Heaven cannot but be high. Earth cannot but be broad. The sun and moon cannot but revolve. All creation cannot but flourish. To do so is their TAO. But it is not from extensive study that this may be known, nor by dialectical skill that his may be made clear. The true sage will have none of these.
ZhuangziThe birth of a man is the birth of his sorrow. The longer he lives, the more stupid he becomes, because his anxiety to avoid unavoidable death becomes more and more acute. What bitterness! He lives for what is always out of reach! His thirst for survival in the future makes him incapable of living in the present.
ZhuangziJoy, anger, sorrow, happiness, find no place in that man's breast; for to him all creation is ONE. And all things being thus united in ONE, his body and limbs are but as dust of the earth, and life and death, beginning, and end, are but as night and day, and cannot destroy his peace. How much less such trifles as gain or loss, misfortune or good fortune?
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.
