I own a copy of this book that I purchased a few years ago. It’s not the most “fun” book I’ve ever encountered; but it is a deeply thought out book. I don’t know exactly what the “reading level” is for this book; but I would recommended to anyone who has a moderate to high level understanding of the english language.
Here is an excerpt found on page 28 of my copy:
"Why is it Necessary to Know the Form of the Universe?
A knowledge of the structural form and function of the alchemico-organic (physical) kosmos, is key to our knowledge of the principles which must govern the organization of society in the culminating kingdom of righteousness The importance of a knowledge of universal form and function; as pertaining to the alchemico-organic kosmos, will be admitted when the mind is sufficiently amplified to comprehend the relationship of the alchemic organic macrocosm to the organo-vital macrocosm (The Grand Man) as pertaining to and comprising the universal mass of human existence"
What could be interesting as well, is the book “The Immortal Manhood”, 1902 by Koresh, furthermore it contains a glossary that explains a lot of terms (that are also used in “The Cellular Cosmogony”) in more detail.
