All things come out of the one, and the one out of all things.
There is but one world common for those who are awake, but when men are asleep, each turns away into a world of his own.
All things come into being by conflict of opposites.
Knowing many things doesn't teach insight.
Those who are awake all live in the same world. Those who are asleep live in their own worlds.
Those who hear and do not understand are like the deaf. Of them the proverb says: "Present, they are absent."
