When the Self is not you then what is the use of saying I AM THAT without realizing what is that.+

Realize Soul, the Self is not you. So you are not that to say I AM THAT. You are a reality within the universe but the universe is merely an illusion.

Without the illusion, you cease to exist. Without the Soul, the Self, the universe ceases to exist. You are the birth entity whereas the Soul, the Self is unborn eternal.

When the Self is not you then what is the use of saying I AM THAT without realizing what is that. Why you are saying I AM THAT when the Self is not you but the Self is the Soul hidden by the ‘I’. 

You are saying I AM THAT within the world in which you exist. The world in which you exist is the dualistic illusion or Maya. It is of no use to say I AM THAT within the dualistic illusion or Maya.

The dualistic illusion or Maya hides the Self. Realize the ‘Self’ is not you but the Soul, which is present in the form of consciousness. 

The dualistic illusion or Maya is present in the form of the ‘I’. The ‘I’ appears and disappears. The ‘Self is not the ‘I’. The Soul, the ‘Self’ is always present and is hidden by the ‘I’.

Remember:~

The ‘Self’ is permanent and the ‘I’, is impermanent. The ‘I’, which appears and disappears is not the Self. The Self is hidden by the ‘I’. the ‘I’ is perishable whereas the Self is imperishable.

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

Why are you struggling to find out who you are? You will never find the answer if you get stuck to the ‘I’. Find out ‘what is this ‘I’, which appears and disappears. What is that is aware of the coming and going of the ‘I’?

Without realizing ‘What is this ‘I’? you will never be able to realize the mystery of the ‘I’. The ‘I’ is the most intoxicating stuff. 

Those who use the word ‘I’ for the ‘Self ‘will never be able to cross the threshold of the dualistic illusion.

The ‘I’ based teachings will not transport the seeker to the ultimate end of understanding.

The ‘I’ is the cage for the Soul. ‘I’ is the cause of ignorance. Self-knowledge or Brahma Gnana or Atma Gnana is the only weapon to get rid of ignorance.

The ‘I’ based teachings will not transport the seeker to the ultimate end of understanding. 

Perfect understanding of ‘what is this ‘I’ leads to the realization of the truth beyond the form, time, and space.

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. : ~ Santthosh Kumaar
