Big load of methods that actually worked listed here:
Pick the one/s you want to find out more about, and then use forum search on any terms, also general search engines, Wikipedia is surprisingly useful for example for researching major demons as well as all the gods and goddesses.
Make a new topic here if you still have questions after that about a specific working or entity, etc.
I did this visualisation a while ago, you could apply it to anyone you think may be influencing your internal world:
Lookup various lucky charms and protective amulets as well, such as carrying a small mirror to deflect unwanted energies, or a crystal charged to protect you, etc.
