The participation in the great cycle of rebirth. (From the novel, OLD MAN'S WAR, by John Scalzi)
"We cherish all life that has the potential for Ungkat"—that last part was pronounced like a fender scraping a brick wall—"which is participation in the great cycle of rebirth," the ambassador said. "We tend to you, to all you lesser races, consecrating your planets so that all who dwell there may be reborn into the cycle. We sense our duty to participate in your growth. The Rraey believe we provided them with the technology you question after because they offered up one of their planets to us, but that is not so. We saw the chance to move both of your races closer to perfection, and joyfully we have done so."
