The student looked and pondered a patch of the Sun reflected on the water and thought, the soul must be like a patch of light shining!  And then the student thought, oh how sad if the light cannot drink anything?  It must want to drink the water! But if it does, he will no longer be a patch of light, he will be cooled and colored. 

Then he heard inspired angels voices speaking 

See beloved student how the The water feels the light as the water of itself which it cannot feel without light, and the light sees water as a substance it wants to live in.  Each gives to the other and whirls in a dance of becoming life.
