Math wouldn't exist without chaos. And for really complex problems, God creates special equations. Some mathematicians call those shortcuts.

I understand Mccoy’s exacting equations but if it wasn’t for God’s Grace I doubt very seriously I would be around today and definitely not have the health I’m presently blessed having. We actually can get an extension on life if we are blessed to have it and want to get rid of some of our lingering karma.
Steve, what do you mean exactly by God's grace? The law of karma is mathematical in its effects, as God intended it to be. But we know that some actions like meditation, or the direct intervention of an enlightened master can alleviate our karmic burden, that is can dampen the sleeping reaction ready to be put in motion by our previous actions when the right opportunity occurs (the so-called seeds of karma). It may even erase such reactions (the so-called burning of the seeds of karma).
But again, it's all metaphysical mathematics. A karmic seed waits to sprout, unless it's possibly burnt by proper actions. So, God's grace may be meeting Yogananda who bestowed to us kriya yoga which can actually burn some karma.
Healthwise, we may counteract previous bad karma by actuating a healthy lifestyle, which may 'burn', some dormant deleterious seeds.
painful
At the end, though, I wonder. Can a cruel murderer expect that his heinous actions be counteracted? I think not. He must necessarily reap the painful results of his heinous action, otherwise God would turn out to be unfair, arbitrary and whimsy in his laws.
