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 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. The dark thought, the shame, the malice, meet them at the door laughing, and invite them in. Be grateful for whomever comes, because each has been sent as a guide from beyond.
What remain constant in every account of angels, from ancient days to the present, is that they are both messengers and companions to humans, sent from a realm beyond usual seeing. Angels appear, and in one way or another, help us, advise us, inspire us, or amaze us.
