We begin by remembering the three core methods of training given by the Buddha (wisdom, meditation, and "ethics"), and their interrelationship. We reflect on how ethics has often been marginalized in Western Buddhism (and at times in Asian Buddhism). We then look in depth at the first lay ethical precept, non-harming, first in terms of the core teachings of the Buddha, and its centrality in the earlier Indian traditions of the Vedas. We examine some of the more "outer" dimensions of practicing non-harming, seeing how, with mindfulness and strong intentions, we can bring non-harming into our daily lives, including in our speech and communication. We then look at the more "inner" dimensions of practicing non-harming, looking in particular at how harming ourselves or others typically comes out of our own pain, so that practicing with pain (and the teaching of the Two Arrows) is central. The talk is followed by discussion.
