enlightenment is attained through the experience of nirvikalpa samAdhi. They also insist that Shankara himself stated this, whereas what I would call ‘traditional’ Advaitins believe that Shankara’s teaching was that it is self-ignorance that obscures our understanding of the truth and that only self-knowledge can remove it. Thus, one of the key issues around the topic of neo-Vedanta is that of experience versus knowledge. Accordingly, at the risk of inciting acrimonious discussions (!), I would like to look briefly at this assertion that samAdhi is a sine qua non for enlightenment. Continue reading
