For this reason, also, death is definite. Each moment that passes bring us closer to death. It is like the archer who shoots the arrow through space until it reaches the target. The arrow does not remain in space even a moment. In the same way, from the day we are born until we die, life does not stay still for even a moment.
Life is also like a flowing river.
As the river does not cease its flow even for a moment, so does life, gallops on. It is ever changing, yet ever the same in its change. Our life moves daily closer to death like the prisoner moving towards his place of execution. Our life has no predictable span, especially in this world system. Some beings die in the mother's womb, some at the moment of birth, some as infants, some in youth and some in old age.
