Heaven and Earth, reconciled
The "Will of Heaven" represents the Divine Will of the Creator. By contrast, the supposed "Will of Earth" represents darkness and evil. The problem is of course that the "Will of Heaven" is not completely manifested and acted upon, at least from our subjective perspective. The "Will of Earth", on the other hand, is evidenced frequently by things like happenstance, corruption, entropy, brute force. Nobody wants things that suck, but they - apparently - happen that way. The "Will of Earth", then, is an argument for the existence of true evil, each moment one fraudulent witness after another approaching and testifying to its reality. It wouldn't be believable in a perfect Creation, except on the strength of its own manifest evidence.
In short, then, what the "Will of Earth" is is the strength of manifestation, of solid, concrete reality. Of the strength to achieve, though achieve what exactly it knows not. It represents physicality and solidity of Creation... the power to manifest itself as real. It is the aspect of Creation that was... well, Created, so to speak.
By contrast, the "Will of Heaven" is Divine Will, though often unmanifested in our environment (at least within out perception). It is absolutely Perfect and desirable... but evidently, often missing or elsewhere. Unmanifest.
It becomes increasingly clear that what they each are is not two opposing things or forces, but rather two sides of the same coin. We commit the perceptual error of splitting one thing into two opposite things when we commit the conceptual error of choosing to believe that there is anything else but Divine Perfection existant anywhere. The force of that choice causes us to percieve something unified as fragmented, with each fragment imperfect and unsatisfactory: a bullying and fearful Creation manifested without Divine guidance, and a sort of talking head, absentee-father figure of our Maker. Fact is, Creation wouldn't be Creation without perfect and total Divine causation, and our Divine Maker wouldn't be perfect if there were any place in Creation that He was not wholly present in. Manifestation and Perfection, two parts of the same thing that make absolutely no sense (nor should they) when perceived as being separate. Manifestation necessarily is Perfect, and Perfection necessarily is Manifest. All perceptions to the contrary are in error; we can rejoice together in their correction. Accepting the correction by Choosing in accordance with it, and acting upon that Fact, is our great joy while we still encounter an erroneous perception of Creation. Acting and Choosing otherwise, continuing to invest in the error, is to live in a weaker, spinoff fiction of reality and to perceive things like that, but Fact always dispels fiction since it displaces what was never there. And it doesn't matter who chooses Fact, since our Nature is unified. I can dispel my Brothers' error, since my Brother is truly incapable of error. There is no opposite to this approach, either; the opposite of Choosing what exists in Eternity is to Choose something that cannot exist, and that is simply a rejection of the Nature of Creation disguised as a Choice. A rejection of Fact changes nothing, and can be dispelled (since it never was). Ultimately, then, it is simply inaction. Which makes perfect sense. The opposite of living in accordance with the Fact of Creation is to do something which does not exist. I quite literally have Everything in my favor. Or, more truly, we have Everything in our favor. Since there is no contest, there is no competition, and any argument for any kind of error is truly nothing. What an ideal circumstance to abide in Love and Fact, and affirm the True Nature of my Brother by approaching him with Love and Joy? There really isn't anything else in Creation to do, or that is worth doing, though there are many ways to express Love and Joy.
