Good introduction. This is not a translation but an adaptation by the translator, too bad. Especially since it seems to have a bookish knowledge but has clearly not practiced yoga of tumoral or physical description seems incomplete. Conversely the literature available in English on 6 Yoga Naropa are more complex. So this book is to read it first and he enlightened me, I'll read another. But this is not a book for enlightenment is more to satisfy his intellectual curiosity.
