The river where you set your foot just now is gone-those waters give way to this, now this.

Man is on earth as in an egg.

Nature is accustomed to hide itself.

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.

If we do not expect the unexpected, we will never find it.

The river where you set your foot just now is gone-those waters give way to this, now this.

Nature is wont to hide herself.
