I remember how people would often come to see my master Jamyang Khyentse simply to ask for his guidance for the moment of death. He was so loved and revered throughout Tibet, especially in the eastern province of Kham, that some would travel for months on end to meet him and get his blessing just once before they died. All my masters would give this as their advice, for this is the essence of what is needed as you come to die: "Be free of attachment and aversion. Keep your mind pure. And unite your mind with Buddha."
