The world in which you exist is the product of ignorance. If there is no ignorance then the worlds in which you exist cease to exist. The ignorance is present in the form of ‘I’. ‘I’ is not limited to the form alone because the ‘I’ is present only when the form, time, and space are present.
The ‘I’ is absent when form, time and space are absent. Deeper Self-search reveals the fact that the ‘I’ itself is an illusion.
There is no point in inquiring ‘WHO AM ‘I’? WHO AM ‘I’? ‘WHAT AM ‘I’?, inquiry limited to form. It helps the expose the unreality of the ego. In later stages WHO AM ‘I’? ‘WHAT AM ‘I’?, inquiry the seekers will find it inadequate and useless to reach the ultimate end of understanding.
Only sincere and serious seeker will be able to acquire Self-knowledge or Brahma Gnana or Atma Gnana. Those who are sentimentally involved with the Gurus, yogis will remain ignorant hallucinating about the promised bliss or enlightenment.
What is the use of getting enlightenment on the false Self (ego or waking entity) within the unreal world (waking)? It will be false enlightenment.
Self-realization is to realize the ‘Self’ is not you but the ‘Self’ is the formless Soul, which is present in the form of the consciousness. The ‘Self’ is not within the body because it pervades everything and everywhere in all the three states. Thus limiting the Self to the physical body within the illusory world will not yield the truth of the whole.
Thus, it is necessary to realize the ‘Self’ is not the ‘I’ and ‘I’ is not the Soul, the innermost Self. The Soul, the innermost Self is the witness of the ‘I’ which appear and disappears.
Bhagavad Gita: ~ The permanent is always there, only the transient ‘I’ comes and goes. (2.18)
The ‘I’ hides the truth of the whole. .
The earliest ancient sages used the word ‘I’ to the witness of the three states not to the ego as moderns use it and think the ‘I’ without the body is the Self. The seeker has to understand the fact that the fact that ‘I’ is not the Self, but the witness of the ‘I’ is the true Self, which is eternal.
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.
