大方廣佛華嚴經隨疏演義鈔 44.85

44.85

疏「行謂遷流」者，《俱舍》云「造作遷流二義名行。」《雜集》云「造作相是行相，由此行故令心造作，謂於善、惡、無記品中驅役心故。」釋曰：《俱舍》二義，今取遷流，欲訶毀故。

In the Commentary, "formations mean continuous flux": the Kośa says, "The two meanings of conditioning and continuous flux are called formations." The Abhidharmasamuccayavyākhyā says, "The characteristic of volition/conditioning is the characteristic of formations; due to these formations, the mind is made to act, meaning that it impels the mind among wholesome, unwholesome, and indeterminate categories." Exposition: The Kośa has two meanings; here, continuous flux is taken because one wishes to disparage it.
