The commentary interprets its root text within an elaborate framework of tantric visualisation and meditation that is based on an expanded form of the Buddhist Yoga Tantra mandala, the Vajradh?tu-ma??ala. At its heart is the figure of Mañju?r?, no longer the familiar bodhisattva of wisdom, but now the embodiment of the awakened non-dual gnosis that underlies all Buddhas as well their activity in the cosmos.

The book contributes to our understanding of the history of Indian tantric Buddhism in a period of significant change and innovation. With its extensively annotated translation and lengthy introductions the book is designed to appeal not only to professional scholars and research students but also to contemporary Buddhists.
