Sorrow and happiness are the heresies of virtue; joy and anger lead astray from TAO; love and hate cause loss of virtue. The heart unconscious of sorrow and happiness - that is perfect virtue. One, without change - that is perfect repose. Without any obstruction - that is the perfection of the unconditioned. Holding no relations with the external world, - that is perfection of the negative state. Without blemish of any kind, - that is the perfection of purity.
ZhuangziHe who knows he is a fool is not the biggest fool; He who knows he is confused is not in the worst confusion.
ZhuangziThe effect of life in society is to complicate and confuse our existence, making us forget who we really are by causing us to become obsessed with what we are not.
ZhuangziThe bait is the means to get the fish where you want it, catch the fish and you forget the bait. The snare is the means to get the rabbit where you want it, catch the rabbit and forget the snare. Words are the means to get the idea where you want it, catch on to the idea and you forget about the words. Where shall I find a man who forgets about words, and have a word with him?
