XXXII.  Again I thought of the sun and a ray and light.  But here again there was a fear lest people should get an idea of composition in the Uncompounded Nature, such as there is in the Sun and the things that are in the Sun.  And in the second place lest we should give Essence to the Father but deny Personality to the Others, and make Them only Powers of God, existing in Him and not Personal.  For neither the ray nor the light is another sun, but they are only effulgences from the Sun, and qualities of His essence.  And lest we should thus, as far as the illustration goes, attribute both Being and Not-being to God, which is even more monstrous.  I have also heard that some one has suggested an illustration of the following kind.  A ray of the Sun flashing upon a wall and trembling with the movement of the moisture which the beam has taken up in mid air, and then, being checked by the hard body, has set up a strange quivering.  For it quivers with many rapid movements, and is not one rather than it is many, nor yet many rather than one; because by the swiftness of its union and separating it escapes before the eye can see it.
