I like your essay except for the David Blaine part...
Him dressing in black has nothing to do with demons. Black is simply a color.
His emotionless expression is simply his presentation for the effects. He is trying to look as if he is in deep, deep concentration. David wants to make it seem like he is intently focused on the effects he does. The only time he acts like he's drained of energy was when he levitates, which I was never a big fan of self levitation, so I think thats bad presentation. He never refers to any "force", but he does make numerous references to the power of the mind. Every magician does at some point. If you don't believe me, buy his book, Mysterious Stranger. He basically pours his whole life of magic into the book, and he explains how incrediblly happy his feelings were when he does his magic and endurance stunts.
I'm sure you've seen the video of him go up to the homeless man and borrow his cup of coffee. Then, he visually changes the coffee into coins, which he gives to the bum, who has tears of joy in his eyes. What you didn't see, is that afterward, David let the man stay with him in his hotel for the night. David gave him a bath, some ice cream, and all of his remaining cash, which was a couple hundred dollars. He explained this in his book.
Another example was when he went to Haiti in his "Magic Man" special. In Haiti, magic and voodoo were the same thing, and people often ran away from him or were scared of him before he even showed them a trick. He was constantly explaining that it was entertainment, that it was good, and that it was not black magic, and after he performed for them, everyone had a smile on their face.
"Magic allows people to recapture their childlike wonders and strip away their defenses. Magic makes people vulnerable. That's when they're the most beautiful, because they're no longer hiding and no longer afraid."
I really look up to David Blaine a lot. And I agree with your essay. I just want you to reconsider what you wrote about him. I'm not criticizing you, just sharing my honest opinion and defending it
