首楞嚴義疏注經 9.139

9.139

「阿難！不斷三業，各各有私。因各各私，眾私同分非無定處。自妄發生，生妄無因，無可尋究。」

"Ānanda, if one does not sever the three karmas, each has its private [nature]. Due to each having its private [nature], the common share of the crowd's private [karmas] is not without a fixed place. Arising spontaneously from falsity, the falsity that arises has no cause, and cannot be investigated."
