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.
