Sincerely disappointed with the first 2 posts here, which sort of said "take a religion" or "look at religion". That's not right to say.

Be religious, or worship an entity, by all means, or not at all, but don't answer somebody's genuine question by saying "take a religion". That's inappropriate.

I don't think one life reincarnates to another individual - if reincarnation exists it has nothing to do with population. Perhaps 1 tree could die, and its death could fuel a thousand insects. Now wouldn't that be brilliant - but do trees even have souls?

Human beings have a funny way of disregarding anything that is inanimate or non-motile.

Karma stems from conscience and altruism. Altruism, some say, is Human Nature, innate.

Who knows what happens after life? Will humans ever find out? Sometimes this entertains us - the idea, that is - in books, movies, art. Sometimes this saddens us.

Just do, whatever it is that you do.
