My favorite poem from the sufi poet Rumi
This being human is a guest house,
Every morning a new arrival.
A joy , a depression, a meanness,
some momentary awareness comes
as an expected visitor.
Welcome and entertain all!
Even if they are 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.
