When will "I" cease to be?

[Henosis]

I see densities as stages of expanding (or better said growing over) of the consciousness: no awareness --> awareness --> self awareness --> spiritual awareness etc. --> ocean of consciousness or the Supreme Self.

I think it is posible for some people in this density to dwell with the mind in higher planes. At least for some time. Spiritual awareness (opening of the heart) is the lesson/goal in this density so it is the highest permanent state for now.

Let me quote Sri Ramakrishna:

The  Vedas  say  that  ‘I-ness’  vanishes  only  when the  mind  ascends  to  the  seventh  plane.  ‘I-ness’  only disappears  upon  attaining  samadhi.

I suppose my question in general is dealing with the nature of the Absolute. The absolute state of non-duality. In my understanding, the first emanation of the Absolute would be intelligence, or awareness. While this awareness is awareness of unity, there is a still a very, very subtle state of duality between shiva/shakti or being/awareness. Awareness/intelligence is still an emanation.

It seems impossible to draw a conclusion of whether the Absolute is active/inactive. If it is inactive, then there is no way for existence or creation to have ever occurred. If it is active, it seems it would be subject to change. It would still be drawing on the power of the essence and the creative force would not be the essence.

The Absolute or Unity must have two aspects, one of which is inactive or permanent, which I would equate with unity or Shiva. The other aspect must be active, which I would equate with intelligence or Shakti. It is often said the Absolute has two aspects, implying that there is some sort of fundamental duality built into the One. Many philosophies draw the conclusion that the Absolute must have overflowed in its superabundance, producing Shakti or awareness/intelligence. I tend to lean toward this approach, as it seems to be one of the only solutions to this paradox.

As it relates to this question, I believe "I" would be vanquished upon the nullification of self-awareness to awareness...I think this would likely take place upon completion of the octave.

EDIT: Ra quotes supporting the never-ending mystery...

"However, it has been impressed upon us by our own teachers that there is a mystery-clad unity of creation in which all consciousness periodically coalesces and again begins. Thus we can only say we assume an infinite progression though we understand it to be cyclical in nature and, as we have said, clad in mystery."

"The one undifferentiated intelligent infinity, unpolarized, full and whole, is the macrocosm of the mystery-clad being. We are messengers of the Law of One. Unity, at this approximation of understanding, cannot be specified by any physics but only be activated or potentiated intelligent infinity due to the catalyst of free will. This may be difficult to accept. However, the understandings we have to share begin and end in mystery.
