Great interview! I am on part two right now where they are talking about how consciousness doesn't render something unless needed. I thought of another way to explain how this is on top of the ways Tom uses to describe it. Another way you could explain this to people that don't have a good grasp on it is how we view light from our PMR perspective; You could use the example of a flashlight beam moving through pitch darkness. When watching everything within our vision on a pitch dark night, shining a flashlight, what we view that falls under the flashlight beam is clear to us, everything outside the beam of light is not clear at all. Take the flashlight beam example and look at it from an outside perspective; Imagine us as the flashlights, the beam as our field of view, and the darkness outside of the beam as the un-rendered parts of reality for a more fluid understanding.
It comes in handy flashlight in the dark. Can easily navigate through the flashlight in the dark. They may be examples of the beam. It may be part of the liquid material for understanding reality.
