Bokar Rinpoche Death and the Art of Dying (PDF)

First of all this 140 page book explains what happens when we die. Bokar Rinpoche describes the process of dying for ordinary beings, practitioners and also great practitioners. After we have stopped breathing, our mind continues on through the bardo of the moment of death, then the bardo of dharmata when the mind separates from the body, and finally the bardo of becoming in which we choose a rebirth. 

To prepare for the process of dying, going through the bardos and being reborn to into a favorable body requires a great deal of practice before we die. Bokar explains these within understandable and lucid language and offers a great many insights of how to prepare for death.
