" The moment it is in touch with the earth, the body recognizes it. That is why spiritual people in India walked barefoot and always sat upon the ground in a posture that allows for maximum area of contact. In this way, the body is experientially reminded that it is just a part of this earth. Never should the body forget what it is. If it forgets, it will start making fanciful demands; if you constantly remind it, then it knows its place. "
