Many Buddhists understand the Round of birth-and-death quite literally as a process of reincarnation, wherein the karma which shapes the individual does so again and again in life after life until, through insight and awakening, it is laid to rest. But in Zen, and in other schools of the Mahayana, it is often taken in a more figurative way, as that the process of rebirth is from moment to moment, so that one is being reborn so long as one identifies himself with a continuing ego which reincarnates itself afresh at each moment of time. Thus the validity and interest of the doctrine does not require acceptance of a special theory of survival.

Life exists only at this very moment, and in this moment it is infinite and eternal. For the present moment is infinitely small; before we can measure it, it has gone, and yet it persists forever. This movement and change has been called Tao by the Chinese. . . . A sage has said that if we try to accord with it, we shall get away from it. But he was not altogether right. For the curious thing is that you cannot get out of accord with it even if you want to; though your thoughts may run into the past or the future they cannot escape the present moment.

You do not play a sonata in order to reach the final chord, and if the meanings of things were simply in ends, composers would write nothing but finales.
