OT is what you make of it. You can even be OT without doing some OT levels. Only these things can manifest itself of which the person he himself is or can be aware. For the same reason you can only audit out (remove the barrier) these things that you can actually see. Part of this is the level of responsibility one has taken. An OT cannibal also still would make just a cannibal.
Do OT powers exist. I believe they do. I have seen people being able to do strange things. One should be aware of one thing though and that is fear. If you let fear take control then forget becoming OT.
I fully agree.
