The Guest House, by Jelaluddin Rumi

This being human is a guest house.
Each moment a new arrival.
A joy, a depression, a meanness,
a 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.
They 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 whoever comes,
because each has been sent
as a guide from beyond.
