大方廣佛華嚴經疏 30.36

30.36

Fourth, next, vowing that one's practice accords with the dharmadhātu, accomplishing the above mind being pure and untainted and wisdom being autonomous. Because movement tallies with the dharmadhātu, there is no defilement; hence at the end it says: "Never losing or destroying all pure practices." This chapter is mostly identical with the dharmadhātu of noumenon. As wisdom arises relying on noumenon, it therefore equals the dharmadhātu; the rest can all be inferred from this, which is the meaning of dedicating toward the limit of reality (bhūta-koṭi).
