"This text is an Old Testament Pseudepigraphic catalog of demons summoned by King Solomon"
Just because I've stated my position on the serious side of the occult, does not mean that I practice occult rituals. I won't believe fantasy stories of the occult from the first and second centuries AD any more than I believe in Jesus' miracles. However,...
Technically, I could "create" and/or "summon" an entity like Azathoth using rituals of ceremonial magick. I don't need so-called ancient texts to do this. Many of these so-called ancient Egyptian and Jewish magical texts have a much more recent origin than they claim. I would seriously call into question something that claims to have been written by Solomon that is not recognized as such by historians. That's why they are called Pseudepigraphs. The writer, almost certainly not Solomon, hoped to get credibility (and money?) by attaching the name of the famous king to his work.
Back to our example, Azathoth. This "demonic" entity comes from fictional works by H. P. Lovecraft. If I performed ceremonies to summon it, Azathoth could then become very real, to me. In fact, I would be willing to bet that there are quite a few fans of Lovecraftian mythology who have done this very thing. Yet, each one of them would have a different experience and perception of the entity in question, Azathoth.
If I were far enough along in the practice of magick, I might even be able to see and speak with this entity through astral projection. But, it would be a very personal experience. An unbalanced mind could lose perspective. A more rational person would see it as a way to explore sub-conscious issues and possible outcomes of actions and events. Yet it all would amount to having a conversation with myself in a lucid dream.
