Edited. We explore the nature of equanimity and how to cultivate, with Donald particularly inspired by the qualities of equanimity he found in his father Simon, with the day of the talk the 100th anniversary of Simon's birth! We look at the Pali terms for equanimity and the general qualities of equanimity: Evenness, balance, unshakability, wisdom, connection with the awakened heart, and responsiveness, linking these qualities with particular ways that we can develop equanimity. Following the talk, there is a sustained discussion of various themes and questions.
