According to the mandala principle, a prominent feature of tantric Buddhism, all phenomena are part of one reality. Whether good or bad, happy or sad, clear or obscure, everything is interrelated and reflects a single totality. As Chögyam Trungpa explains in this work, from the perspective of the mandala principle, existence is orderly chaos. There is chaos and confusion because everything happens by itself, without any external ordering principle. At the same time, whatever happens expresses order and intelligence, wakeful energy and precision. Through meditative practices associated with the mandala principle, the opposites of experience--confusion and enlightenment, chaos and order, pain and pleasure--are revealed as inseparable parts of a total vision of reality.
