A man who has thoroughly mastered the art does not use the sword, and the opponent kills himself; when a man uses the sword, he makes it serve to give life to others. When killing is the order, it kills; when giving life is the order, it gives life. While killing there is no thought of killing, while giving life there is no thought of giving life; for in the killing or in the giving life, no Self is asserted. The man does not see 'this' or 'that'; he makes no discrimination and yet knows well what is what. He walks on water as if it were earth; he walks on the earth as if it were water. One who has attained this freedom cannot be interfered with by anybody on earth. He stands absolutely by himself.
