One Ray of God

He [God] is the Sun of Knowledge. One single ray of His has illumined the world with the light of knowledge. That is how we are able to see one another and acquire varied knowledge. 

One can see God only if He turns His light toward His own face.

The police sergeant goes his rounds in the dark of night with a lantern in his hand. No one sees his face; but with the help of that light the sergeant sees everybody's face, and others, too, can see one another. If you want to see the sergeant, however, you must pray to him: 'Sir, please turn the light on your own face. Let me see you.' 

In the same way  one  must  pray  to  God:  'O  Lord,  be  gracious  and  turn  the  light  of  knowledge  on Thyself, that I may see Thy face.'
