Mischna zu Jeschijahu 32:78

He used to say: The more flesh, the more worms; The more property, the more anxiety; The more wives, the more witchcraft; The more female slaves, the more lewdness; The more slaves, the more robbery; [But] the more Torah, the more life; The more sitting [in the company of scholars], the more wisdom; The more counsel, the more understanding; The more charity, the more peace. If one acquires a good name, he has acquired something for himself; If one acquires for himself knowledge of Torah, he has acquired life in the world to come.
