A simple and pure book, yet infinitely deep. I do not recommend it for those just starting meditation as it neglects techniques which will be necessary for the beginner. To such people I'd have to suggest the excellent 'MEDITATION: THE BUDDHIST WAY OF TRANQUILLITY AND INSIGHT' by KAMALASHILA. But for those who are fairly well grounded in meditation and who have more than an intellectual notion of buddhism then read this book. A real breath of fresh air.
