You do not see clearly the evil in yourself, else you would hate yourself with all your soul. Like the lion who sprang at his image in the water, you are only hurting yourself, O foolish man. When you reach the bottom of the well of your own nature, then you will know that the vileness was from yourself.
RumiThe light which shines in the eye is really the light of the heart.. The light which fills the heart is the light of God, which is pure and separate from the light of intellect and sense.
Rumi
