首楞嚴義疏注經 9.140

9.140

殺、盜、婬三隨人別造，名各各私。所造攸同，故云同分。業苦相對必無參差，故云定處，即所感處也。既稱為妄，云何有因？故無尋究。此即結答前文為有定處、為復自然，彼彼發業各各私受之問也。

The three—killing, stealing, and lust—are individually committed by different persons, hence called 'each has its private [nature].' That which they commit is identical, hence it says 'common share.' Karma and suffering correspond to each other without the slightest divergence, hence it says 'fixed place,' which is the place invoked [by retribution]. Since it is called 'falsity,' how could it have a cause? Therefore it cannot be investigated. This concludes and answers the earlier question about whether there is a fixed place, or whether it is spontaneous, with each bringing forth karma and privately receiving it.
