The main source of power of the occult schools

Here is the main and perhaps sole source of power of the occult schools, and the arcane initiation practices such as the Hindu chart of correspondences, the Kabbalah, etc: they obtain power from their symbolic systems because they think and believe they do. Real materialism and supermaterialism, and the religious philosophy of theological materialism replaces magic devices. Godhood is evolved to in the material and supermaterial world---compared to this real and future evolution, symbolic games have limited utility.
