Practicing and Preaching
[Poemen] said, “Experience is good. By experience, men are tested.” He also said, “If a man preaches but does not practise what he preaches, he is like a well of water where everyone can quench their thirst and wash off their dirt, but which cannot clean away the filth and dung that is around it.”
