In my opinion, a view on life that is based on the principle of karma and cycle of rebirth should be a pro-active one. Imagine if we don’t believe in reincarnation but in nothingness after death, wouldn’t it be very sad, passive and meaningless, with nothing to look forward to at old age? At that point, no amount of money or knowledge matters anymore. It is often the very reason why old people choose to end their lives. Besides, if nothing were to remain after the passing of this life, one would feel free to do whatever one pleases without any concerns for morality or conscience, hence commit more evil karma and cause endless suffering for future life.
