大方廣佛華嚴經隨疏演義鈔 51.4

51.4

疏「初句立宗」者，即雖善修正業，而知業性空。量云：正業是有法，空有無礙是宗法，因云緣成即無性故，同喻云如幻。幻法從緣生，空有不相礙。正業從緣生，同彼幻法不相礙。

Regarding the commentary's "The first sentence establishes the thesis": this means that although one skillfully cultivates correct karma, one knows that the nature of karma is empty. The syllogistic formulation is: Correct karma is the subject (dharmin); being unimpeded between emptiness and existence is the property to be proved (sādhyadharma); the reason (hetu) is "because being established through conditions is just being devoid of intrinsic nature"; the homogeneous example (dṛṣṭānta) is "like an illusion." An illusory phenomenon is born from conditions, and emptiness and existence do not obstruct each other. Correct karma is born from conditions, and like that illusory phenomenon, they do not obstruct each other.
