This is an interesting topic, and yes, it is real. Rather than disappearing into metaphysical fog, I’m going to answer the OP directly and offer something that may actually be useful in practice.
Changing your beliefs sounds simple until you actually try to do it. Then shit gets real very quickly. So try this:
Write the following questions and answer them before each ritual attempt in a journal:
What do I keep assuming is true?
What do I expect the ritual to do before I even begin?
What outcome feels impossible to me?
What thoughts keep repeating every time I go to practice?
Am I actually willing to be proven wrong?
If I am proven wrong, what does that threaten in me? My identity? My certainty? My self-image?
Am I willing to do the work without clinging to a specific outcome one way or the other?
Then test it. Pick a ritual. Do it. Journal everything. Keep going. I do not care if you do 25 rituals and think nothing happened. Keep testing. Try other rituals. Keep going. Something in you wants to find out, that is a great place to start. Just dont give up.
At some point, maybe something happens that you cannot explain away so easily. Good. That is the point. You want direct experience to push against your existing beliefs hard enough that they either break, bend, or reveal themselves more clearly.
Then you get to choose. You choose what you believe. Not a book. Not a current. Not a forum poster trying to sound profound. You.
That is true freedom, true power.
This is not an overnight thing. It takes time, It takes experience. You cannot think your way through all of it. At some point, you have to do the work and let experience push back.
Take what resonates and burn the rest. Good luck!
