No I do not know anything of Chogyam Trungpa's life. The book was recommended to me by a Sangha member of the temple I visit, Kagyu lineage, when this person heard I was interested in Buddhist psychology. Someone else commented briefly that he had a controversial life and some really enjoy his view and others feel he has transgressed the boundaries ... they gave me no examples though and just ended there. At the time I felt it was best not to be inquisitive and left it.
