“My current way of teaching mindfulness is, in part, informed by this early Shingon training. I have people observe self in terms of inner mental images, mental talk, and emotional body sensation, the three sensory elements used in the Vajrayana deity yoga practice. I've created a hybrid approach. What I have people observe is derived from the Japanese Vajrayana paradigm: self = mental image + mental talk + body. But how I have people observe is derived from mindfulness, which has its origin in Southeast Asian Theravada practice.”
