Pema Chödrön said this quote
“ We habitually erect a barrier called blame that keeps us from communicating genuinely with others, and we fortify it with our concepts of who's right and who's wrong. We do that with the people who are closest to us and we do it with political systems, with all kinds of things that we don't like about our associates or our society. It is a very common, ancient, well-perfected device for trying to feel better. Blame others....Blaming is a way to protect your heart, trying to protect what is soft and open and tender in yourself. Rather than own that pain, we scramble to find some comfortable ground. ”
