If you pursue and rest in the I Am, you obtain liberation while in bliss. If you pursue the subject, the Witness, it keeps receding more and more into the Void so that eventually you are the Void.
But resting in the I Am, you feel the separation between you and the I Am, allowing you to realize you can only Be the Witness, the Absolute. It is not observable, it is not part of the world. It cannot be caught or possessed. You are not part of this physical/energetic world as the Absolute.
Then, by going back and forth between being the Witness and identifying with the I Am, you gain the final understanding that you are both. As long as the body lasts you are an incarnated divine being joined by awareness with the Witness.
COMMENT BY STUDENT:
You started nice, you cannot seek the absolute, you can only be it! After you started writing about seeking and you destroyed the beautiful start!
You belong to that large class of people that have the mistaken concept that all you have to do is stop seeking, stop spiritual effort and all will be revealed. That is absolutely not true. This is a concept that traps you in mediocrity.
Ramana would not agree with that; Nisargadatta and Siddharameshwar would not agree; Robert Adams an I disagree with that; Muktananda, Chetanananda would disagree with that. The six Zen masters I studied with would disagree with that. Buddha would disagree as would all Tibetan Lamas. Ramaykrishna would disagree with that. As a matter of fact, I can't think of any great teacher of present or past who would agree that effort is not necessary except the legion of posers on Facebook.
Only lazy and confused people believe as you do, or the tons of Facebook gurus that make a living off people who want to believe that spiritual effort is useless.
