14. 'They perceive that highest indescribable pleasure, saying, This is that. How then can I understand it? Has it its own light, or does it reflect light?'

15. 'The sun does not shine there, nor the moon and the stars, nor these lightnings, and much less this fire. When he shines, everything shines after him; by his light all this is lighted .'
