Simply put, death is a kind of cyclic phenomenon of life. The cyclicality is represented by the fact that rebirth will come after death and birth will eventually end in death again. Our consciousness is like an engine which can turn life on and turn it off, but people in general don’t know how this is done. Be that as it may, life can never end, even at the time of attaining Buddhahood. Granted, that’s an unsurpassed state of existence. As our practice continues to improve, we can also advance to a higher level of existence. Naturally, the phenomena of life are not the inherent nature of life. The nature of life never changes; the phenomena of life, however, undergo an endless cycle of change.
