Yes. I’m serious. Banishing and evoking rituals had been around forever – but here’s the thing – all of those Magicians who used them were wrong. So was Aleister Crowley when he wrote about the importance and uses of pentagram rituals. See, the thing is that Magick is a game and there’s really no danger to doing it. None at all.
As KingofHearts616 conformed, the entity you’re calling upon is OK. Don’t worry about any spiritual entities that may be attracted to you by your Magick, just go for it and try to sort out any problems after the event. Recently I posted about pentagram rituals but was advised that there are stronger rituals around – conveniently, rituals the person posting wouldn’t post. So there you have it.
One advantage of an actually physical Order with a Temple is that you learn fundamentals which are important – particularly when you see the results of students who don’t worry about such fundamentals.
