Yassir Chadly, a long-time friend of Donald's who is a Sufi teacher, musician, and former Olympic swimmer, originally from Morocco, is in dialogue with Donald, and then, during the last part of the session, with the whole group. We explore Yassir's background, the three main levels of practice in Sufism, practicing in Sufism with what arises in the heart, parallels between Sufi and Buddhist practice, how to make sense of how and why some act negatively in the name of a religion (we discuss Islam and Buddhism), the unity of traditions in their deep mystical expressions, and the need to work together across traditions in our current world.
