In the Satipatthana sutta on the foundations of mindfulness, the first area of practice is the body. The Buddha gives us many different practices and ways to investigate the body. This talk explores these practices, beginning with the breath, but going on to other practices that we don't often teach, such as the four elements, the 32 parts of the body, and corpse contemplations. Each of these practices can be a powerful doorway to wise seeing and freedom. This talk is the first of a series of four on each foundation of mindfulness.
