The sun shines by day, the moon shines by night. The warrior shines in armor, the holy man shines in meditation. But the Buddha shines resplendent all day and all night. Because he has discarded evil, he is called a holy man.
Because he is serene in conduct, he is called a recluse. And because he has renounced his impurities, he is called a renunciate. ~Buddha, The Dhammapada
