首楞嚴義疏注經 4.265

4.265

「既稱為妄，云何有因？若有所因，云何名妄？自諸妄想展轉相因，從迷積迷，以歷塵劫。」

"Since it is called delusion, how could it have a cause? If it had a cause, how could it be called delusion? From various deluded thoughts mutually causing one another, from delusion accumulating delusion, it has passed through kalpas as numerous as dust motes."
