And He it is Who spread out, the earth of the body, and set therein the firm mountains, of the bones, and the rivers of the veins, and of all, of the fruits of character traits and perceptibles, He has made in it a pair, two, that is, two kinds that are opposites, such as munificence and niggardliness, modesty and shamelessness, licentiousness and chastity, cowardice and valour, injustice and justice and their like, as well as [opposing pairs such as] black and white, sweet and bitter, wholesome and putrid, heat and cold, smooth and rough and their like. He covers, with the night of the darkness of corporeal things the daylight of spiritual things, as in the covering of the spiritual faculties with their instruments and the spirit with the body. Surely in that are signs for a people who reflect, on the handiwork of God and the harmonious correspondence between His two worlds, the minor one and the major one.
