Looking for the History of a Word

The word is "Overstand"

The first time I saw this word it was used in a book called "The Holy Tablets" Here is how it was used:

Chapter One, Tablet 1:12
This book reads like a science fiction Bible

12 As a result, you have strayed from the original ways of the universe, and the spiritual path that lead you to your true destiny: Knowledge, wisdom, overstanding, and right reasoning called Nuwaubu.

I also saw it used by a man in a post.

From the use of the word I understand it to mean "understand".

I looked in several dictionaries and could not find anything on the word. Until I looked in Random House Dictionary. The meaning in this dictionary is: overstand=to stand over or by.

I even looked in the Oxford Dictionary of Word Histories, and found nothing.

Can someone help please?

Thank you,

AE
