As far as beliefs go i agree there must be a soul of sorts, i have read a theory that this soul is a sort of stream of awareness or consciousness, never the same and never static, yet conceptually we can see it as a single event, kind of like a flame, which is not an actual thing but a stream of energy. our mind conceptualizes it and turns the stream into a single fixed event or thing. but the reason i don't believe in, well a lack of personal consciousness is because i read someone once who suggested that even when one is experiencing the boundless infinite consciousness it is still localized, meaning it is still happening to a single person or thing, it isn't happening to your sister or next door neighbor, even if there is not necessarily a feeling of self, it is still happening to one stream of consciousness, not all of them.
i still identify with my personality, thus body as well. i've had experiences of non localized awarenes, i've had experiences of what some call the silent witness where one disappears and there appears to simply be awareness, i've had an out of body experience as well, but i'd be lying if i said i don't still identify with my body. i was curious about this until i read a passage which suggests that perhaps the cause is deeper segments of my personality i still identify with are the cause. i don't know one way or the other, sometimes its hard to tell where my truth ends and my beliefs begin.
you mentioned a single soul inhabiting various life forms at once, is this something you have expeirenced? one passage in your blog suggested you were under hypnosis and experienced perhaps a differnet life, is this what you mean?
