It is a mistake to suppose that birth turns into death. Birth is a phase that is an entire period of itself, with its own past and future. For this reason, in buddha-dharma, birth is understood as no-birth. Death is a phase that is an entire period of itself, with its own past and future. For this reason, in buddha-dharma, death is understood as no-death.
In birth there is nothing but birth and in death there is nothing but death. Accordingly, when birth comes, face and actualize birth and when death comes, face and actualize death. Do not avoid them or desire them.
