I was reading the Tibetan Book Of The Dead and came across this:
'0 nobly-born, that which is called death hath now come. Thou art departing from this world, but thou art not the only one; [death] cometh to all. Do not cling, in fondness and weakness, to this life. Even though thou clingest out of weakness, thou hast not the power to remain here. Thou wilt gain nothing more than wandering in this Samsara. 9 Be not attached [to this world]; be not weak. Remember the Precious Trinity.10'
(Dharma notes: The Trinity means the Buddha, Dharma, and Sangha)
In other words....let go. Not just when you're dying either. Living beings can do it too.
Let go.
