As I understand it, we dissolve the personality shell and merge with the Source at the end of the octave. The Higher Self is an interactive record of all we have experienced - very similar conceptually to a Star Trek holodeck recreation of historical personages. You can interact with it, but it can no longer co-create. Another analogy would be reaching the end of an RPG game with a character, and stepping away from the computer, having integrated the character's experiences and memories into your actual identity.
The next octave is then analogous to sitting down again at the computer to play a different game with a different character, but it's still you who is playing (remembering that the real you is the Logos).
I am not personally crazy about this notion, but higher density beings have described it to me as "a perfect part of a perfect plan" so I choose to trust that any discomfort I have about it is due to the limitation of my vision in 3D, and that it all makes perfect sense from a less limited perspective. Perhaps by 6th density we become very acutely aware of how artificial and limiting a construct a personality or "individual identity" is, and want to shed it to regain that wholeness and oneness and perfect integration into the ocean of being which we all have once known.
