Often when I get angry, my therapist points out that I have "abandoned myself". It's in those moments where I'm overtly angry at somebody else for crossing my boundaries or doing something I deem as unfair. However, what often lies underneath it all is that I have left myself and I'm not standing behind myself anymore. I'm not giving myself the backing I need and also deserve. That's the moment where the anger rises; it's in reaction to my abandonment.
When I do catch it, I find it useful to explore all the subtle ways I'm blaming myself for the situation. In those instances, I often don't like myself and find it hard to bring compassion towards my own process - something I teach to my students, but invariable fail to do so myself. This process is very subtle and I have to really sit with the feelings to uncover the deeper layers of it all.
I encourage you to feel into your anger the next time it arises and feel for the ways you might be not giving yourself the support you need and deserve. Stand behind yourself no matter what! Move into your heart space and feed yourself from that place.
Yoga, well-being and mindfulness... always walk in beauty.
