法華經義記 2.11

2.11

「此是釋迦力，何故言諸佛神力耶？」解釋者言：「釋迦是諸佛之數，此則明諸佛道同之義，放一淨光照無量國，此是他方瑞相。何故舉光明？此義亦如前釋，言此光明乃非他方瑞相，但見他方瑞相要由光明，是故舉其所由也。」

"This is the power of Śākya; why does it say 'the supernatural powers of the Buddhas'?" The commentator says: "Śākya belongs to the category of the Buddhas; this clarifies the meaning that the paths of all Buddhas are identical. Emitting a single pure light illuminating immeasurable lands is an auspicious sign in other realms. Why cite the light? The meaning of this is also as explained previously: this light is not an auspicious sign in other realms, but seeing the auspicious signs in other realms necessarily depends on the light; therefore, its source is cited."
