The best athlete wants his opponent at his best. The best general enters the mind of his enemy. The best businessman serves the communal good. The best leader follows the will of the people. All of the embody the virtue of non-competition. Not that they don't love to compete, but they do it in the spirit of play. In this they are like children and in harmony with the Tao.
Does one scent appeal more than another? Do you prefer this flavor, or that feeling? Is your practice sacred and your work profane? Then your mind is separated: from itself, from oneness, from the Tao.
