Zazen involves motionless cross-legged sitting, which can be challenging at first. Establishing and maintaining correct posture and breathing is the first step in practice. You will need a cushion to sit on: cushions can be either the traditional zafu or improvised (folded hogu, yoga block, etc.) A cup of tea is typically served at the beginning to facilitate the transition from motion-based training to meditation. A typical sit lasts 45 minutes, although it may be conducted in shorter blocks interspersed with taekwondo practice.. If you are not participating in the taekwondo practice please arrive early to get settled and receive instruction as necessary.
