“Moreover, you can escape or hide from an external enemy and sometimes you can even cheat the enemy. For example, if there is someone who disturbs my peace of mind, I can escape by locking my door and sitting quietly alone. But I cannot do that with anger! Wherever I go, it is always there. Even though I have locked my room, the anger is still inside. Unless you adopt a certain method, there is no possibility of escape. Therefore, hatred or anger – and here I mean negative anger – is ultimately the real destroyer of my peace of mind and is therefore my true enemy.”
