A man must have not only faith, but intellectual faith too.

Introduction
Once St. Augustine was asked to define 'Time' and he replied, 'If you do not ask
me what time is, then I know. If asked, I know not!' He could very well have been
speaking of consciousness.i There are some things we cannot speak of, simply
because we do not know enough about them. And there are other things which
we feel we are very familiar with, and yet, when asked, we are entirely unable to
give a satisfactory account. To the latter category belong things like time, space,
matter, mind, love, self ... and consciousness. One reason why we find it so
difficult to adequately define them is that we formally define a concept with
concepts that are yet more fundamental, and when we come to the most
fundamental concepts of all (like time, space, matter, consciousness etc.) we are
page 1 of 19
left without the conceptual bricks with which to construct formal definitions. And
from a subjective point of view at least, what could be more fundamental than
consciousness itself? That is why it is so difficult to say what consciousness is
although it is the very warp and woof of all experience.
Perhaps it is this very difficulty in defining the field that has inhibited the
scientific study of consciousness till recent times. Interest in consciousness
studies has picked up considerable pace in the last quarter of the twentieth
century. And with this increasingly vigorous scientific investigation has come the
awareness that consciousness has been of abiding interest to the philosophies
and spiritual traditions of world civilizations since ancient times. Today
consciousness studies is truly mutlidisciplinary – brain science, computer
science, psychology, linguistics, philosophy and spirituality are all collaborating
in what may be the grandest and most fascinating quests that humanity has ever
engaged in – the quest for ourselves.
Each school of Indian philosophy, each darsana, has as its goal and raison d' etre
the attainment of release of the subject from worldly suffering, termed variously
as apavarga, kaivalya, nirvana, moksa. These schools are concerned with the
emancipation of the subject, and subjectivity being associated with
page 2 of 19
consciousness, consciousness becomes a fundamental concern for all these
schools. Or as Chakravarthi puts it, '... subjectivity requiring consciousness,
consciousness is an unavoidable factor in any soteriology.'iv
Further, many of these schools made knowledge an essential part of their project
of obtaining final release for the subject. Ignorance was regarded as the root
cause of bondage, and when knowledge removes ignorance, bondage is
destroyed. The relationship between knowledge and release then became
another issue of vital concern, and knowledge being inextricably linked with
consciousness, a theory of consciousness became an indispensable precursor to
epistemology. Even among schools as diverse as Nyaya realists and Yogacara
idealists, Samkhya dualism and Madhyamaka absolutism (nihilism?), we find a
common central concern – consciousness. But it is to Advaita Vedanta that we
must turn to find a philosophy of consciousness, par excellence.
The plan and purpose of this paper may be mentioned in brief. First, the central
philosophical problem in consciousness studies, the so called 'hard problem' will
be considered. Next, we shall review the fundamental tenets of Advaita Vedanta.
This will be done primarily by reading a key passage from the Brhadaranyaka
Upanishad with the commentary by Sankaracarya. Finally, we shall see if this
ancient philosophy of Advaita Vedanta can help us with the 'hard problem' of
modern consciousness studies.

The Hard Problem
page 4 of 19
Scientist Roger Penrose begins his well known book, The Emperor's New Mind,
with a little story. A child confronts a super 'intelligent' computer, touted to have
knowledge enough to answer all possible questions, with a very simple
question,'What is it like to be a computer?'. The computer founders, unable to
even comprehend the question, let alone answer it. Yet it is a question any
human, even a child, can understand easily. This story dramatically points to the
nature of the hard problem.
To understand the hard problem better we must first distinguish between two
components/aspects of conscious experience – the subjective feelings and the
objective features. The philosopher Thomas Nagel made this significant point in
his now famous paper, 'What is it like to be a bat?' Bats fly about with the help of
a sophisticated version of sonar – echo-location. Nagel asks - imagine if we were
bats - what would this experience be like? Would we hear many sounds echoing
from objects? Probably not. Just as our experience of vision is of objects and not
of light waves (though, technically, all that our eyes receive is light), bats would
presumably be aware of objects, not sounds. What this would be like is beyond
our imagination. The point is that it is impossible for human beings to grasp the
exact quality of bat-experience. There is something like 'being a bat' which no
amount of objective description or imaginative effort can quite recreate. All the
scientific knowledge about the physiology and neurology of bats cannot help us
experience 'being a bat'— the way a bat experiences it subjectively. Nagel's
thought experiment strongly argues against a strictly objective view of
consciousness.v
There is a gap between the descriptions of science and our personal experience.
The philosopher Joseph Levine calls this the 'explanatory gap'. According to
Benjamin Libet, ' There is an unexplained gap between the category of physical
phenomena and the category of subjective phenomena.' V R Ramachandran
page 5 of 19
author of the popular book, Phantoms in the Brain, says that,'... despite two
hundred years of research, the most basic questions about the human mind...
remain unanswered, as does the really big question, What is consciousness?' vi
Responses
It is worth noting here that Advaita Vedanta has sometimes been presented as an
ancient version of Berkeley's idealism. This is a misunderstanding of the Advaita
position. Advaita, in common with other Indian darsanas, considers mind to be
jada – insentient matter. In the empirical realm, the Advaita position is in fact
akin to realism rather than idealism. In fact, Sankaracarya is vigorous in his
critique of Vijnanavada, which takes a position very similar to Berkeley's
idealism.
In the twentieth century, the tide turned firmly against idealism. Advances in
science strengthened the explanatory power of the scientific materialist
page 6 of 19
paradigm. All our mental life and subjective experiences are identical with, or an
epiphenomenon of, the brain. There is no need to posit an entirely separate
special realm of mind/spirit/soul to explain consciousness. Consciousness is
simply a product of the changing states of the brain. Matter is the only reality,
consciousness can be reductively explained as a product of matter, science seems
to proclaim. This is a kind of monism – a materialistic monism, where matter is
the one and only reality. Many neuroscientists and philosophers expect advances
in brain science to ultimately explain how the brain can produce consciousness.
The major hurdle they have to confront is the hard problem.
We may add that the Advaita position has the added advantage (over scientific
materialistic monism) of offering a radical solution to the hard problem of
consciousness.
At the risk of oversimplification, one may thus summarise the present state of
affairs in consciousness studies – the scientific materialist seeks to explain
consciousness in terms of matter (brain states) but is unable explain subjective
experiences (the hard problem). Various dualist approaches seek to address the
hard problem by positing that consciousness is something special, irreducible to
brain states, and attributing subjective experiences to this special type of
page 7 of 19
phenomenon. But then they have to explain how this unique irreducible
consciousness can interact with matter, specifically, with the brain.
Consciousness studies seem to be caught between the Scylla of the hard problem
and the Charybdis of the mind-body interaction problem.
At this point, we shall turn to a very ancient text and try to understand the
profound philosophy that it propounds, with a view towards new answers to the
hard problem and the related mind-body interaction problem.
The king asks the sage the following question – 'What serves as light for a man?'
Yajnavalkya answers that the sun serves as light for all the activities of man.
When the sun sets, moonlight takes its places and serves man in all his activities.
Upon being pressed further, Yajnavalkya ventures that fire can serve as light
when there is no moonlight or sunlight. When the sunlight and the moonlight are
not there, and the light of the fire is absent, speech serves as the ‘light’ by which
man performs his activities. Finally, when the sunlight and the moonlight are not
there, fire is extinguished, and speech is hushed, what serves as the light? At this
point, Yajnavalkya answers that the Self of man serves as the light. Then arises
the question, ‘What is this Self?’—katama atmeti.

hrdyantarjyotih purusah;
sa samanah sannubhau lokavanusancarati, dhyayativa
lelayativa;
sa hi svapno bhutvemam lokamatikramati mrtyo rupani. (Brh.
Up. 4.3.7)
Here light (jyoti) means that which helps us to know something. Speech (or
sound) or odour, or indeed any sensory input can help us in knowing something
of the external world and so they qualify as 'light'. When all such external lights
are unavailable (and there is no external sensory input as in dreams or artificial
sensory deprivation environments), it is the consciousness of the Self (atmajyoti)
that is the only guide. Now Janaka's question Katama atma iti is an attempt to
locate this atmajyoti – which one of these – body, sense organs, organs of action,
mind, intellect – is the atmajyoti? The question is quite subtle. In each of the
earlier cases, the jyoti - sun, moon, fire and speech – was of the same nature as
the objects they revealed, i.e., all were jada – insentient, material. But this
atmajyoti is quite different from the objects it helps reveal. It is not material, it is
pure consciousness. This pure consciousness, which is the Self (Atman), is
reflected in the antahkarana (in the buddhi to be precise). What we experience
as consciousness in daily life, and what consciousness studies is actually
investigating, is this empirical consciousness. This empirical consciousness is
technically called chidabhasa, and is identified with the buddhi. This is the
jivatman, the individual who designates himself as 'I'. This 'I' then identifies
page 9 of 19
himself with the rest of the body-organ-mind complex. Sankaracarya comments,
The intellect, being transparent and next to the self, easily catches the
reflection of the light of the self (the pure consciousness). Therefore
even wise men happen to identify themselves with it first; next comes
the Manas, which catches the reflection of the self through the intellect;
then the organs, through contact with the Manas; and lastly the body,
through the organs. Thus the self successively illumines with its own
light the entire aggregate of body and organs. It is therefore that all
people identify themselves with the body and organs and their
modifications indefinitely according to their discrimination. ix
Now we see that the body, the external shape, has no light as its own
essence, is not self - luminous, and cannot know itself; neither can the
mind. Why not? Because the mind waxes and wanes, because it is
vigorous at one time and weak at another, because it can be acted upon
by anything and everything. Therefore the light which shines through
the mind is not its own. Whose is it then? It must belong to that which
page 10 of 19
has it as its own essence, and as such, can never decay or die, never
become stronger or weaker; it is self - luminous, it is luminosity itself. It
cannot be that the soul knows, it is knowledge. It cannot be that the
soul has existence, but it is existence. It cannot be that the soul is
happy, it is happiness itself. That which is happy has borrowed its
happiness; that which has knowledge has received its knowledge; and
that which has relative existence has only a reflected existence.
Wherever there are qualities these qualities have been reflected upon
the substance, but the soul has not knowledge, existence, and
blessedness as its qualities, they are the essence of the soul.x
The two terms dhyayativa lelayativa are crucial. Dhyayati iva means
The dream experience, svapnam, is entirely in the mind and the physical body
and external world of the waking state are not there. Consciousness transcends
the physical body, and it is the light which illumines dreams (since external lights
are not there). The term imam lokam, literally this world, refers to the body.
Several key features of the Advaita theory of consciousness emerge from this
text and its commentary. Pure consciousness is the Self and the Self is pure
consciousness. Consciousness is independent of the body and it transcends the
mind too. It gets identified with the body and mind and thereby, acts as if it is a
knower and doer.
page 11 of 19
Discriminating consciousness from the mind raises a new question—How is
empirical knowledge possible?
Pure consciousness is ever effulgent and never changing. Therefore all objects of
knowledge should always remain illumined! We should be able to know
everything all the time. But this is not how we have knowledge. Our knowledge is
episodic, always changing, and it is knowledge of specific objects, not of all
objects. How can Advaita explain this?
To answer this question, Advaita Vedanta introduces the concept of vritti jnana. A
vritti is a modification of the antahkarana, and the antahkarana is simply the
upadhi or limiting adjunct of the Atman. The vrittis have specific contents which
constitute the contents of our various knowledge episodes. The vritti is illumined
by the light of the chidabhasa, the empirical consciousness which pervades the
antahkarana (and which in turn is a reflection of pure consciousness in the
antahkarana), and this illumination of the vritti constitutes empirical knowledge
(vritti jnana). Pure consciousness itself is called swarupa jnana to distinguish it
from vritti jnana. Or, to put in other terms, the Self which is pure consciousness,
gets reflected in the mind (as chidabhasa) and illumines the modifications of the
mind and this is what constitutes empirical knowledge. The vrittis, modifications
of the mind, rise and subside but consciousness shines eternally illumining all
these knowledge episodes (or the lack of them, as in deep sleep). Regarding
consciousness and empirical knowledge, Sanakaracarya says, 'There are two
visions, one eternal and invisible and the other transitory and visible ...Through
that unfailing eternal vision, which is identical with It and is called the self-
effulgent light, the Self always sees the other, transitory vision in the dream and
waking states, as idea and perception respectively, and becomes the seer of
sight....'xi

The theory of consciousness advanced here has a distinct advantage in that it
longer has to contend with the mind-body interaction problem. Mind
(antahkarana) is held to be a form of matter; subtle matter, but matter
nevertheless. Hence, mind can influence the body and vice versa. Both being
matter, there can be no objection in principle.
While this is a step forward, it creates a new problem too. The antahkarana is
matter, how can it interact with consciousness which is so very different from it?
The standard answer is that the antahkarana can reflect consciousness because
it has a predominance of sattwa guna which makes it pure and superfine. But
this won’t do – because sattwa guna, no matter how pure and fine, is still matter.
According to the Advaita's own doctrines, Atman is the true subject, chit, eternal,
unchanging and all pervasive, while the antahkarana is objective, jada, ever
changing and limited in space and time. How could two such diametrically
opposite entities interact in any way? A material mirror can reflect material light
– but how can a material antahkarana even reflect the immaterial Atman?
This Samkhya theory has one advantage over the traditional Western
notion of soul(mind). There is no split between the body and the soul
(mind), in so far as the soul (mind) is the Inner Sense
(antahkarana)....But if there was no split between body and soul (mind),
there was the idea of another split which proved much more fatal than
the differentiation of body and soul (mind) has ever been... The Vedanta
page 13 of 19
theory of the self is greatly indebted to the Samkhya.xii
(Words in italics have been inserted in the text above to link it to terms
used in the present discourse)
Sankaracarya makes this problem the linchpin of Advaita. He begins his principal
work, the Brahma Sutra bhashya, with a statement which is a philosophical tour
de force in itself:
It being an established fact that the object (matter) and the subject
(consciousness), that are... by nature as contradictory as light and
page 14 of 19
darkness, cannot logically have any identity... the superimposition of
matter and its attributes on consciousness... should be impossible.xiv
From the concept of superimposition the Advaitin derives this corollary – that
which is superimposed must be false, the ground of superimposition must be
real. Body-mind and the whole external world are mithya while Atman (Brahman)
alone is real – Brahma satyam, jagat mithya. The term Advaita, non-dualism, is
now justified since there is no second reality besides consciousness. Or, to put it
differently, the two - the world (jagat) and the individual (jiva) have no existence
apart from Consciousness – hence Advaita, 'not-two-ism'. The true nature of the
jiva and jagat is Brahman. We are that Brahman, each one of us. This is
expressed by the famous Vedantic mahavakya Tat Tvam Asi (That Thou Art).
This would translate into our discourse as - consciousness is the sole reality,
page 15 of 19
matter (the whole material universe not excluding our bodies, life and even mind
which is subtle matter) is a superimposition. That which is superimposed is false.
Hence the whole panoply of matter is false – it has no reality apart from the
ground of superimposition, consciousness itself. A radical unity (identity to be
precise) between the universe, the individual and consciousness is discovered.
And this is what Advaita calls God. '...we find that the idea of God in the Advaita
is this Oneness'xv
Now we see how this world view can lead to a way out of the consciousness-
matter deadlock. Consciousness itself projects matter, matter evolves into
worlds, bodies and finally, minds which can reflect consciousness (which is then
experienced as empirical consciousness, chidabhasa). And these minds (and
organs, bodies and the external universe) are superimposed upon consciousness.
The empirical consciousness with its superimposed adjuncts (mind, sense
organs) gets empirical knowledge of the world and feels itself to be a knower
(jnata), an agent (karta) and enjoyer (bhokta). The subjective aspect of
experience which brain science is unable to pin down and which is the main
stumbling block to scientific materialistic monism, is due to consciousness itself,
the atmajyoti Yajnavalkya speaks of, whose very nature it is to subjectively
illumine everything. The highly problematic interaction of the subjective and
objective, though not explained or accounted for by the theory of adhyasa,
superimposition, is seen in an entirely new perspective in which consciousness is
put at the centre stage as the one and only absolute reality.
Swami Vivekananda narrated the following anecdote during one of his lectures in
London.
page 16 of 19
I remember a story told by Prof. Max Muller in one of his books, an old
Greek story, of how a Brahmin visited Socrates in Athens. The Brahmin
asked, "What is the highest knowledge?" And Socrates answered, "To
know man is the end and aim of all knowledge." "But how can you know
man without knowing God?" replied the Brahmin.xvi
Replace man with 'empirical consciousness' and God with 'pure consciousness'
and the point of the anecdote (as well as this paper) becomes obvious.
The problem of consciousness studies at the present juncture is that it does not
seem to recognize the possibility of pure consciousness. It is interested in the
consciousness manifestation in daily transactions – empirical consciousness.
Since this empirical consciousness is a reflection of pure consciousness in the
Advaitic parlance, we cannot formulate a satisfactory theory of consciousness if
we limit ourselves to empirical consciousness and discount the very possibility of
pure consciousness. By admitting pure consciousness, a powerful solution to the
intractable hard problem of consciousness may perhaps be found, the Gordian
knot could finally be untied.
I may make bold to say that the only religion which agrees with, and
even goes a little further than modern researches, both on physical and
moral lines is the Advaita, and that is why it appeals to modern
scientists so much. They find that the old dualistic theories are not
enough for them, do not satisfy their necessities. A man must have not
only faith, but intellectual faith too. --- Swami
