In the current landscape of staff devellopement which tends to attach any spiritual quest for staff well-being, such a book comes as an oasis in the desert. Chogyam Trungpa had become known for his book "Beyond Spiritual Materialism" which was a shock when it was released, both the tone and the originality of the subject. I accidentally discovered the books of Chogyam Trungpa in a library and it appeared to me at dice as the only Tibetan master capable of transmitting traditional teachings in oting cultural barriers. Going against the New Age, this master holds a very ancient lineage comes and presents the spiritual path in its authenticity. Far from the usual clichés about Buddhism, the author invites us to a reflection on Chogyam Trungpa whose innovative and collossale work deserved a synthesis, and it's done. Going beyond the historical framework of the biography, this book is an indispensable introduction to get an idea of the depth of the teaching of Chogyam Trungpa. Moreover, it deftly avoids anecdote; The book presents the many facets of the work still sometimes misunderstood today: comtemplative psychology, the sacred way of the warrior, the dharma art, etc. The character of Chogyam Trungpa turns fascinating, both in the regularity and relevance of his work by the impossibility to define it, always staying to rediscover over the readings, his work continues to take on a new meaning each time we re-read. Research Fabrice Midal (doctor of philosophy) come to account for this complexity; one feels that the author has studied and practiced these teachings, leaving a landmark book!
