大方廣佛華嚴經疏 30.47

30.47

第四迴向實際。有二十九句，皆云法界者，理事無礙法界也。皆云住者，智契即事之理，無所住故。住即入義，以安住故。法界無二，即是等義。初云無量住者，一切善根皆是所住。今以無住之住，便同法界無量。他皆倣此。

Fourth is dedication to the reality-limit (bhūta-koṭi). There are twenty-nine clauses, all of which state "dharmadhātu," referring to the dharmadhātu of the non-obstruction between noumenon and phenomena. All state "abiding," because wisdom matches the noumenon that is identical with phenomena, and there is nowhere that it abides. "Abiding" means "entering," because it securely abides. The dharmadhātu is non-dual, which is the meaning of "equality." At the beginning it states "immeasurable abiding," because all kuśala-mūlas are that in which it abides. Now, through this abiding of non-abiding, it is equal to the immeasurability of the dharmadhātu. The others are all modeled on this.
