How does the Sun give out light?

Do you realise that we are sailing on great magnetic waves of a spiritual sea? 

Examine these waves, Herfronzo―examine them well. And I obeyed. It was a vast ocean of pure amber flame, rolling in great waves all in one direction, and that direction toward the sun, as I could now see. This is a pure magnetic sea, said Aristotle, devoid of matter, and its destination is the sun. Now the sun is not a solid globe like the earth, neither is it inhabited, and it is as black as the blackest night and is composed of pure matter, devoid of spirit―or, in other words, it is pure carbon devoid of magnetism, but as these great magnetic waves strike and penetrate it, it continually bursts into golden flame and sends forth its rays of life and light and heat. The body of the sun is a dead primary world that has yielded up its spirit countless ages ago, and that spirit retains its form, as you retain yours, and it constantly sends back great magnetic waves to the body of the sun, which causes the sun to blaze in golden glory.

―Archangel Aristotle to Angel Herfronzo
