大方廣佛華嚴經隨疏演義鈔 69.20

69.20

Regarding the Commentary's: below "The sūtra above states...", this is the verse by Bodhisattva Bhadramati in the "Verses of Praise atop Mount Sumeru Chapter", taking the first half as what is to be countered; the latter half, "because its nature is like empty space", speaking of inexhaustibility, is the counteragent. The rest can all be known. As for why those on the grounds are discarded first, it is because they are precisely what is realized here, moving from subtle to coarse. Furthermore, adducing what is prior to the grounds afterward uses the coarse to illustrate the subtle: the coarse have not yet realized the nature, so this ought to exist; now it cannot be obtained, how much less the nature of Buddha-nature on the grounds!
