Ashtanga YogaA methodology for controlling one's own mind by linking breath with movement. This movement-breath system is called Vinyasa in Sanskrit, the language of many foundational yoga texts. Each movement, for example, reaching the arms overhead, corresponds with an inhale or exhale. This is one Vinyasa, one inhale (puraka) or exhale (rechaka), along with one movement.
