Advaitic sages Sri, Sankara and Goudpada declared the non-dualistic truth as ultimate truth or Brahman is rational truth and scientific truth.

 Modern science leads in the end to the discovery that the world is the mind and that causality is non existent. Gaudapada and Sankara made precisely the same discovery, because they had the spirit of science, the desire for ascertaining facts and being sages of the highest order, saw the truth.

As one digs into the annals of the history of India  one becomes aware of the fact that, Science was pursued in ancient India but only the philosophical aspect of it, which examined the matter and ultimately found it to be idea, which thrust aside personal predilection in its investigation. India however ignored the practical aspect of science and was not interested in the applications of science: hence India was backward in applied science but far ahead of west  in pure scientific method. For 2000 years India has been a slave nation which has lost even this scientific knowledge which it once possessed as it has lost its philosophy of truth. Today the gate to Advaita must be modern science and nothing else. 

The Hindu theory that the mind actually travels to an object is absurd. Why does the mind get a different and a more correct impression as it approaches nearer to a hill. Why did not the mind, if it traveled, bring a correct report at the very first. Mandukya unpunished  has rejected this theory, which is unscientific.  Scientific fact about visual sensation is correct so far as it says the optic nerve communicates its vibration to the brain. But how does the brain transmit it to the mind? Here all is theory and confusion.

The same truths which modern science gives can be found in  the declaration of  the  Sage, Sri Sankara and Gaudapada. But  the Advaitic sages kept their supreme states of steady wisdom a secret.  

Advaitic Sage, Sri, Sankara' gave religious, ritual or dogmatic instruction to the mass but pure philosophy only to the few who could rise to it. Hence the interpretation of his writings by commentators is often confusing because they mix up the two viewpoints. Thus they may assert that ritual is a means of realizing Brahman, which is absurd. 

In the commentary to "Brahma Sutras Sri, Sankara writes:- " "The highest beatitude is not to be attained by Yoga." (Sacred Books of East Series page 298 Vol.1.)   And he also says Samadhi is the same as sleep (p.312).

 ---This indicates that yoga is not the means to self realization.  And yogic Samadhi is not non dual wisdom. 

Thoughts and thinker are nothing to do with the formless witness. The witness is that witnesses the thoughts and thinker together and remains always in the within the waking or dream as their formless substance.

People think that, more they think, the more they will get; but it is really an error. It remains only a thought and gives them back only thoughts.  Anything seen, observed, cannot be the Self or the Witness. 

Consciousness (soul) is the substance and the witness of the duality.  The duality is present in the form of mind. The mind is present in the form of the universe. The universe appears as waking or dream and diapers as deep sleep. The one which is aware of the coming and going of the three states is neither the waking entity nor the dream entity but the formless soul, which is present in the form of consciousness.  When the soul becomes aware of its formless non-dual true nature in the midst of duality it is called self –awareness. It is foolish to limit the consciousness only to duality because the consciousness pervades all the three states

The earliest ancient sages used the word ‘I’ to the witness of the three states not to the ego as moderns use it and think the ‘I’ without the body is the  self. The seeker has to understand the fact ‘I’ is not the self but the witness of the ‘I’ is the true self, which is eternal. 

People think that the ‘soul’ or ‘spirit’ is something different from the mind. They believe that the mind is really two. This is the confusion among religionists and intellectuals. If ‘Soul’ has any meaning, if ‘spirit’ has any meaning, so long as one thinks of them, they are merely ideas. No, Mind is the highest: it is consciousness, non-dual wisdom.

The individual is a bundle of memories, desires within the waking or dream. The memories and desires are part of the duality. Therefore the individual self is entirely part and parcel of the mirage. Peoples' ideas of that they will go to some world after death, some astral plane or religious heavens will disappear as nonsense with the disappearance of belief in the reality of the ‘I’.  

Sage Sri, Sankara says: one must first know what is before him. If he cannot know that, what else can he know or understand? If he gives up the external world in his inquiry, he cannot get the whole truth.

VC 63. Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

Even  "Jesus said:-"Those who seek should not stop seeking until they find. When they find, they will be disturbed. When they are disturbed, they will marvel, and will reign over all." (Gospel of Thomas 2)

"The Kingdom of God is inside you and all around you, Not in a mansion of wood and stone.  Split a piece of wood and God is there, Lift a stone and you will find God." (Gospel of Thomas)

When the seeker indulges in deeper self-search becomes aware of the fact that, the experience of birth, life, death and the world are mere illusion created out of spirit (consciousness), which is the innermost self.

Thus Advaitic sages Sri, Sankara and Goudpada declared the non-dualistic truth as ultimate truth or Brahman is rational truth and  scientific truth.       

The Atman is the witness-consciousness that experiences the action, the actor, and the world of separate things.

The Atman is the witness-consciousness that experiences the action, the actor, and the world of separate things. It is like a light that illuminates everything in a theatre, revealing the master of ceremonies, the guests, and the dancers with complete impartiality. Even when they all depart, the light shines to reveal their absence.

The formless soul or consciousness is the innermost self. The soul or consciousness is self-illumined. So how can the body which is inert (insentient) and illumined by an external agent be the consciousness, which is present only within the waking or dream?

The consciousness (soul) the innermost self is apart from the three states and permanent, as it endures even after the death of the body and world   within the waking or dream.

Even the subtle body consists of many parts and is unstable. It is also an object of perception, is changeable, limited and non-existent by nature. So how can this be the true self, when the body exists only within the duality(universe)?

The immutable soul, the substratum of the ego, is thus different from these two bodies, and is the true self, the consciousness, the formless witness of the three states; and it is present in everything and everywhere in all the three states  and yet transcends them all.

Thus the enunciation of the difference between the soul and the body has (indirectly) asserted, indeed, after the manner of the inquiry, analysis and reasoning, the reality of the three states. The birth, life, death and the world are part of the duality (universe). The consciousness, which is the true self and it, is the formless witness of the birth, life, death and the world.

Thus the view that the body is the true self has been denounced by the enunciation of the difference between the soul and the body. The seeking mind has to grasp the truth, between the three states and the formless witness (the soul).

It is the Self that is in illusion and it is the self that gets free from the bondage of the illusion. The illusion is present in the form of mind. Mind is in the form of universe. Universe appears as waking or dream and disappears as deep sleep.  The individual experiences of birth, life, death and the world are within the waking experience.  The dream is parallel waking experience and waking is parallel dream.  

Deeper self-search reveals the fact that the, self is neither the waking entity nor the self is the dream entity but the self is formless soul, which witnesses the coming and going of the three states in succession without the physical apparatus.  This has to be mentally grasped and assimilated to realize the formless soul, the innermost   self is nothing to do with the three states. On the standpoint of the three states, the three states are mere illusion. 

The practical life within the practical world, which is present as waking experience, is mere illusion. If waking experience is mere illusion than the individual experience of birth, life, death and world are mere illusion.   If the experience birth, life death and the world are mere illusion, it means the form; time and space are mere illusion.  If form, time and space are mere illusion, it means the past, present and future is mere illusion. Thus it is necessary for the seeker to realize the fact that,   form, time and space are one in essence, in order to realize the three states are one in essence. That essence is consciousness. Thus all the diversity is created out of   formless consciousness. Thus no second thing exist other than consciousness, the innermost self. Seeker of truth has to constantly reflect on the subject in order to get firm conviction of the truth.  Seeker has to reflect on the same truth again and again until it becomes reality. One needs to constant reflect on the subject until he gets firm conviction of what is what.

As person perceiving the world one is unaware of , because he thinks his body as body, his ego as ego his experience of the ,world as world but never he is unaware of the truth they are just mirage created out consciousness due to ignorance of the truth .

As person perceiving the world   one  is unaware of , because he thinks his  body as body, his  ego as ego his experience of the ,world as world but never he is unaware of the truth they are just mirage created out consciousness due to ignorance of the truth . 

Words are needed until one gets firm conviction of ‘what is what. People need reading and hearing the words to think deeply and reach the ultimate end. 

People fail to understand that, the emptiness is the nature of the self, which is consciousness.  When self becomes aware of its formless non-dual nature it becomes empty of ignorance or illusion or duality or experience of waking or dream.  Thus whatever remains empty of duality or ignorance or illusion is non-dual reality. Only through wisdom one becomes aware of the truth in the midst of duality.

That is why Sage Sri, Sankara said: 63_(VC)- Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation.

The universe will not remain as reality when wisdom dawns. Universe is mere mirage created out of consciousness and there is unity in diversity because there is no second thing exist other than consciousness.

One thinks he is imprisoned within this body; whereas the body and his experience of the world are within the mind. The consciousness is hidden within the three states but it is without the three states.  The one, which has the awareness of the three states, is not the body but the soul, which is in the form of consciousness. Thus consciousness is not limited to waking experience alone because it pervades all the three states. Till one views and judges the world-view on base of ego he is in the grip of individuality or intellectuality.  The self is not an individual because it is universal. And it pervades in everything and everywhere in all the three states. Thus individualized judgment will not lead one non-dual destination.  

 That is why Sage Sri, Sankara says in (VC)-65:-  As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments.

66. Therefore the wise should, as in the case of disease and the like, personally strive by all the means in their power to be free from the bondage of repeated births and deaths.

Thus,  one has to know what is real by realizing his  body and his  experience of the world are mere illusion created out of the formless soul, the innermost self. . soul is present in the form of consciousness.  The nature of the self is emptiness because it is formless . And it is identified by different masters with different name, such as Brahman, Buddha’s nature, Christ consciousness, Self, Ultimate Truth. 

Self-knowledge or Atma Gnana or Brahma Gnana cannot be attained by one who is without strength or earnestness or without the receptiveness and courage to accept the truth and reject the untruth. If a serious seeker strives sincerely by means of inquiry, analysis and soul-centric reasoning, he will be able to realize it.

It is only seekers sincerity and earnestness in his spiritual pursuit, the knowledge started revealing on its own.  Anyone who has humility and patience and is sincere and ready to drop their accumulated dross and receptive to accept the truth will enter non-dual Self-Awareness when his conviction becomes firm.

People wrongly think that the ego is the Witness, even though the ego vanishes along with waking world.

 All agendas are within the illusion, which appears in the form of mind or universe or waking experience. The self is within the illusion as its formless substance and it is without the illusion as its formless witness. The formless witness is the one which witnesses the body and universe together.  Thus the ordinary awareness is physical awareness (waking) is not self-awareness.  In self-awareness the body is not the body but it is the consciousness, the ego is not ego but it is the consciousness, the world is not the world but it is the consciousness even though they exist but their unreal nature is exposed. Just as the dream becomes unreal when waking takes place, the waking also becomes unreal when non-dual wisdom dawns.

The witness(knower) is that witnesses the coming and going of the three states. This truth has to be grasped mentally to realize the existence of the formless witness. Once this truth is grasped mentally, then one has to cling to the formless witness. Once one clings to this formless witness mentally than the subconscious has the yardstick to accept the truth and reject the untruth. Thus deeper self-search is necessary to understand, assimilate to have firm conviction of what is what in order to get self-awareness.

People wrongly think that the ego is the Witness, even though the ego(waking entity) vanishes along with waking world. 

When one inquire deeply enough the ego disappears one  find there are no separate individuals at all, there is no variety of beings, all are really the undivided consciousness, which is the innermost self. 

The birth, life, death and the world are mere appearance. Their reality is limited to the illusory waking experience alone.   That to which birth, life and death cannot be applied is the formless witness. It is the only thing known that does not vanish, because it is “the unborn.” But as everything that is seen and everything that is known within the waking or dream, is also consciousness, the innermost self. Thus the formless witness and the witnessed (mind or the universe) are one in essence.

Therefore all things are really unborn, uncreated because they are mere created out of unborn material. 

The seeker has to Look within, think deeply, and he finds that the consciousness, the knower is really the innermost self, and that what one regard as his self is ultimately the unborn witness.

That which blocks the way of acceptance of non-dualistic truth even the most thinkers is the ego. If thinkers realize the fact that,  their  body, ego and their experience of the  world are created out of  single stuff than  it is possible for them to   grasp the non-dualistic truth  in lesser time and effort.

The main reason why egocentricity prevents such understanding is that it causes a person to be strongly attached in the belief that consciousness is the support of the individual.
