Powerful seminar on the mandala principle from the point of view of each of the three yanas. Talk one focuses on the foundational hinayana, with vivid descriptions of the charnel ground as the land upon which the mandala will be built. The second talk describes how beings in the charnel ground develop discriminating awareness, kick-starting the evolution through the yanas. Talk three presents the mahayana, the path of the bodhisattva, point of view: as beings in the charnel ground discover one another, they must learn to work together and develop a social order based on compassion. And the final talk culminates with the vajrayana, or tantric, presentation of the mandala as an opulent kingdom built on mutual sanity and greater vision.
