The trick is knowing/understanding/comprehending/realizing what it means to say, "Thy will, not mine, be done," with the "Thy" being an absolute Mystery beyond all thought of inquiry and investigation. A thing apart, about which nothing can be known or said, hunched, intuited, grasped, thought or considered. The Source, Ground and Goal of Life is Life itself, and we cannot mess with that. We cannot even honor it, much less worship it. It IS us--we ARE it-- in the most distant, unrelated, kind of way. "It" does not allow itself even to be thought about. And doesn't care at all if we think about it, because thinking about it is like a fart in a tornado-- something no one thinks about. So, "Thy will, not mine be done," is completely meaningless and totally essential, and is the Source/Ground/Goal of all we do. Our place/role is to do what needs to be done in each situation as it arises without any idea about why it needs to be done, or why we need to do it, or how we know it needs to be done, or who/what needs it to be done... "I have no say in the matter, Gibbs. It's the pirate's life for me. Savvy?" (Captain Jack Sparrow, "On Stranger Tides"). Wanting/willing/needing/knowing/understanding/etc. have nothing to do with it, with It. We belong to what, we do not know. But, we can know that much, and trust ourselves to it, and do what needs us to do what needs to be done, and it is all "Darkness within darkness, the Gateway to Mystery" (Tao Te Ching). Our will, then, is to do the will, of what, we do not know, trusting ourselves to know it when we know it, without knowing any more than that about it. Savvy?
