With this work there is no secret about the symbolism of the Vajrayana (Tibetan Buddhism), although some rare descriptions are still circumscribed only to the initiated. The black and white illustrations are at the height of the delicacy of Tibetan art, and text associated with a great pedagogical clarity. Through these symbols is a whole section of Mahayana Buddhism which is revisited. In addition to a 26-page glossary, appendices resume complement legend churning of the ocean, and the chakra system.
