"The lost souls number in the billions and they loiter any of an infinite number of astral dimension that are frequency-related to their previous fundamental frequency."

Why billions. Why not thousands, millions or trillions.
Are there less "lost souls" than stars in this universe?
How many can dance on a pin head?
Who could count them? What is needed before anyone could count them.
And assuming they would all "sit still" so you could count them, how many could you count before it got too boring for you? Or are you going count how many per cubic meter and times that by the total volume to get an average?

"If all they knew in life was food, sex, smokes and television they will find themselves trying to fulfill these same regenerated thought forms.

All anyone truly is, is thought."

Well some people might be familiar with what a thought is, but again how do you count them?
Let's say you "meet" a thought, what can you know about it?
Is it the same thought you have met before? Is it connected to something- including to other thoughts?
If you meet "one" thought, maybe you just seeing a part of a thought, and/or maybe a thought or part of a thought changes appearances over time.

Maybe thought doesn't follow any of basic rules of this Universe. First being that you could "see it" in any way, but other things like being in one location in space-time, "following time" in any way we are familar with, etc.
Or Maybe thoughts do generally follow the rules of this universe. Maybe you have thoughts that do follow the rules and other that don't.
Are there opposing thoughts, are they similar to humans in that they have tribes, or families, or homes, or money. Do space aliens have different thoughts.
Maybe thoughts are like the human population on the planet- they move a lot, but around half live in urban area. Some are born and live their life in some isolated village, others are travel and living all over the world.
Do they have wars, do they have leaders. Is it possible to kill an idea. Do thoughts get sick? Are there viruses- is thought a virus- in that it needs some kind host [such as a living animal]?
