The answer to this question is probably impossible to discover, but I believe, if there is to be a religion, it must ONLY attempt to explain that
which we DO know...which is that he does not cease to exist, and that's pretty much it.
To me I believe in Reincarnation, and that your spiritual individuality (what makes us different from eachother, because if we had no individuality,
we'd be one being, many bodies) is comprised of many past experiences, which effect your life later on, though minutely, because of the chemicals in
our brain being so predominent.
Which is why I believe it should be the quest of every sentient being, to discover themselves, who they really are, not what their genetics is, and if
you can do that, you will have for this life, freed yourself from your "chemical" bonds, and obtained all the wisdom of your past lives, and be
"enlightened" or at least happy, because you are no longer bound to the happy sad chemicals.
I think I've actually obtained some success with this, I should be tested for any chemical differences in my brain
because my happiness and sorrow
is no longer bounded by "emotion" if you will, that is if you define emotions as chemical responses in the brain.
Because while things go great for me, some important subtleties have not happend at all
and nothing has happend as I planned, in a sense I should
be a horribly depressed individual
Anyways, point I'd like to make, is life is a cycle and so your deceased loved one will probably be reborn some day, with the experiences they had in
this life carried with them, but not as memories, but as feelings, which is more important...sadly though most of the world is enslaved spiritually,
and those feelings will be supressed for the idea that you only live once and all your past lives is crap and that of course is why much of the world
A sad existance, you can obtain enlightenment in one life, but because of general concensus, you lose that enlightenment once you are
