Guang Xing gives an analysis of one of the fundamental Mahayana Buddhist teachings, namely the three bodies of the Buddha (the trikaya Theory), which is considered the foundation of Mahayana philosophy. He examines how and why the philosophical concept of three bodies was formed, particularly the Sambhogakaya , which is the Buddha to be worshipped by all Mayahanists. Written in an accessible way, this work is an outstanding research text for students and scholars of Mayahana Buddhism and anyone interested in Buddhist philosophy.
