I encountered the Buddha Dharma in 1965 while working with Tibetan refugees in northern India (see Widening Circles, A Memoir), and it became central to my life and work. My revered teachers in the Tibetan Kargyu tradition include the Ven. 8th Khamtrul Rinpoche, Sister Karma Khechog Palmo, Ven. Dugu Choegyal Rinpoche, and Tokden Antrim of the Tashi Jong community.
My main meditative practice is vipassana in the Theravadin tradition, for which I thank Nyanaponika Thero and Rev. Sivali of Sri Lanka, Munindraji of West Bengal, and Dhiravamsa of Thailand, as well as a number of fine American teachers.
When I returned to graduate school, I harvested teachings from Buddhist scriptures. My doctoral work at Syracuse University focused on the Buddha's doctrine of dependent co-arising and its convergences with general systems theory (see my book Mutual Causality).Extensive fieldwork in Sri Lanka with Sarvodaya, a village self-help movement (see my book Dharma and Development), taught me more about the relevance of Buddhist teachings to social change--as have also my many colleagues in the Buddhist Peace Fellowship, where I serve on its Advisory Council. My understanding of Engaged Buddhism is reflected in my books Mutual Causality and World as Lover, World as Self.
