This is an excellent introduction to Buddhist Tantra, Vajrayana. Lama Yeshe was one of the greatest teachers of the 20th century. Lama really understands the mind and especially the mind of the modern westerner making his teachings very accessible. I recommend this book to anyone interested in vajrayana or buddhism in general. My father loved the wisdom of this book so much he gave a copy to his mother!
I feel that one of the primary gifts Lama Yeshe has brought to the "western" world as a Tibetian, is his ability to explore and describe Tantra in great depth but from a culturally independant perspective. Much of the really authentic, un-americanized, non-newage etc info and teachings on Tantra is essentially coming from various Tibetian Lamas and practitioners, but their perspective on Tantra is usualy always heavily overtoned by a great deal of cultural (Tibetian) views, beliefs etc that are quite independant from Tantra which is free from all cultural and social dynamics. Lama Yeshe has stepped right through all that, and goes into the essence of Tantra itself. Not Tibetian Tantra and not American tantra... but for the most part, just the essence. As an introduction to Tantra this book touches on a broad array of issues and aspects that are all key aspects of Tantra and the Tantric perspective. It was a pleasure to read, and higher recommendable.
