The use of an apple in allegory has been commented upon by others: long before we had Apple iPhones or the Beatles named their recording company Apple, this was the fruit that my Catholic school told me had been behind the temptation of Adam and Eve, and of course it was an apple that famously fell on Isaac Newton, causing him to think of gravity.

In addition to pondering gravity, anti-gravity and the three laws of motion, Isaac Newton had something to say about the Sun, and God, or the powerful Being he called the Universal Ruler:
“This most beautiful system of the Sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being...
This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont, to be called Lord God παντοκρατωρ or Universal Ruler.”
― Isaac Newton, The Principia: Mathematical Principles of Natural Philosophy

And the quote at the top of the page shows some of his ideas about the Light Body.
