大方廣佛華嚴經隨疏演義鈔 16.5

16.5

Regarding the Commentary's "either essence or function, or fruit or cause": these are the distinct meanings within phenomena. "Essence" is like the Prajñāpāramitā-sūtras and so forth. "Function" is like the Ṛddhipāda-sūtra and so forth. "Fruit" is like the Mahāparinirvāṇa-sūtra and so forth. "Cause" also has multiple meanings: first, causal practices, like the Samyak-pradakṣiṇa-sūtra and so forth; second, causal stages, like the Daśabhūmika-sūtra and so forth.
