In games and sports, when people jump down from a great height, what is it that protects them from hurt? It is this spirit, and they have made it their habit to call this spirit to their aid. When people throw balls to each other, and even in boxing, the receiver of the blow awakens this spirit in that part on which he receives the blow. The sportsman does not know what this spirit is, though he takes refuge in it. The mystic understands it by his meditation, also by research into metaphysics. When a person awakes from a deep sleep, the first thing that rises through his mind to his body, when the tendency of stretching and contracting comes and of twisting and turning, and of gradually opening the eyes, is this spirit; it rises, so to speak, and spreads.
