"Although you may spend your life killing, You will not exhaust all your foes. But if you quell your own anger, your real enemy will be slain"

This quote by Nagarjuna is a pointer that our true enemy lies within ourselves. It is simple to focus on external opponents and try to beat them, but this will never genuinely bring us peace. The only method to really dominate our opponents is to quell our own anger and other unfavorable feelings. This is since these feelings are the source of our suffering and can lead us to make decisions that are not in our benefit. By controlling our own feelings, we can gain control over our lives and be devoid of the suffering caused by our own anger and other unfavorable feelings. This quote is a reminder that we ought to concentrate on controlling our own emotions and not on trying to defeat external opponents, as this will never ever really bring us peace.
