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.
ZhuangziThe man who has some respect for his person keeps his carcass out of sight, hides himself as perfectly as he can.
ZhuangziThe Portal of God is nonexistence. All things sprang from nonexistence. Existence could not make existence existence. It must have proceeded from nonexistence, and nonexistence and nothing are one. Herein is the abiding place of the sage.
ZhuangziLove of colors bewilders the eye and it fails to see right. Love of harmonies bewitches the ear, and it loses its true hearing. Love of perfumes fills the head with dizziness. Love of flavors ruins the taste. Desires unsettle the heart until the original nature runs amok. These five are enemies of true life. Yet these are what men of discernment claim to live for. They are not what I live for. If this is life, then pigeons in a cage have found happiness!
