Everything flows and nothing abides; everything gives way and nothing stays fixed... Cool things become warm, the warm grows cool; the moist dries, the parched becomes moist... It is in changing that things find repose.
The sun is new each day.
You won't discover the limits of the soul, however far you go.
It is better to conceal ignorance than to expose it.
Opposition brings concord. Out of discord comes the fairest harmony.
The awake share a common world, but the asleep turn aside into private worlds.
