Using only intuition to perceive the world can be a beautiful state, but it is also dangerous. I would recommend checking personal/confirmation bias, really examine your experiences, and ask if you want the world to be a certain way, or if the world truly does work that way, whether you exist and believe or not.
I have seen a lot of sigils in my day. I have never seen a single result. I want to believe, I want humans to be capable of working forces most dont percieve.. but i just have never seen a convincing argument or manifestation for its legitimacy, and I have seen a lot of mental illness in most heavy practitioners of "magic" whether it be borderline, or something schizo related. If there are such powerful forces people are regularly manipulating, how does so little manifest itself? Why has no scientific institution ever found real results? Inb4 the secret they didnt believe hard enough
