Although things seem to be sometimes going up and sometimes descending, sometimes slipping away, nevertheless there is a reality, the same today as in the past. It does not change, for nothing can affect it. Could we not say it is one great harmony? So why shouldn't we ask about it.
ZhuangziThe perfect man uses his mind as a mirror. It grasps nothing. It regrets nothing. It receives but does not keep.
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.
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.
ZhuangziThe hundred parts of the body are all complete in their places. Which should one prefer? Do you like them all equally? Are they all servants? Are they unable to control one another and need a ruler? Or do they become rulers and servants in turn? Is there any true ruler other than themselves?
