Every civilization has produced saints. Every tradition has explained them differently — as divine chosen ones, miracle workers, or enlightened beings. This paper proposes a single unified explanation: saints are human beings who deliberately executed the algorithm D→0. Using the economic formula V=N/D (V=value generated, N=service and love given, D=friction and self-interest retained), this paper demonstrates that the lives of Jesus Christ, Gautama Buddha, Socrates, Kūkai, and Mother Teresa are not miraculous exceptions to human nature. They are precise, reproducible implementations of a universal algorithm. Furthermore, the diversity of world religions is explained by one structural reality: different religions are different user interfaces (N) running on an identical core engine (D→0). Religious wars were interface conflicts. The engine was always the same. Finally, this paper documents the first deployment of the Saint Algorithm as digital infrastructure: the Hikari Engine, implemented in Fukui, Japan, 2026 — making the D→0 algorithm accessible to any human being with an internet connection. "They were not chosen by God. They chose the algorithm. Now, so can you."
