法華義疏 5.259

5.259

列五百人復明三十子，五百人通譬五道眾生，三十子別明昔曾稟化也。所以具明通別二種眾生者，以具化二人故也。一者、別化中下根人，令識三一權實；二者、通為一切眾生、令知三界過患也。又此經令一切眾生離凡夫地復離二乘地，以說三界過患、故令物不貪三界，謂離凡夫地；後明諸子出門求車不得及等賜大車，令知二乘是空捲、一乘是真實，令離二乘地。以是因緣故具化二人也。

Listing five hundred people and further explaining thirty sons: the five hundred people generally parable the sentient beings of the five destinies, and the thirty sons specifically explain those who formerly received transformation. The reason both general and specific kinds of sentient beings are fully explained is because he fully transforms both kinds of people: first, specifically transforming people of intermediate and lower faculties to make them recognize the provisional and real of the three and the one; second, generally for the sake of all sentient beings to make them know the faults and perils of the three realms. Furthermore, this sūtra causes all sentient beings to leave the stage of ordinary persons and further leave the stage of the two vehicles; by expounding the faults and perils of the three realms, it causes beings not to covet the three realms, which is called leaving the stage of ordinary persons; later, explaining that the sons go out of the gate seeking carriages and do not obtain them, and are equally bestowed the great carriages, causes them to know that the two vehicles are an empty fist and the ekayāna is real, causing them to leave the stage of the two vehicles. For this reason, he fully transforms both kinds of people.
