We live in a time when many people are engaging in spiritual practices without belonging to particular religious traditions. Moreover, scientists have built up a substantial body of research that explores their many and various tangible effects. In this episode, Rupert Sheldrake and Mark Vernon, discuss the widespread interest in practices from mediation to pilgrimage, which Rupert investigates in his new book, Science and Spiritual Practice. They ask what the science shows, how such practices can be understood, and where the engagement with spiritual experiences outside of the context of metaphysical convictions might lead.
