大方廣佛華嚴經疏 50.15

50.15

三結中，物物無性，故成種智。證斯同體而起大悲，一得永常，故云相續。又只由不知無性，故教化不絕。

In the third, the conclusion: thing by thing is devoid of intrinsic nature, hence accomplishing the wisdom of all species (sarvākārajñatā). Realizing this identical essence, great compassion arises; once attained, it is eternally enduring, hence called 'continuous.' Furthermore, precisely because they do not know the absence of nature, teaching and transformation never cease.
