You’re right, the modern occult is definitely full of fantasy escapism and self created fantasy dimensions from favorite books and movies and other horse shit
I agree with your stance that the purpose of magick is to bring the divine into the here and now. astral travel for instance should rather be a way to explore other dimensions of existence and gain insight into the nature of things an apply them here
While self-created fantasy dimensions can be distracting and limiting, astral travel can provide an avenue for true spiritual growth and understanding.
