One of my favorite poems by Rumi on practicing mindfulness as feelings come and go. Due to old patterns of coping, we can often be in a constant state of analyzing feelings rather than creating space, curiosity, wisdom, and kindness for them as they move through us.
The Guest House
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 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 whatever comes.
because each has been sent
as a guide from beyond.
— Jellaludin Rumi,
