大方廣圓覺修多羅了義經略疏 2.87

2.87

既知生死皆由貪愛，故欲脫生死，先斷此二。遠公《報應論》云：「夫事起必由其心，報應必由於事。是故自報以觀事，而事可變；舉事以責心，而心可反。」渴者喻其至切。

Since they know that saṃsāra is entirely due to greed and craving, if they wish to escape saṃsāra, they must first sever these two. Master Yuan's Treatise on Retribution says: 'Events inevitably arise from the mind, and retributions inevitably arise from events. Therefore, examining events by way of retribution, events can be transformed; citing events to reprove the mind, the mind can be reversed.' 'Thirst' is a metaphor for its extreme urgency.
