They do seem a bit extremist, but some of it makes sense.
Anytime you take a little truth and mix it with error to come up with a false conclusion, this statement is true. Then we all have self doubt, thinking that it made ‘some’ sense.
What is more natural than friggin breathing?!? These extreeme guys think this: IF you ever give any credence to something other than God, then you are giving credence to the Devil. That could be breathing, necklaces, movies, symbols, statues, words you say, etc.
Bear in mind, in their little black and white world, you do not have to be aware of any of this. You can worship the Devil and not even know there is a Devil. It is beautiful. Think of the limitless potential now of things you can say about others you do not understand.
These master you mention and their feats, are not possible because they have Qi, and you do not. It is possible because they have refined and chanelled their Qi. That is where they are different.
It is no different that others not in CMA, that refine one aspect of humanity, or combine several aspects of existing humanity, such as running a 4 minute mile, or squating 1000 lbs, or letting 3000 bees form a ball on your head. All require channelling the mind, or the mind and muscle to a point that a normal person does not.
Nobody thought breaking 4 minutes was possible. In fact doctors said it was not physically possible! Nobody could do it, no matter how fast or talented, or genetics or training. But Bannister broke 4 minute in the mile, and within six months, I think 4 others also broke 4 minutes. Suddenly, every world class miler could beat 4 minutes. Today, if you cannot break 4 minutes, you are a bum in international mile competition! Trust me, these guys get in touch with their bodies to do that kind of running.
