Om Swami
Why should I let go of my enmity towards someone who is against me?
Enmity has nowhere to go
Everyone is small before Kaal (time and death), so the enmity you carry has nowhere to be kept. Ask where you will keep it and for how long, and let the worry go.
So the enmity you are holding in your mind, where are we going to keep it, and for how long?
