In the contemplation of truth, you come to the realization that there is no external reality outside of the reality of consciousness.
This revelation will lead you to the understanding that awareness and consciousness are thus one and the same. I am this aware space, this aware presence.
This understanding matures and dissolves the impression of duality and establishes that “I” refers to the Self, to the one reality, and the Self, being the one reality is the universal I.
That I AM.
“I am That” and “all is That” becomes your established understanding and the bliss of the Self.
Ananda, bliss, permeates your entirety.
