The human spirit is more then just flesh and bone. The hybrid of human is of the divine. Even in the word "hu" meaning angelic and "man" shows us our origins are higher then just the elements we are threaded from. Indeed, life is about the realization of just this and learning to unlock all heaven on earth.
I've found that beneath our fears are knots of "selfless expression" for lack of words. Its born out of our lack of esteem for our kind, and thus we suppress our capabilities lower to suffice as a norm perhaps. We fear God; being closer to the realization of his work in us. Prodigal son symptom or something.
Think of your weakest subject. Math. Art. Biology. Multitasking. Memory. Fighting.. i dunno. There are tests to say whether one is better and certain functions then others, and that is not to skew this fact. Discouragement of any kind stunts the growth of an individual. If you could remember the times of how things were surprised without good sound reason you could comprehend, you were less prone to repeat the task if it by association delivered a negative result. I say without sound good reason because how else would we be taught without sharing sound logic of which to build on -- otherwise we'd be reinventing the colour of traffic lights all the time.
The point of this is to say that if you can drop those barriers which discourage you from performing any task, we would all be fluent functional happier people -- I hypothesize. I would go to the extent of saying this same method of realization and release is a simplified, but easy way of saying how to become absolutely unlimited in every way possible, even to the point of freeing the human spirit from the flesh completely.
