While it obviously wouldn't work for how you're setting up your universe, my own inclination would be to reverse the methods stated for magic and ki/psi powers - with magic reaching beyond the possible to do what is impossible, while ki users simply punch reality in the face until it submits to their will. Of course, your way you can have a wise old master or two clucking to each other about these whippersnapper mages with no sense of subtlety, twisting the world into pretzels around them where using their own flexibility to approach the problem from an angle where the world's counter-forces don't apply would work just as well.
