The pulses are the illusions. (Representations of symbols)

What we call reality 'exists' in the pulses of light.

Catch an object between the pulses of light that bring it to your awareness and it is not there. The illusion and the pulses are the same thing.

(There are many of these pulses, of course. Here I'm simplifying it for ease of explanation.)

The sun is very closely related to physicality because it is our representation of physicality.

Go outside and look at something in sunlight. You are not looking at the object so much as looking at the sun itself.

The symbol of the sun is everywhere throughout. It is also represented in space as the primary member of our solar system (when it needs to) but is also a member of our cellular system and every physically-oriented system that we can imagine.

There is a "sun" in everything.

We have closely approximated this relationship with artificial light and continued the illusion (although the interaction with artificial light is different).

Add a new light source to your world and you have a new (somewhat different) reality.

More on this as we begin to understand it.
