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.
Eyes are more accurate witnesses than ears.
The sun is new each day.
Life has the name of life, but in reality it is death.
The path up and down is one and the same.
Men that love wisdom must be acquainted with very many things indeed.
