大方廣佛華嚴經隨疏演義鈔 17.37

17.37

疏「二現相品」下，明佛果無涯大用分者，〈現相品〉大用在義可知。普賢三昧言大用者，同加普賢不來而至，一多延促皆無礙故，毛光讚德無不周故。成就華藏，皆說如來遍淨法界、遍應剎海，令依正相入、塵含法界，皆無涯大用也。

Regarding the Commentary's statement, 'Second, the Manifestation of Characteristics Chapter' downward, clarifying the Section on the Boundless Great Function of the Buddha Fruition: The great function in the 'Chapter on the Manifestation of Characteristics' is clear in its meaning. As for the great function in Samantabhadra's samādhi: the shared empowering of Samantabhadra arriving without coming, the one and the many, the extended and the brief, all being unobstructed, and the hair-tip rays praising virtue leaving nothing unreached. Accomplishing the Lotus Treasury—all speak of the Tathāgata completely purifying the dharmadhātu and universally responding throughout oceans of lands, causing environment and person to mutually interpenetrate, and dust specks to contain the dharmadhātu—all of these are the boundless great function.
