After introducing the basic theory and practice of mandalas, Martin Brauen describes the main Tantric Buddhist worldview with the aid of computer-generated models. To provide a deeper understanding of the mandala's function, the rich and sacred symbolism of the famous Kalachakra mandala, in its various stages, is then explained in great detail. Western interest in the philosophic, religious, and psychological aspects of the mandala is discussed in the final chapter. Several different approaches to the mystery of mandalas are presented, not with the intention of transmitting incontrovertible truths, but as a means for readers to develop their own understanding of the Tantric worldview.
