(Spirit Rock Meditation Center) After a brief review of the first two talks in this series, we explore the nature of ethical practice, one of the three core inter-related areas of training for the Buddha, along with training in meditation and in wisdom. We see how ethical practice has often been understood historically as having a social dimension, both in the teachings of the Buddha and later, as in the edicts of King Ashoka. We also explore some of the ways that ethical practice has been marginalized in Western Buddhist practice, with significant consequences. Then we look at the commonality of ethical guidelines in cross-religious context, with Donald telling some personal stories. Finally, we outline several ways to carry out ethical practice and then open up to discussion.
