Hi,
Hmmm. Your description reads like a "how to" manual, and too technical and philosophical. I don't understand much of it. I am much more simple minded.
We live is a world of me, you, sentient beings in need of rescue, good and bad, beautiful and ugly, this and that. So long as we are alive as human beings it will be so.
In Zazen, we taste that free of me, you, good and bad, beautiful vs. ugly, this and that. Thus, a great flowing wholeness that is Beautiful as such.
Simple as that. We learn to live the above, each of the "relative" and "absolute" dancing with and as the other. In our way, we do not get lost in either alone.
We take a vow to save all the sentient beings. One way is by realizing (and getting the sentient beings to realize) that there never were really any sentient beings to save!
