As the manifestation of the impermanence of life, death is not a one-time event but occurs at every moment of life. Since the aggregates are in a state of constant flux, birth (seen as arising) and death (seen as passing away) are always present in juxtaposition to each other.These momentary lives and deaths are one phase of the cycle. From another perspective death is nothing but the arising of the new state in place of the preceding one.
