Chapter 1 says the Blessing is the formula course all fallen humanity must pass through because the Fall happened through false love, false marriage, and false lineage.
That means restoration is not random inspiration. It has a shape. What was distorted through a satanic marriage order is supposed to be reversed through a God-centered marriage order mediated by True Parents.
This note is useful because it keeps the Blessing from being reduced to romance, ritual, or even sincerity. Book 9 presents it as a structural reversal from false family into true family.
