Rumi's mystical poetry often helps me regain perspective on life. In this poem, I love his notion that being human is like being a "guest house." Unexpected visitors occasionally show up and stay for a while, including some you'd really like to throw out!
Welcoming them and learning what they may have to teach you, or where they may lead you, isn't always easy. But in my experience, it always pays off — if for no other reason than it hastens the day of their departure!
