A collection of authentic translations from classical sources provides an accessible introduction to Tantric Buddhism based on the writings of Dalai Lamas throughout history, in a volume that is complemented by the thirteenth Dalai Lama's survey of the principle tantric systems.
Quite an esoteric work that explains the commentaries given by the several Tibetan Buddhist Masters on the subject of Tantra. Requires a re-read for the entire message to sink in, if it ever will.
