So you mean I must understand Life so that I am ready to face death?
How do I know death is a door to another "world",
death could mean End of Life, ultimate ending, no more story.
i don't think your fear is realistic, even from your perspective.
if death really is the end, then there is nothing to fear is there?
if life goes on after death, then there is a whole new can of worms or possibliities which not all of them may be good.
think about it, one can't suffer or even be conscious of or feel fear unless one is alive. afterlife would still mean alive. understand?
taken another way, some people's fear is that death is not the end and they are forced to relive life over and over. that can be a hell of it's own, do you not see that?
why do you think some people commit suicide or people with terminal illnesses in great suffering want to die?
it all depends on the circumstances one is in and for some people life is what is hell. don't you understand that? get out of yourself for a moment and pay attention to the news or lucidly recall that there are people who suffer in horrendous situations from birth to death. some are starving, diseased, outcast, ridiculed etc. the list of cruelty and suffering is endless and myriad.
seriously, one has to be really self-centered or dumb to not realize this. one only need to read a history book, look around you at others in life, watch the news etc. life is not all roses and peachy either. like, duh??
