Is a single neuron conscious? (From Quora)

 A short 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 a pointer to) reality’, not reality itself, which is unfathomable and indescribable. Consciousness permeates every apparently external – and also every internal – 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.

Q. 482 What happens after videha mukti?

Q: When the jIva removes the ignorance of his real nature, and realizes Atman is his Real unchanging Self, if the body dissolves, what happens afterwards?

If there is no further birth, do we then remain as Absolute, without name and form, without knowing anything other than pure Self? Is it like space all being uniform without any form? Is there nothing that is known? Surely it doesn’t remain In an absolute ‘stateless state’ of no Knowing?

A: There have been a couple of questions around this before – see http://www.advaita.org.uk/discourses/q_and_a/q_and_a44.htm#q263 for example.

Your question is based on a misunderstanding. At the empirical level, there is indeed a ‘person’ who may or may not become enlightened. If he/she does gain Self-knowledge, then clearly the outlook of the person for the remainder of his/her ‘life’ is going to be different.

5.  Discriminating the Self (Atma) from the not-Self (anAtma):

That which cannot perceive, but can become an object of perception is anAtma (not-Self). For example, our body is inert. It has no sense of “I am.” It cannot perceive anything. But our consciousness can perceive the body. Just as we perceive body and mind, we also perceive joys and sorrow, likes and dislikes.  The polar pairs of opposites like joy and sorrow, are also a result of our ignorance. Consciousness Itself is untouched by them.

Consciousness alone is Atma. Everything else in the world is insentient. Not only inanimate objects such as chairs and tables, but also our bodies, life-force, and senses are insentient. Movement does not imply sentience. Wind moves, but wind is insentient. The air around us, the light that travels through space, and the five fundamental elements are insentient. Only Awareness that can feel “I AM” is sentient. Every object is known to our Awareness, but no object is aware of its own being-ness. A tiny spark of Awareness that is aware of all the objects is within every one of us. It is the Inner-Self (pratyagAtma). Continue reading

4.  Ignorance is Indeterminate:

Ignorance is like a gossamer sheath that covers up and conceals our true Knowledge. An analogy may help. Think of a muslin cloth in which a few pieces of asafetida are kept wrapped in. The smell of asafetida lingers on the cloth even after the asafetida is consumed and the cloth is washed. Like the persisting smell on the cloth, impressions from the past experiences get stored in the causal body. Just like the smell of the asafetida that cannot be gotten rid of easily, the clinging impressions on the causal body too are difficult to be eliminated.  These lingering traces of the effects of past actions are called the vAsanA-s. They get expressed as the desires in the mind, and also as the individual’s likes and dislikes, proclivities, etc.

The Yoga system of Patanjali says that the causal body must be controlled so that the machinations of the vAsanA-s could be neutralized.  Shankara advises us that the causal body must be completely annihilated because suppression and control give scope for violent return of the vAsanA-s. He says that it must be completely melted away leaving no trace of the vAsanA-s so that desires do not sprout up in the mind. This process of dissolving the causal body is called pravilApana.

The Ignorance that Isn’t – 1/8

1.  Introduction:

We are all familiar with our gross physical body. It is available to our direct perception and it gives us our ID. Vedanta tells us that we are blessed with two more bodies — the subtle body comprising life-force, the mind and the intellect, and a totally imperceptible third body, subtler than the subtle body. It is called the causal body, the source of the other two bodies. Advaita Vedanta avers, as we all know, that what we truly are is Pure Consciousness. Consciousness is our nature. It is the very Self that knows “I AM.” It is not that the Self possesses Consciousness. Self is Consciousness. We are actually none of these bodies.

But for some unknown and indeterminate reason, the Self, instead of being the Subject, the Knower or the Seer, got contaminated. We superimposed the Self with the known and the seen, the objects.  We shifted our ID from being the Self to being a body – mostly as the gross physical body, and sometimes as the subtle body. That is a great fall for the Self – from Self to not-Self because the bodies are insentient (anAtma). The strong association we experience with the three bodies stands as a proof of the apparent fall. The severity of the fall could have been far less had we considered the bodies to be “mine” instead of taking them to be “me,” identifying ourselves with them as “I am my body.” Continue reading

AbhAsa vAda

This is effectively Part 6 1/2 of 10 in the pratibandha series. It follows on from the heading of “The ‘mixture of Atman and mind’”. Apologies for the misleading and changing part numbers. This is the result of writing ‘as I go’ rather than completing the entire topic first.

xi) AbhAsa vAda

This theory was mentioned briefly above in 2b, when bhAmatI and vivaraNa were discussed in the context of sources for mistaken views of Advaita. AbhAsa translates as ‘fallacious appearance’ and it is effectively the term that is used to describe this ‘mixture’ of Consciousness and intellect. Shankara addresses this in his upadesha sAhasrI, principally in chapter 18 ‘tat tvam asi’. The following analysis is with the help of Ref. 211.

As the chapter heading indicates, the topic is the mahAvAkya and how the knowledge of its truth is all that we need in order to gain enlightenment. We are already free and always have been, so once we realize this, there is nothing more that needs to be done. The idea that, after gaining ‘merely intellectual knowledge’ from shravaNa, we have somehow to gain ‘direct experience’ of Brahman before we are liberated, is called prasa~NkhyAna vAda. This is discussed and rejected in detail below, under the topic of ‘meditation’ but in this chapter Shankara introduces an objector who has these notions and the subsequent arguments are relevant to this topic of pratibandha-s.

Post-Shankara contributions to the concept

(I am indebted to Ref. 195 for many of the scriptural citations in this section.)

It is certainly true that there are few references to the word pratibandha in prasthAna traya and Shankara bhAShya, although a number of discussions can be interpreted as referring to the concept. One can certainly argue that the idea of jIvanmukti itself strongly implies that of pratibandha-s. Being ‘in a body’ is clearly a limitation compared to not being so constrained. Indeed, having a body to begin with is said to be the result of ignorance, so the fact that there is still one present implies that there must be some aspect of ignorance still present.

Accordingly, whether or not you accept the idea of prArabdha karma being the reason for the j~nAnI continuing to inhabit a body, it seems that ‘freedom’ cannot be total until the body drops. It is therefore reasonable to think that this body-mind might be susceptible to ‘obstructions’ of various types, while this embodiment continues. The body has needs, after all, and even though there is no longer any identification with the body post-enlightenment, the mind is still very likely to be affected. And the j~nAnI still continues to utilize the Atman-animated-buddhi, as described above.  I.e. pratibandha-s are implicit in the differentiation between jIvanmukti and videha mukti.  Continue reading

The ‘mixture of Atman and mind’

While the body-mind remains alive (i.e. continues to be animated by Consciousness), the person is a mixture, as it were, of both. If I am enlightened, I know that I am really the original Consciousness, Brahman, but I cannot escape the fact that I am also still a jIvAtman, with that same Consciousness reflecting in the intellect. If I am unenlightened, I either do not know about paramAtman or do not believe that this is who I really am. Instead, I identify with body, mind, attributes or functions. I mistakenly superimpose (adhyAsa) the properties of the mithyA body-mind onto the paramAtman.

The same applies even to ‘knowing’. When we say ‘I know’, whether or not we are enlightened, it has to be the reflected ‘I’ that is speaking. Shankara says in his bhAShya on Bhagavad Gita 2.21:

“ …the Self, though verily immutable, is imagined through ignorance to be the perceiver of objects like sound etc. presented by the intellect etc.; in this very way, the Self, which in reality is immutable, is said to be the ‘knower’ because of Its association with the knowledge of the distinction between the Self and non-Self, which (knowledge) is a modification of the intellect and is unreal by nature.” (Ref. 6)

Thus, it can be seen, that this provides an explanation for the fact that I may be enlightened and yet the mind can still be affected by pratibandha-s. It there are none, because the mind was purified prior to enlightenment, then I am a jIvanmukta, enjoying all of the benefits of a mind unsullied by negative emotions. Otherwise, I must continue to perform those sAdhana-s that will eliminate such tendencies before I can reap the ‘fruits’ of enlightenment, j~nAna phalam. Whilst both are still inevitably a ‘mixture’, the one with pratibandha-s still says ‘I’ with a significant element of jIvAtman; the one who has purified the mind says ‘I’ with a predominant element of paramAtman.

Debate with a crypto-buddhist – 6

S. Almost every Buddhist school recognizes Madhyamika as important teaching, but it is almost always subordinate to the direct teaching of the Buddha or the teacher you study with. Every Buddhist school is also in debate with other Buddhist schools. Theravada/Mahayana, Vajrayana/Dzogchen, Dzogchen/Mahamudra, Nichiren/Zen, etc. It is mostly academics that engage in these debates which never solve a thing. A real teacher will never involve you in comparative mind. They always show you the recognition of your nature which is never seen as a ‘thing’ and never separate from any ‘thing’. They leave philosophy behind. This is not to say that philosophy cannot inspire.

The tendency in all of us to want to believe in something lasting, all-knowing, and final, must be regarded in the same light as our learned beliefs that we acquire from our conditioning and cultures. The idea of racism, that one color, nationality, or faith is superior to another, for example, is embedded in all cultures. Through our ordinary minds, we can work this out to the point of disbelief, or even disappearance from our thoughts and feelings that will allow us to treat each other with respect and dignity.

In the same fashion, we can look at ideas and concepts of philosophical and religious meaning and believe that these hold truths and even ‘take refuge’ in them. These conditioned ideas get reinforced through group belief, authoritative declarations, and our grasping desire to find some lasting truth in something that we can experience or know. We never really grasp what these teachings are talking about except in our conditioned mind, our ability to retain and repeat, and believe. Continue reading

vij~nAna

Shankara differentiates what might be called ‘ordinary’ or ‘intellectual’ knowledge (j~nAna) from ‘transformative’ knowledge (vij~nAna). The knowledge becomes transforming – i.e. making it efficacious in conveying the status of jIvanmukti – when the gaining of it has been preceded by successful sAdhana chatuShTaya sampatti. In his bhAShya on muNDaka upaniShad 2.2.8, he says:

“Wise, discriminatory people (dhIrA) see through vij~nAna; vij~nAna is a special (vishihtena) knowledge (j~nAna), born out of the teaching of shAstra and AchArya (shAstra AchArya upadesha janitam), and received in a specially prepared mind, born (udbhutena) out of total detachment (vairAgya), having control of inner and outer organs (shama and dama), and which is therefore capable of upAsanA to begin with and later of nididhyAsana which together are called meditation (dhyAna). Through such a vij~nAna, wise people realize that the nature of the Atman (Atmatatvam) is non-different from the nature of Brahman (brahmatatvam)…” (Ref. 10)

‘Who am I?’ in communication

Who are we speaking of when we use the words ‘I’ and ‘you’ in writing and speech?

Since we are Advaitins, there are actually three possibilities:

  1. ‘I’ could mean Atman/Brahman, if used from the ‘as if’ pAramArthika viewpoint;
  2. ‘I’ could mean the reflected Consciousness (chidAbhAsa);
  3. ‘I’ could mean the usually understood ‘named person’.
