“We live in a world that is split,” the Buddhist meditation teacher Jack Kornfield told me, “and so our psyche is split. We make money by going to work, and we take care of our bodies in the gym, and we maybe take care of our psyche a little bit in therapy, and we do the arts when we go to a concert, and we do the sacred by going to church or synagogue or mosque or something like that. They’re all in compartments, as if the sacred was somehow separate from the work that we do, or the music that we make.”
