Hence it demands the emptiness of all the faculties. And when the faculties are empty, then the whole being listens. There is then a direct grasp of what is right there before you that can never be heard with the ear or understood with the mind.
ZhuangziThe living all find death unpleasant; men mourn over it. And yet, what is death, but the unbending of the bow and its return to its case?
ZhuangziThe perfect man uses his mind as a mirror. It grasps nothing. It regrets nothing. It receives but does not keep.
ZhuangziSorrow 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.
