大方廣佛華嚴經隨疏演義鈔 74.21

74.21

疏「法與非法但假施設」者，然法非法有其三義：一者有法為法、無法為非法，上已破有無，故今非此義；二者惡法為非法、善法為法；三以相為法、以性為非法。今通此二，善惡相因亦假施設，遣相之法明性為非法，相既不存，性不安立，故法尚應捨，何況非法，性相相因亦假設耳。

Regarding the commentary's statement, "Dharma and non-dharma are merely conventional designations": dharma and non-dharma have three meanings. First, existent phenomena are dharma, and nonexistent phenomena are non-dharma; but as existence and nonexistence have already been refuted above, this is not the meaning here. Second, unwholesome phenomena are non-dharma, and wholesome phenomena are dharma. Third, characteristic is dharma, and nature is non-dharma. Here it encompasses these two: wholesome and unwholesome are mutually conditioned and are also conventional designations; in the dharma of dispelling characteristics, explaining nature serves as non-dharma. Since characteristics do not remain, nature cannot be established; hence "even dharma should be abandoned, how much more so non-dharma?" Nature and characteristics are mutually conditioned, and are also merely conventional designations.
