The properties of numbers you are referring to is called numerology. For example, 6 has to do with Saturn, the planet of hard work and misfortune. All mainstream sources about spiritual topics, like numerology, are heavily corrupted and need to be read with extreme discretion to separate the truth from lies. Beyond what you found on the Joy of Satan website, there is a bit of information regarding numerology in some sermons by High Priestess Maxine Dietrich. The "The Holy Bible Book of jewish Witchcraft" sermon series has some information regarding numerology.

http://josministries.prophpbb.com/topic13371.html The search functions on both the Yahoo Groups and forums are poorly designed and difficult to use. If you want to perform a search through the Joy of Satan forum, it is better to use a search engine and search for something like "josministries.prophpbb.com [keywords here]." For example, if you wanted to find sermons written by High Priest Mageson on Shiva, you can search for "josministries.prophpbb.com Mageson666 Shiva." I recommend staying away from Google. Google tracks everything you do and people have been slammed with higher insurance premiums and even been visited by SWAT teams for internet searches they made. Startpage and DuckDuckGo are two search engines that do not track you.
If you want to search through the Yahoo Groups, you can narrow your search to posts made by a single person, such as High Priestess Maxine Dietritch. In order to do that, you need to:
1. Find a post written by the author, such as High Priestess Maxine Dietrich.
2. Open the thread where the post is contained. There should be a symbol of an arrow coming out of a box towards the right of the person's username. If you hover your mouse over the symbol, it will say "open message in new tab." If the symbol is not there, you can skip this step.
3. Scroll to the bottom of the page where the post ends. There should be a link titled "See more posts by [username]".
4. Click on the link. You should be taken to a list of posts made by that person.
