The following quote is from 'Heart Advice, Weekly Quotes From Pema Chodron'. (click)
"I try to practice what I preach; I'm not always that good at it but I really do try.
The other night, I was getting hard-hearted, close-minded, and fundamentalist about
something else, and I remembered this expression that you can never hate somebody
if you stand in their shoes.
I was angry at him because he was holding such a rigid view.
In that instant I was able to put myself in his shoes and I realized,
'I was just as riled up, and self-righteous and closed-minded about this as he is,
We're in exactly the same place!'
And I saw that the more I held on to my view, the more polarized we would become,
and the more we'd be just mirror images of one another----
two people with closed minds and hard hearts who both think they're right,
screaming at each other.
It changed for me when I saw it from his side,
and I was able to see my own aggression and ridiculousness."
