A seminar on the four maras: four destructive forces that hinder progress on the Buddhist path. Trungpa Rinpoche teaches on basic goodness, or buddha nature; the birth of ego; devaputra-mara (indulging in personal self-gratification); skandha-mara (solidifying the belief in the components of ego); and gives a review of the whole seminar. This seminar was co-taught with the Vajra Regent Osel Tendzin [talks 3,4,6,8].
