The light that shines in the eye is really the light of the heart. The light that fills the heart is the light of God, which is pure and separate from the light of intellect and senses.
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.
