“The yogi conquers the body by the practice of asana and makes it a fit vehicle for the spirit. He knows that it is a necessary vehicle for the spirit. Soul without a body is like a bird deprived of it’s power to fly. They yogi does not fear death, for time must take its toll of all flesh. He knows that the body is constantly changing and is affected by childhood, youth, and old age. Birth and death are natural phenomena but the soul is not subject to birth and death. As a man casting off worn-out garments takes on new ones, so the dweller within the body casting aside worn out bodies enters into others that are new.” ~BKS Iyengar
