I’ll tell you how I got started in magick. Then you can decide if you want to try some of the methods, or if you want to go down a different route. I did start with meditation, and that type of thing. But magick became necessary for me around 2013.
I started with the New Avatar Power book - it’s not the best book for beginners imo. I struggled with it, but also with self-discipline.
Eventually I discovered the Gallery of Magick books (look up Damon Brand, Gordon Winterfield, Zanna Blaise, and Adam Blackthorne). So I learned to do the rituals in their books. Much easier, and more beginner friendly.
I still struggled a bit until I discovered the Abraham Hicks teachings (Esther and Jerry Hicks). I have all of their books, and they have plenty of free videos on YouTube. I applied their teachings every day. It took me a couple of years to see consistent improvement. But it was worth it. Once that happened, results from using magick improved, and are still improving. It required a complete change of mindset (how complete depends on where you’re at now, belief/mindset-wise).
Now I work from some of E.A.'s books.
As for getting yourself into the trance state required - it’s easy enough. Try learning how to self-hypnotise. It will teach you some good techniques for getting yourself into trance state. I picked up Powerful Mind Through Self-Hypnosis by Cathal O’Briain. Excellent book and learned from that how to get myself into a trance state.
I also recommend Ben Woodcroft’s books which are similar to the GoM books.
I suggest that it’s a step-by-step process. Learn to petition spirits. Then learn to evoke. Learn to crawl, then walk, then run. It didn’t happen quite that way for me because of my circumstances, but ideally, that’s what I recommend.
PS I use the banishing ritual from Kingdoms of Flames. It’s effective. Use a burn bowl, place it at the centre of your home, fill it with water, put a black pillar candle in it, add salt around it, then banish using the incantation from KoF in the room you’re doing rituals in - if necessary, recite it in every room in your home. The candle set-up acts as a portal that pulls all unwelcome/hostile spirits through it. Blow the flame out after you’re done reciting the incantation. I do it every day. The GoM also teach a banishing method. And there are plenty more methods. Just find one that you feel comfortable with, and use it twice daily.
