what768 said:All people have the power to lift their hand for example. This may not sound like a miracle because we're used to it, but it is actually "the same thing" as if we would lift some object "outside" our "body". We would be able to do this if we were more aware of our body and ourselves.
We never think about when we walk, that our feet carries us wherever we "want". We don't even "feel" anything, we are the walking itself, "we are walking".
There is nothing wrong with using any powers. As I said, it depends on how we use a power, that decides if it is evil. We all know that it is wrong to say that a person is ugly for example, and we know it is wrong to kill someone. That would be to misuse the "power" (the power of words and the physical power).
Man is an egoistic creature, because he yet thinks he can find something good for himself in this world. He does not know that this world is only for the use of the body. We know that we must think about others. It is wrong to gain something for oneself at the expense of others.
This doesn't answer the questions.
