The eye is a menace to clear sight, the ear is a menace to subtle hearing, the mind is a menace to wisdom, every organ of the senses is a menace to its own capacity.
ZhuangziAll existing things are really one. We regard those that are beautiful and rare as valuable, and those that are ugly as foul and rotten. The foul and rotten may come to be transformed into what is rare and valuable, and the rare and valuable into what is foul and rotten.
ZhuangziPeople live their lives, constantly surrounded by anxiety. if they live long before dying, they end up in senility, worn out by concerns: a terrible fate! The body is treated in a very harsh fashion. Courageous men are seen by everyone under Heaven as worthy, but this doesn't preserve them from death. I am not sure I know whether this is sensible or not.
