Sutra 2.8 (duhkhanusayi dvesah)means that aversion stems from pain. This sutra describes the root of this klesa (impediment to freedom). Aversion has been haunting me lately, especially in my home life. I have a hard time focusing my self enough to not lash out or get angry. It helps to understand where aversion is coming from, but I need to find a way to overcome it.
Aversion stems from remembering pain from the past - but what does one do with that pain, how does one process it and move on?
