In response to 'so why can't you fly?' the answer is a lack of mental discipline: after all, its hard to control your thoughts

How do you know what you claim to know? (Okay, not you, but whoever said this.) Do you have any reproducible experimental proof of whatever violation of physical laws using mental discipline?

Isn't it suspicious that undisciplined thoughts are enough to create an illusion of physical reality perfectly obeying the physical laws, but are unable to violate the laws? That sounds to me like speaking about an archer who always perfectly hits the middle of the target, but is unable to shoot the arrow outside of the target, supposedly because he is too clumsy. I mean, isn't hitting the center of the target more difficult that missing the target? Wouldn't creating a reality perfectly obeying the laws of physics all the time require more mental discipline than having things happen randomly?

I am sure there can be dozen ad-hoc explanations, I just wanted to show how it doesn't make sense.

This also implies there is reincarnation, of a sort - there is no body to die, so you just construct a new illusory reality.

So, if you get killed, your mental discipline will improve enough to let you create new reality you can't create now? Interesting...
