i have seen a lot of things that convince me that there is a 'spirit world' or maybe more than one~
personally, i follow the teachings of buddhism regarding reincarnation. i have done several death meditations, and believe that the personality is dropped with the body, and what remains is beyond description. but it goes back into the 'pool of life', if the consciousness has not reached a place where it can hold itself together~ that is what i strive for, not to be a shattered consciousness.
