You show someone how to do something, they do it, and presto...the fireworks fly! What I keep trying to get accross is that there are levels of occult activity. The ones that are mostly public are safe, and then you have this leap to something like Levitation, Summonning and applications out of a fantasy story that are real in their way, but to reach those levels is not easy and not guaranteed safe unless you are very careful.
Occult development beyond the more public and folk type leads to a complete overhaul of our very being. This is not what most people want. They want to be able to DO and be the same person doing it. Real development, however (as I see it), will change you and it is about BECOMING. This is a good thing when done right, but it takes a deep comittment, and there is no guarantee the outcome will be what the seeker wants, and the path what the seeker thinks it will be. It may be more and better than what the seeker thinks when they start, but along the way they will be challenged in more ways than they can imagine. They do not call such a path "walking the razor's edge" for nothing.
