Western Buddhism evoloved through a variety of transformations of Buddhism from the East, becoming establishing through its engagement by the "counter-culture" and subsequent integration into "New Age" spiritual and philosophical worldviews. It has ultimately entered into secular circles and scientific psychology, currently resulting in the conception of "secular" Buddhism. Both of these phenomena provide fascinating examples of the formation and development of new expressions of an already successful and popular world religion. Since Buddhism originally migrated from the East to the West, it also exemplifies the transmutation of a religion when it transfers from one living civilization to another. This lecture will address the historical and cultural aspects of the passage of Buddhism from East to West and investigate the details of the origin, development and practice of both western and secular Buddhism.
