祸兮福之所倚，福兮祸之所伏。
“It is upon bad fortune that good fortune leans, upon good fortune that bad fortune rests.”
孰知其极﹖
But though few know it, there is a bourn where there is neither right nor wrong;
其无正。
[sic]
正复为奇，善复为妖。
in a realm where every straight is doubled by a crooked, and every good by an ill,
是以圣人方而不割，廉而不刿，直而不肆，光而不耀。
Therefore the Sage squares without cutting, shapes the corners without iopping, straightens without stretching, gives forth light without shining.
