Altruism. Empathy. Integrity. Respect. Engagement. These five psychological states are keys to living a compassionate, courageous life, according to Buddhist teacher, anthropologist, and social activist Roshi Joan Halifax. However, each has the potential to become counter-productive: altruism can become pathological, empathy can prevent you from seeing another’s situation clearly, and engagement can become an endless to-do list. In her latest book, Standing at the Edge, Roshi Halifax likens these states to ecosystems that are the most instructive when we work from their edges. Here, Roshi Joan Halifax speaks to author Sandy Boucher about how “edge states” have been vital to her work as a change-agent, and how they might help us nourish love and justice in society today.
