Here is the 2-sided perspective:
"Pure light" (in an esoteric sense) is where
everything is held in common (the same) and intelligences involved are cooperative and work
together so as to act practically as a single entity. It is also associated with plentifulness.
As a
field of pure light becomes infiltrated by points of darkness, which represent division and separation (see "pure darkness" below),
everything is no longer 100% unified and is no longer our theoretical definition of "pure light," but a mix of "light" and "dark" by our
definitions. Despite being mixed with darkness, pure light still demonstrates its properties and principles through the medium shared by the mix of
energies.
Demonstrations of pure light principles acting through this mixed medium:

YOUR BODY!!!
Okay, so the definition of
pure light given about is "everything is held in common (the same) and intelligences involved are cooperative and
work together so as to act practically as a single entity."
While not everything within the space of "your body" is uniformly cooperative (wherever you decide to draw that line -- Carl Jung included the
entire external universe as part of his human subconscious), you still can't deny that the organization is impressive. Trillions of individual cells
are directly wired in to this experience you are having right now, this consciousness you are exhibiting. And if they weren't all constantly
striving to work together, you wouldn't even be able to have this experience at all! These trillions of cells are organized into body systems,
organs, blood cells, micro-structures within various organs, but they all fall under the designation of "your body" or often even "you." You
don't even have to command them to work, and they burn together in the metabolic dance 24/7/365 to keep your entire experience going anyway.
On top of these trillions of cells naturally forming together into nearly astronomical systems of organization, each cell individually consists of
many different discrete parts and systems that work together just to make the cell complete! And each part of the cell's structure, by the right
arrangement of molecules "cooperating" to form that structure (usually chains of acids)! (
But wait, there's more!!) And outnumbering all
the human cells your body has produced throughout your entire body, are the number of "good" digestive bacteria living in your digestive system.
(Look it up!)
What is the result of
all of these unnumbered discrete parts functioning together as a single, relatively astronomical entity?
It's "you."

Electromagnetic Waves, and other repetitive natural patterns
These waves are even more fundamental to all of reality than cells and molecules are. They are so dependable that their shapes are predictable with
mathematical precision. Their oscillations are symmetrical, elegant, and did I mention they're collectively one of the four fundamental forces of
nature that material science recognizes? Their presence around atomic nuclei is actually what holds molecules apart from each other with impressive
strengths, and keeps matter from passing through other matter.
A handful of basic fundamental forces like electromagnetism have led scientists to believe that a single multi-dimensional force (their coveted
unified field equation again) is creating EM, gravity, and nuclear forces simultaneously.
