In training ourselves as those who have left the world, we must learn to give up all forms of evil, giving up all those things which are the cause for enmity. We conquer ourselves, we don’t try to conquer others. We fight, but we fight only the defilements; if there is greed, we fight that; if there is aversion, we fight that; if there is delusion, we strive to give it up. This is the inner battle, fighting with defilements. But there are very few people who fight like this. Most people fight with other things, they rarely fight defilements. They rarely even see them. When it comes to Dhamma practice we don’t harbor resentment and enmity amongst ourselves, but instead let go of all forms of ill-will in our own actions and thoughts, freeing ourselves from jealousy, aversion and resentment. Hatred can only be overcome by not harboring resentment and bearing grudges. ~Ajahn Chah
