All things are in flux; the flux is subject to a unifying measure or rational principle. This principle (logos, the hidden harmony behind all change) bound opposites together in a unified tension, which is like that of a lyre, where a stable harmonious sound emerges from the tension of the opposing forces that arise from the bow bound together by the string.

Couples are wholes and not wholes, what agrees disagrees, the concordant is discordant. From all things one and from one all things.

War is the father of all things.

It is hard to contend against one's heart's desire; for whatever it wishes to have it buys at the cost of soul.

It is wise to agree that all things are one.

From out of all the many particulars comes oneness, and out of oneness come all the many particulars.
