What is Gnana? Gnana means the full and firm realization of truth – a realization beyond all doubts, change and contradiction.
Neither the control of breath, or regulating the breath, nor the performance of selfless service, nor by devotion to gods and gurus, not the performance of penance, nor pilgrimaging, nor by yoga nor by scriptural mastery, the ignorance will not vanish. But only through nondual wisdom the ignorance can be eradicated. The three states are state of ignorance. All the three states are falsehood. The formless substance and witness of the three states is real and eternal.
Sage Sri Sankara-BG: - [Jnana Viheena Sarva Mathena Bajathi na Muktim janma Shatena] - one without knowledge does not obtain liberation even in a hundred births, no matter which religious faith he follows.
The mind is in the form of Universe. Universe appears as waking or dream. Waking as it presents itself is unreal, same way as the dream. Thus waking or dream is simply illusion created out of consciousness. To the man within the universe it is not an illusion because he has the conviction that he is an individual separate form the universe and he is born in this universe and universe existed prior to him. Until this conviction is there he is bound to believe the birth, life, death and universe as reality. Only in deeper self-search he becomes aware of the fact that, the mind is not within the body but body and the universe are within the mind. And he also becomes aware of the fact that mind itself is the whole universe ,which appears as waking or dream and disappears as deep sleep.
To think once own body and his experience of the world is an illusion is difficult matter, unless one realizes the self is not physical but it is formless soul it is difficult to have glimpse of truth.
When one realizes the fact that, the self is not physical but the formless soul, naturally the body and universe becomes illusion.
The mind (universe)is emanating from soul (consciousness) means the mind is being effect from consciousness is not different from it. Deeper analysis shows it. Analysis needs deeper thinking and reasoning. Mind is whole universe thus it has a form. But where is the form in consciousness (soul) because consciousness is like an ocean and mind is like wave. The universe is same consciousness, as the ocean produces the wave, so the consciousness produces the mind (universe).
The moment one knows the mind (universe) is consciousness, and then there is no ignorance. If one knows consciousness as self then everything is consciousness, the consciousness is second to none. The mind is consciousness but due to ignorance one mistakes it for something else. One thinks the self is within the body; but the self is without the body and the world.
Mind ceases to exist without the matter. Without the matter mind ceases to exist as mind but it exists as matter- less awareness or consciousness. Without the mind neither the world nor its perceiver can exist.
Without the matter there is no duality. Without duality there is no experience. Without experience it is non-dual reality. Therefore, whatever prevails without the mind is ultimate reality.
The true nature of the soul (consciousness) is camouflaged by the illusion/duality. To know the truth one has to discover and realize the formless substance of the mind or illusion. One has to learn to view and judge the worldview on the standpoint the formless soul as self. Self-Knowledge or Bramha Gnana or Atma Gnana is the prime goal of the truth seeker. This goal is hidden within the mind as its invisible substance and witness. Therefore, it is necessary inquiry, analyse and reason in to the nature of mind/ duality/illusion in order to unfold the mystery of mind or duality or illusion.
The validity of the judgements which one continually pass on events taking place around him is not denied but all these experiences are happening within the universe (waking or dream) is mere illusion. It is true that the phenomenal world is the outcome of ignorance, but it has a certain relative reality but the relative reality is mere illusion from ultimate standpoint. Thus the relative reality is based on the false self within the false experience because there is no second thing exist other than consciousness thus there is only nondual reality.
