This being human is a guest house. Every morning a new arrival. A joy, a depression, a meanness, some momentary awareness comes as an unexpected visitor. Welcome and entertain them all! Even if they’re a crowd of sorrows, who violently sweep your house empty of its furniture, still, treat each guest honorably. He may be clearing you out for some new delight.
— from "The Guest House" by Jalal al-Din Rumi (in The Essential Rumi, translated by Coleman Barks)
