In Tibetan, authentic presence is wangthang, which literally means, 'field of power'... The cause or the virtue that brings about authentic presence is emptying out and letting go. You have to be without clinging.
Chogyam TrungpaAlthough the warrior's life is dedicated to helping others, he realizes that he will never be able to completely share his experience with others...Yet he is more and more in love with the world. That combination of love affair and loneliness is what enables the warrior to constantly reach out to help others. By renouncing his private world, the warrior discovers a greater universe and a fuller and fuller broken heart. This is not something to feel bad about; it is a cause for rejoicing.
Chogyam TrungpaThere is no promise of love and light or visions of any kind - no angels, no devils. Nothing happens: it is absolutely boring. Sometimes you feel silly. One often asks the question, "Who is kidding whom? Am I on to something or not?" You are not on to something. Traveling the path means you get off everything, there is no place to perch. Sit and feel your breath, be with it.
