12.224

最後生中，或生波羅門大國師家、等現、等覺者，景云：是變化身行相成道。若實報身最後生者，其身妹大生大蓮華量同法界。

Regarding the final birth, where one is born in the family of a great Brahmin royal preceptor, fully manifests, and fully awakens: Jing says: this is attaining enlightenment through the active marks of a transformation body. If it is the final birth of the real reward body, its body is exceedingly vast, born upon a great lotus flower, equal in measure to the dharma realm.
