Claim. Spirit-world ancestors actively watch their descendants and wait for the conditions that allow them to descend and help; the help is reciprocal, not free — descendants must lay conditions for it.
Elaboration. SMM describes the mobilization mechanism: “Would you all like to go to the spirit world? Which is more sincere: your desire to go to the spirit world or the desire of spirit people to return to earth? From the perspective of the Principle, should you or the spirit world be more passionate? The spirit world is the realm of the archangel, and here on earth is the realm of Adam and Eve, the realm of the children… The spirits are waiting to come to help, but why are they waiting? Would they help you to build God’s Kingdom on earth or to eat well and live in comfort? They would help to build the kingdom on earth” (5.2. Spirit world mobilization and assistance, 161-226, 1987.2.15). The earth-side condition is tearful prayer for the lost: “When the force of sympathy enters you, enabling you to shed tears based on God’s heart, the entire spirit world will be mobilized” (ibid, 96-280, 1978.2.13). Ancestral cooperation is opt-in for ancestors but obligation-out for descendants.
