Little Hawk... I am familiar with the concepts and for want of a better word, 'feelings' you describe about yourself...and your selfness. There are similar things explained and used in Zen meditation, in bio-feedback....and of course, in theories of reincarnation.

I KNOW that it is quite possible to train the mind to "stop .... compulsive thinking and just observe silently...observe...listen to the silence...observe..."...to various degrees. I often wish I had developed the ability, as it could be useful to 'retire' from daily coping for awhile. I have met several people who did such things to varying degrees, and while I admire the discipline, I simply don't make jumps to metaphysical constructs ("...the essential state of being which allowed my personality to come forth out of pure being will go on...") about its basis. This essentially a religious viewpoint, whether it is framed that way or not, and involves implicit assumptions about the very nature of reality.
   Now, this can well be a useful model, or metaphor, to aid in the mind-focus techniques you refer to...but I'll confess, I intentionally refrain from using such metaphors personally, specifically to avoid getting caught up in accepting incompatible ideas. (Yeah, I may be missing something valuable, and it 'could' be possible to have both...but...old habits die hard.)

So... "That's theoretical, though. We'll have to wait and see. ;-) "... yep...and a LOT longer than *I* have, I'd guess...
