Death, in reality, is just an expression of not having practiced properly. As long as you have practiced well, death is not suffering. It can be faced with cherishing. (It may be) the end of samsara, the beginning of nirvana. This is death. And on that day, the attainment of Buddhahood has started. If we do not practice, then samsara is never going to come to an end! It is a never-ending game.
