Yoga asana (physical postures) practices are very helpful in preparing the body for seated meditations in which the body is usually placed in an unnatural static position in which legs are folded to form a base and the back is held erect. Regardless of preparation, static sitting places certain stresses on the body. Such stresses, especially when meditation is practiced regularly, can accumulate and manifest as discomfort, pains and over time even lead to injury.
Fortunately a few simple movements can go a long way to relieve stresses and help in a transition from stillness to movement. Two postures are all it takes to stretch the arms & legs, bend the back and gradually and safely restore movement. It takes at most a minute or two and is a great gift to the body.
