When you love your enemy, you are not trying to change your enemy into something other than your enemy. When you love your enemy, you stop having an enemy. When you love your enemy, you love yourself.
If you think you have an enemy in another person, then you are barking at a mirror. Your enemy is not another person, your enemy is your hate, fear and anger. It is hard to love your hate, fear and anger, but if you love, and love, your hate, fear and anger can’t survive.
Your hate, fear and anger are lovable as they teach you how to reflect on your experience. They make you feel so uncomfortable that they make you search for their root cause. You can love them for that. If you think you have enemies, whether in you acquaintances or in your emotions, practice love.
