大方廣佛華嚴經隨疏演義鈔 68.17

68.17

疏「四因事者」，依德起用，是釋因義。德是用因。「分別為智障」者，即分別因緣相也。

Regarding the Commentary's statement, "Fourth, 'conditioned by affairs'": initiating function based on virtue explains the meaning of 'cause'. Virtue is the cause of function. "Discrimination constitutes an obstacle to wisdom" means discriminating the marks of causes and conditions.
