Death is definite. The way to have a peaceful and positive death rests in the way we live our lives. The time of death is uncertain. When it does come, we experience the dissolution of the four elements that make-up our physical body. While we are alive, we have many opportunities to contemplate death, the in between state, and re-birth. Gelek Rimpoche explains that when you know what to expect, you have less fear and regret.
