Nondual Awareness is the nature of the Soul, the Self, which is present in the form of consciousness.+

Non-dual Awareness is the nature of the Soul, the Self, which is present in the form of consciousness. There is no second thing that exists other than the Soul the Self. Thus, the Soul, which is present in the form of consciousness, is the ultimate truth or Brahman or God.

I AM- Awareness is physical awareness.  Self–Awareness is not physical awareness. Physical awareness is present in the form of the universe. The universe appears as the waking or dream experience.  The physical awareness (universe)  disappears as deep sleep(Soul). 

Self-awareness or Brahmic awareness arises when the Advaitic wisdom dawns. Advaitic wisdom dawns when Soul the 'Self' becomes aware of itself in the midst of the form, time, and space (duality or waking) by realizing the form, time, and space are one in essence.

If one has understood 'I’ or ‘I AM ‘is not the Self and what really is ‘I’ or ‘I AM’, there is no necessity for the pursuit of truth.  When in deeper Self-search one becomes aware of the fact that, the ‘Self ‘is neither the body nor the ‘I’.

Remember:~

Self-awareness is not your own state because the Self is not you but the Soul, which is present in the form of consciousness. Holding the Self as ‘you’ is a great error.

It is wrong to say Gnani sees nothing in Self-awareness.   The commoner viewing the world will see differently from a Gnani viewing the same world. Each one interprets the world that they see in terms of their existing knowledge. The commoner sees everything based on the ego, therefore, sees himself and the world in which he exists as a reality whereas a Gnani sees himself and the world in which he exists as an illusion created out of consciousness and he is fully aware of the fact that there is no second thing exists other than the Soul or consciousness.

The universe has no independent existence. The Soul which is present in the form of consciousness alone has real existence. The universe is merely an illusion created out of consciousness. 

The world is both real and unreal. It is real because it is a manifestation of consciousness, but is unreal, in the sense, that it is not absolute and eternal like consciousness itself.

People's approach is more practical, and they stuck with the reality of the world, they take it as real. That is why all the confusion.

A Gnani sees only unity in diversity, just like a goldsmith estimating the gold in various items of jewelry sees only gold. When one identifies the Self with the form then only the form, time and space are present. But when one transcends form, time, and space the duality never remains as reality.

The universe remains a reality until there is ignorance. When ignorance vanishes, there is only Self-awareness. In Self-awareness, there is only non-dualistic awareness in the midst of dualistic illusion or Maya.

Perfect understanding of ‘what is what’ with full and firm conviction leads to the realization of the Self hidden by the dualistic illusion or Maya.:~Santthosh Kumaar
