"Soul”, which is present in the form of consciousness, is the only reality and there is no second thing other than this soul or consciousness, which is the innermost self.

Wisdom helps to overcome the  ignorance; it does not bring a new thing. one has to  realize the truth here and now. 

Self-Realization is the highest and is the only tool to freedom. Non duality is the true wisdom. In non-dual wisdom there is no second. One has to realize the fact that the self is not the form but self is formless.

By  realizing  the ultimate truth by realizing what is untruth. Deeper self-search reveals the fact that all the three states are mere mirage created out of  the soul, the innermost self. the soul is present in the form of consciousness. Constant reflection is necessary during the early stages of this path.  One has to learn to view and judge the three states  on the base of the formless soul, the innermost  self  and drop the old habit of viewing and judging it on the base of form (‘ego or waking entity’), which is the false self within the false experience(waking).  

The soul is present in the form of consciousness. The consciousness pervades in everything and everywhere in the universe, which is in the form of mind. The mind appears as waking or  dream (duality) and disappears as deep sleep(non-duality). Consciousness is in the rock which is crumbling, in the grass which is growing and then decaying, in the yogi who is meditating, the religious believer  who is  immersed in devotion; there is consciousness because the whole universe is created out of consciousness.

What is illusion? Illusion is where one is bound birth, life, death and universe, and one sees everything on the base of ego. Illusion and attachment are also created out of consciousness; consciousness itself deludes through the illusion. The Egocentric does pious acts, but he does not the consciousness is the ultimate truth and wastes his life away with his inherited beliefs and accumulated knowledge. 

The one, who becomes aware of the fact that,  the consciousness is ultimate reality or Brahman, is eternally becomes free from experiencing the illusion as reality. The ego, body and the world  are part and parcel of the illusion. When the ego is present  then only the body and the world  are present. If ego is not there than  the body and the world  cease to exist. The ego, body and the universe are within the mind. If mind is there then only  universe is there. Thus  the mind itself is the  universe. Limiting the mind to the physical entity is the  cause of the experiencing the illusion as reality. 

Clinging to ego is clinging to the illusion. Clinging to illusion is clinging to ignorance. Clinging to ignorance is clinging is clinging to the illusory experience of birth life, death and universe as reality. By accepting the experience of birth, life, death and universe as reality are accepting the unreality as reality. Therefore, there is a need to know the one which is aware of mind (the experience of birth, life, death and world) is not the body which is born lives and dies within the world , but the soul, which is in the form of consciousness. 

One tries to grasp illusion, but it eludes his grasp. “When one abandoned and discards illusion by accepting the truth that, the formless soul or   consciousness is the true self, then the ignorance disappears and the reality starts revealing itself. Ignorance gives birth to the mind, which is illusion. The mind rises and subsides from the soul,which is in the form of  the consciousness.If one tries to grasp illusion, but it eludes his grasp. “When one abandoned and discards illusion with by accepting the truth that, the  soul or consciousness is the true self, then the ignorance disappears and the reality starts revealing itself.

Illusion is intoxicating material. It grips everyone and everything within the duality. Because it pervades and grips everywhere and everything in duality everyone becomes unaware of the reality. No one has known thy bare reality. Only who are discovered the true self and attuned mentally to the soul, which is in the form of consciousness, realize the duality is mere mirage created out of consciousness.

Illusion has affected the three states, and physical discipline erases not its effect; and men, involved in Strife, are intoxicated with its intoxication are immersed in manipulating the high and low of their physical life. Only through Self-knowledge or Brahma Gnana or Atma Gnana one will be able to overcome the intoxication of illusion.

Chandogya Upanishad:- "When a person is sleeping soundly, free from dreams, with a still mind, that is the Self, fearless and deathless. That is Brahman, the supreme."

"Soul”, which is present in the form of consciousness,  is the only reality and there is no second thing other than this soul or consciousness, which is the innermost self. On the stand point the formless soul or consciousness, innermost self, there is no second thing exists other than consciousness.  Because the whole universe in, which we all exist is created out of consciousness.  There is no second thing exist other than consciousness. Hence it is non-dual (non-duality). The soul or consciousness is ultimate truth or Brahman or God.
