Human life is pretty short

Human life is pretty short. It is good if we can live for another twenty, thirty, or even forty years. But we wont remain forever. Therefore, do not try to make plans for a long life. You should instead think about the uncertainty of coming of death, and the uncertainty of conditions that would cause death. You should think about these on regular basis. This would inspire us to practice dharma and prevent us from doing many worldly things.
