大方廣佛華嚴經隨疏演義鈔 34.79

34.79

疏「漚和涉事」者，漚和俱舍羅，此云方便善巧。即肇公《宗本論》文。論云「漚和般若者，大慧之稱也。諸法實相謂之般若，能不形證，漚和功也；適化眾生謂之漚和，不染塵累，般若力也。然則般若之門觀空，漚和之門涉有。涉有未始迷虛，故常處有而不染；不厭有而觀空，故觀空而不證。是為一念之力權慧具矣。一念之力權慧具矣，好思歷然可解。」

Regarding the commentary's phrase "upāya engaging in phenomenal affairs": *upāyakausalya* (漚和俱舍羅) is translated here as skillful means (方便善巧). This is text from Master Sengzhao's *Zongben lun* (Treatise on the Fundamental Source). The treatise states: "*Upāya* and *prajñā* are designations for great wisdom. The real mark of all dharmas is called *prajñā*; the ability not to realize it directly [in personal quietude] is the efficacy of *upāya*. Adapting to transform sentient beings is called *upāya*; remaining untainted by worldly defilements is the power of *prajñā*. Thus, the gate of *prajñā* contemplates emptiness, while the gate of *upāya* engages in existence. Engaging in existence, one is never deluded about the void; hence one constantly abides in existence yet remains undefiled. Not being averse to existence, one contemplates emptiness; hence one contemplates emptiness yet does not realize [quiescent cessation]. Thus, by the power of a single thought-moment, expedient means and wisdom are both complete. The power of a single thought-moment fully possesses expedient means and wisdom—contemplate this well, and it will be distinctly clear and understandable."
