BUT! By "Achieving" this power, you have therefore not concluded your practice, because by "100,000th power", the simple Practice has become a mere component of its former self, lending itself to become smaller and smaller for every iteration of itself, resulting in the 100,000th practice attempt being naught but 1/100,000 of the original practice. To put it in perspective, If you were to half your distance from where you are now to the pencil sharpener in my 11th grade math teacher's classroom, yes, initially you would make great strides, but as time progressed, the progress you made would decrease. Eventually you would be able to reach the pencil sharpener, it's true, but you would Never. Actually. Reach. It. In that same vein, the closer you get to this great power of practice, the further you get from ever accomplishing the journey to greatness. Therefore, I submit to you, none of us have ever actually reached the level of competence we think we have, and are stuck in an endless and fallible loop of mortality, struggling against a greater, eternal, spiritual power of perfection that we cannot reach in this lifetime.
