““It is no less silly to trouble yourself about death than you do about gravitation. Can you realize that death, which you have yet no immediate experience of, is the greatest of evil? We dare to declare death to be one of the blessings which we have to be thankful for. Death is the scavenger of the world; it sweeps away all uselessness, staleness, and corruption from the world, and keeps life clean and ever now. When you are of no use for the world it comes upon you, removes you to oblivion in order to relieve life of useless encumbrance. The stream of existence should be kept running, otherwise it would become putrid. If old lives were to stop the running stream it would stand still, and consequently become filthy, poisoned, and worthless.””
