The phases of fire are craving and satiety.
Abundance of knowledge does not teach men to be wise.
All things are in a state of flux.
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.
Change alone is unchanging.
Man, like a light in the night, is kindled and put out.
