When you stand with your back to the sun, your shadow is before you; but when you turn and face the sun, then your shadow falls behind you.
Plato wrote that we live in a shadow world, where we confuse the shadow of ourselves with reality. This is the Nafs, the false ego, which stands in the light before God, causing, so to speak, a spiritual eclipse.... The Nafs turns us from the One to the many, enticing us with the things of this world. Then man attaches himself to one thing after another, which brings, at best, momentary satisfaction. Through his spiritual practices the Sufi learns to chain the Nafs, to perceive that it is only a shadow of reality; and finding the sun of truth within his being, looking upon it, one is no longer aware of the shadow.
