Read more. Never believe one source. Try things yourself and then decide what works for you.
Do spend some time learning how to maintain spiritual hygiene though. That part is real.
Sigil magik can be used with and without kabbalah an with and without enns.
Enns are from a religion called Demonolatry - if you’re using those, get a book on demonolatry and follow that system properly to understand it.
Chants, mantras and incantations are not enns - do be clear about what you mean.
As your clair-senses awaken, you’ll find out the world is packed with entities and they were always there. You can try setting up wards against randoms and lesser entities, which work well enough (search here and online for wards) but for the most part, you’ll have to get used to it. Don’t engage unless you want to.
