[It you do not believe that there is life after death, you may skip reading the following.] It is true that we in the world seek pleasure, fun, entertainment, recreation...so that we can have a good time, forget our troubles and be happy. The desire is inherent in us. I see that all the temporal happiness we seek are for the moment only. For example, you go on a week's cruise ~ after the week, the enjoyment is just memory. Personally, I don't see how such passing happiness can be truly satisfying. To me, only unending (permanent) happiness is meaningful. If I know in advance that I won't be happy in the next life, then I don't think I can truly feel happy in this life anymore. On the other hand, if I know that I'll be happy for all eternity, then whether I am happy or not in this life becomes rather unimportant. Last, if we are only concerned about being happy in this life, we can easily forget planning for our eternal future ~ this then would be a huge oversight.
