The Yogi conquers the body by the practice of asanas, making the body a fit vehicle for the spirit. The Yogi knows that it is a necessary vehicle for the spirit, for a soul without a body is like a bird deprived of its power to fly.
B.K.S. IYENGAR
If you can adapt to and balance in a world that is always moving and unstable, you learn how to become tolerant to the permanence of change and difference.
