Eventually, he went to Asia and did extensive training in each of the three major Buddhist meditative traditions: Vajrayana, Zen, and Vipassana.
Upon returning to the United States, his intellectual interests shifted to the burgeoning dialogue between Eastern internal science and Western technological science. In recognition of his original contributions to that dialogue, the Institute of Transpersonal Psychology has awarded him an honorary doctorate.
Shinzen's innovative techniques for pain management derived from two sources: The first is his personal experience dealing with discomfort during intense periods of meditation in Asia, and during shamanic ceremonies with tribal cultures. The second is some three decades of experience in coaching people through a wide spectrum of chronic and acute pain challenges.
Shinzen leads meditation retreats in the mindfulness tradition throughout North America, and has helped establish several centers and programs.
