A leading scholar in Tiantai (Tendai) Buddhism will clarify the true nature of reality in relation to environmental concerns and the relevance of Buddhist practice for today.
Lecturer: Dr. Brook Ziporyn
Associate Professor, Department of Religion, Northwestern University
He specializes in Chinese Buddhism, Taoism and Confucianism. He earned the Ph. D in Chinese philosophy at the University of Michigan and has taught Buddhism and Chinese thought at the University of Michigan, Harvard University, the Chung-hwa Institute of Buddhist Studies,Taiwan, and Northwestern University (since 1998).
An interesting journey through both Theravadin and Mahayana sources for a Buddhist Ecology, as well as the difficulties with such a concept (there is no Buddhist word for ecology, for instance). Each of the stories he tells should be ready at hand for students of Buddhism interested in dealing with our ecological crises. Highly recommended.
