I do not 'google', unless I'm searching for a website. Google and some other search engines are geared to show whatever a given company pays to have float to the top. If you really want to learn, the old fashioned way is best. Find actual sites containing books or large volumes of information regarding your subject. Do not consider your research completed until you have read plenty from at least three sources/sites/books. Actual books are the very best to learn with, even though you will have to read them in their entirety to completely grasp what is talked about. In most cases regarding the occult ( the hidden), no one source/author will have all the answers you seek, or the proper outlook to help you grasp the concept. That is why it is critical to seek many sources. Do not expect, at any point in time, to have genuine knowledge about something by reading one book, let alone one paragraph. There are no short cuts to the occult, and for good reason.
If you seek online books or literature, I suggest finding a site called 'sacred-text'. There are easily 1000 books there which will likely contain the knowledge you seek. Be advised though, one book does not at all qualify you to teach, or begin trying what you gleam from it. Read slowly, so you don't miss crucial details, and above all, do not disrespect the author by twisting their words/teachings to fit your needs, or to make you seem cool, or smarter than you really are. There is nothing more poisonous than a lie built on truth.
