Cara Mia, if that man has not separated you from the love of God, and he has not, then the only thing keeping hate of him alive is your thought about him. Only your pride keeps him in your memory. Dissolve your pride, and you dissolve your hate. To be still possessed of the hate that pain made is not intelligent. Take care. It can sap your energy to what you know to be your purpose. By being troubled about it, you have already discovered it to be unworthy of your grander aims, and that is the beginning of humility.
Inner peace is not found by staying on the surface of life, or by attempting to escape from life through any means. Inner peace is found by facing life squarely, solving its problems, and delving as far beneath the surface as possible to discover its verities and realities.
