大方廣佛華嚴經隨疏演義鈔 23.46

23.46

疏「廣有無量」者，歷事別明故。疏「或說百種」者，即五十六經，初列十門云「佛子！菩薩摩訶薩有十種無礙用。何等為十？所謂眾生無礙用、二國土無礙用、三法、四身、五願、六境界、七智、八神通、九神力、十力。」皆有「無礙用」言。下九釋一一各有十門，故成百也。

Regarding the commentary’s "Broadly there are immeasurably many": because they are explained separately with respect to particular events. On the commentary’s "Or a hundred kinds are spoken of": this is in fascicle fifty-six, which initially lists ten headings, saying, "Disciples of the Buddha! Bodhisattva-mahāsattvas have ten kinds of unobstructed functions. What are the ten? Namely, unobstructed function regarding sentient beings; second, unobstructed function regarding lands; third, dharmas; fourth, body; fifth, vows; sixth, realms; seventh, cognition; eighth, superknowledges; ninth, divine powers; tenth, powers." All contain the words "unobstructed function." The nine explanations below each have ten headings, and thus constitute a hundred.
