From the Bible:

Gospel of St. John, Chapter 1:

In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

From the Bhagavad Gita, seventh Chapter:

I am the fluidity of water. I am the silver light of the moon and the golden light of the sun. I am the AUM chanted in all the Vedas: the Cosmic Sound moving as if soundlessly through the ether. I am the manliness of men. I am the good sweet smell of the moist earth. I am the luminescence of fire; the sustaining life of all living creatures. I am self-offering in those who would expand their little lives into cosmic life. O Arjuna, know Me as the eternal seed of all creatures. In the perceptive, I am their perception. In the great, I am their greatness. In the glorious, it is I who am their glory.
