In this dialogue series, Brother Wayne Teasdale and Ken Wilber discuss the advent of an integral mysticism in the postmodern world. Reflecting on their own spiritual experiences, the relation of science to spirituality, the lives of the great inter-spiritual pioneers, and how youth culture is revitalizing the mystical traditions, Brother Wayne and Ken show how an integral perspective can bring the revelations of mysticism into everyday life. In so doing, we learn to give fullest expression—as parents and professionals, students and seekers—to the Mystic Heart in each of us. If, as historian Arnold Toynbee put it, the introduction of Buddhism into the West “may well prove to be the most important event of the 20th century,” we might also argue that the re-discovery of the contemplative roots of Christianity will be equally important. And as we enter the 21st century, it stands to reason that the recognition of a common mystical ground between Buddhism, Christianity, and the other World Religions will be the most important event of all.
