大方廣佛華嚴經疏 4.26

4.26

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.
