There would be no chance at all of getting to know death if it happened only once. But fortunately, life is nothing but a continuing dance of birth and death, a dance of change. Every time I hear the rush of a mountain stream, or the waves crashing on the shore, or my own heartbeat, I hear the sound of impermanence. These changes, these small deaths, are our living links with death. They are death's pulses, death's heartbeat, prompting us to let go of all the things we cling to.
