A live online discussion with integrative sleep specialist Ed O’Malley, Ph.D., and Tibetan meditation master Geshe Tenzin Wangyal.

How do the light of day and darkness of night impact our experience as human beings, including the quality of our sleep? What is light, from the perspectives of both modern science and ancient Tibetan wisdom? Ed O’Malley and Tenzin Wangyal Rinpoche explore the implications not only of sunlight, but also of the clear light of awareness and the five pure lights described in the dzogchen teachings of Tibet. Join us for a fascinating inquiry into our universe of light and dark.
