One does not judge them, form theories about them, try to control them, or attempt to change their nature in any way; one lets them be free to be just exactly what they are. 'The perfect man', said Chuang-tzu, 'employs his mind as a mirror; it grasps nothing, it refuses nothing, it receives but does not keep.”
