Nobody knows what comes after death.
Religions of mankind tell us of paradise, of rebirth, purgatory and of eternal damnation.
And perhaps it is the promise of a place. ANY place at all after death- the comfort in knowing that you'll still continue to exist at another level of consciousness. That you are not totally gone.
Different cultures treat death differently. Some funerals in Eastern religions are ceremonious- almost festive, heavily ritualized and symbolic. Some western funerals are subtle, quiet reflections on a life that once was. I've had the opportunity to experience both.
If psychic mediums are to be believed, a different type of life exists and learning does continue on the other side. Higher learning.
