大方廣佛華嚴經疏 4.26

4.26

第七「一一」下，化身自在，謂於大眾會能現無邊作用差別，皆自在故。文中二：先明廣容，謂於如來身一一毛頭，容一切剎而無障礙。無礙有二義：一以一小毛現多大剎，則一多大小無礙；二此毛多剎與彼毛多剎參而不雜，則隱顯無礙。後「各現」下，普遍，以廣容不礙普遍故，還於前毛內剎中神力調生，若廣遍十方示現種種變化三業成所作事，居然易了。

Seventh, from "in each and every" onward, [shows] the sovereignty of the transformation-body, meaning that in the great assembly he can manifest boundless differentiated operations, all because of his sovereignty. In the text there are two parts: first, it explains vast containment, meaning that at the tip of each and every hair on the Tathāgata's body, all kṣetras are contained without obstruction. "Without obstruction" has two meanings: first, manifesting many great kṣetras with a single small hair, meaning that one and many, large and small, are unobstructed; second, the many kṣetras in this hair and the many kṣetras in that hair intermingle without becoming confused, meaning that the hidden and the manifest are unobstructed. Later, from "each manifesting" onward, [explains] omnipresence: because vast containment does not obstruct omnipresence, he additionally uses supernatural power within the kṣetras inside the aforesaid hairs to tame beings; if [understood as] vast, pervading the ten directions and manifesting various transformations of the three modes of karma to accomplish what is to be done, it is easily understood.
