First,  realize what is this I to unfold the mystery hidden by the 'I'. The 'I' hides the truth of reality. 

What is this ‘I’? 

The ‘I’ is not a thought. The ‘I’ is the mind. The mind is the whole universe. The universe appears as waking or dream (duality and disappears as deep sleep (nonduality). The one that appears as waking or dream (duality) and disappears as deep sleep (nonduality) is the Soul, the innermost Self. The Soul is present in the form of consciousness. The consciousness pervades everything and everywhere in all three states.

Without knowing what mind is, it is impossible to realize the truth, which is beyond the form, time, and space. People think the mind is within the body, but deeper self-search reveals the fact that the world in which you exist itself is the mind. When the ‘I’ is there then only the mind is there. If the mind is there then only the universe is there. If the universe is there then only the waking is there. Thus, it is very much necessary to realize the ‘what ‘I’ is in actuality. Without knowing ‘what is this ‘I’ it is impossible to realize the ‘I-less’ truth, which is beyond the form, time, and space.

Till you hold the ‘Self ‘as the ‘I’ you will never be able to get Self-realization.‘I’ hides the Soul, which is the innermost Self. ‘

I’ is ignorance.

‘I’ is the duality.

‘I’ is form, time, and space.

‘I’ is the universe.

‘I’ is waking.

‘I’ is the dream.

‘I’ is the illusion.

‘I’ is the experience of birth, life, death, and the world.

Remember:~

Without the ‘I’ there is no ignorance.

Without the ‘I’ there is no duality.

Without the ‘I’ there is no form, time, and space.

Without the ‘I’ there is no universe.

Without the ‘I’ there is no waking.

Without the ‘I’ there is no dream.

Without the ‘I’ there is no illusion.

Without the ‘I’ there is no experience of birth, life, death, and the world.

The ‘I’ hides the truth of the whole. The ‘I’ hides the truth.

That is why Ashtavakra Gita 16:10:~ If you desire liberation, but you still say ‘I,’, If you feel the ‘Self’ is the ‘I’, you are not a wise man or a seeker. You are simply a man who suffers.

Bhagavad Gita: ~ The permanent is always there, only the transient ‘I’ comes and goes. (2.18)

A perfect understanding of ‘what is what’ is needed to realize the ultimate truth or Brahman or God.  Thus one must realize how this world, which confronts him, is an illusion? And on what standpoint the world is an illusion. 

Without knowing ‘what is mind? ‘What is the substance of the mind?’ ‘What is the source of the mind?  The truth will not reveal. Thinking the mind is within the physical body is the greatest obstacle in pursuit of truth.  Thus, a deeper investigation is very much necessary in order to unfold the mystery of the 'I'.:~Santthosh Kumaar
