What I believe:
>each form of existence is a school to prepare you for the next one
>the life after this could be beyond our comprehension
>just like a caterpillar cannot comprehend being a butterfly yet will become one
>the soul persists throughout and across existences
>there's a separation between the soul and physical body, the soul is a passive observer in the pre-determined realities
>the soul is the reader, the 'body' the character in the book, the soul cannot change the course of events but still lives vicariously through the body and learns from it
>free will experienced by the body may be an illusion within the predetermined reality
>this preparation across realities could be to prepare the soul for something else
>spiritual fulfilment or awakening, gnosis, or a connection to God are signs that the soul is progressing or learning
and if I'm completely wrong and there's nothing, then the comfy void awaits.
