Light of reason, Light of God.

Bismi'llah ar-Rahman ar-Rahim...for the sake of Prophet Muhammad saws and Sheikh Nazim may Allah protect his secret.

The light of God is an ornament of wisdom.That is the meaning of "light upon light."The light of reason draws toward the earth.The light of God carries you aloft.Things of reason are of the lower world.The light of God is an ocean,reason merely a dewdrop.
- Rumi, "Mathnawi"
