I really dislike violence and it's against my religion (Buddhism). I believe we can change things for the better without resorting to violence.
The Buddha himself at times took part in non-violent activism. My view is, if it can help change things for the better I think it’s worth a go.
The hard part is if it fails.
As a Buddhist I train not to get angry or to grieve. It's not easy, I frequently fail at the training, but I keep trying. I'm not saying anyone else should do this, it is just a training I have undertaken for myself and I don't judge others for not doing the same. I just concentrate on my own practise.
I saw clearly how grief was causing me unnecessary suffering. It didn't change what happened, it made me very depressed and caused me to say and do things I regretted later. I remember after my father died I became an alcoholic and I used my grief as an excuse for this. It took me a long time to break free of it. I had a sudden lightbulb moment (insight) and I saw clearly how my grief was causing me unnecessary suffering. That grief was an activity and I didn’t have to do it.
Things in this world are impermanent, they are always changing, nothing here lasts, and we are all fated to become separated from what we love, and no amount of complaining or grieving about it will bring anyone back or change what has happened in the past.
It doesn’t mean I don't care. I don’t have to be sorrowful to care. I train myself to feel compassion and try to do what I can to help other beings but without getting angry and sorrowful about it.
The goal of the Buddhist path is to liberate the mind from suffering.
Compassion doesn’t have to involve painful feelings and emotions, and often these can make things worse. This is difficult for my non-Buddhist friends to understand, and some people have got angry with me for it, but not getting angry and not grieving doesn't make me cold and unfeeling. There is still warmth there.
You don’t have to get angry to speak truth and make a difference in the world.
