What a treasure this. The book really should be read in two parts. The first deals with developing a solid meditation practice, Shamantha as the foundation to everything else. Trungpa explains why Shamantha is so vital and the beginning of anything else you want to do. The second part of the book deals more with the other practices of Hinayana and Mahayana and then a little more about vajra. The feel of the book is one of support. If you are struggling to get on the cushion and work with mind, this is a text you could read for inspiration and then again and again for ongoing support.
