“The perfect man is pure spirit. He does not feel the heat of the burning deserts nor the cold of the vast waters. He is not frightened by the lightning which can split open mountains, nor by the storms that can whip upon the seas. Such a person rides the clouds and mounts upon the sun and moon, and wanders across and beyond the four seas. Neither death nor life concern him, nor is he interested in what is good or bad!” —Chuang Tzu
