We first explore several important themes in metta practice: (1) how metta practice can be seen as a training in learning to “lead” with the heart; (2) ways of working with difficult experiences, such as anger, fear, and the presence of the judgmental mind, that can arise in the “purification” process connected with metta practice; (3) how metta practice opens us to our radiant depths; and (4) the nature of metta practice with the “difficult person” and its connection with forgiveness practice. Then we explore the nature of forgiveness—clarifying what it is and isn’t; distinguishing between forgiveness as an outer, interpersonal and social process, giving several examples, including from the Heiltsuk indigenous tradition and South Africa, and forgiveness as an inner practice; and identifying some of dynamics of inner forgiveness practice.
