From separation doth every kind of hurt and harm proceed, but the union of created things doth ever yield most laudable results. From the pairing of even the smallest particles in the world of being are the grace and bounty of God made manifest; and the higher the degree, the more momentous is the union. “Glory be to Him Who hath created all the pairs, of such things as earth produceth, and out of men themselves, and of things beyond their ken.” And above all other unions is that between human beings, especially when it cometh to pass in the love of God.
