What is the use of saying I AM THAT when the ‘Self’ is not you but the ‘Self’ is the Soul.+

What is the use of saying I AM THAT - when the ‘Self’ is not you but the ‘Self’ is the Soul, which is present in the form of consciousness?

Your existence is limited to form, time, and space whereas the Soul, the Self is a formless, timeless, and spaceless existence.

People say I AM THAT ~ I am God, I am Brahman. But when Brahman is, how can "I" remain? Only Brahman remains, not I, it is erroneous to use the word ‘I’ for the Self, because ‘I’ represents form, time, and space whereas the Soul, the Self is a formless, timeless, and spaceless existence.

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

The ‘I’ disappears as deep sleep, so what is the use of being attached to it? It is impermanent and illusory because ‘I’ is physical awareness. Physical awareness is not Self-awareness. ‘I-less awareness is Self-awareness.

Bhagavad Gita: ~ “You must first see the ‘I’ as illusory before you see others as illusory. ~ CH.2 v.16

It is erroneous to identify the Soul, the Self as 'I' or 'I AM' because the Soul, the Self is not 'I' or I AM’. The Soul, the Self, is that witness of the 'I'.

To realize the false nature of the ‘I’, the Self-knowledge or Brahma Gnana or Atma Gnana is necessary.

The Self is not ‘I’, but the Self is the Soul which is the witness of the ‘I’. Holding the ‘I as the Self leads to hallucination based on the imagination. : ~ Santthosh Kumaar
