俱舍論記 15.215

「若依貪生至貪濁類故」者，若依貪生身、語、意業，故契經中名為濁業。貪之與濁，類相似故，眼、目異名故。以貪釋濁，濁是因，業是果，業從彼濁因為名，故名濁業。故《正理》云「貪名濁者，謂貪現前染著所緣，是染性故。從彼生等，准前應釋。」又《婆沙》云「問：何故貪名濁？答：能染污故。如世間染色，說名為濁。」《正理》及《婆沙》一百一十四更有多解，不能具述。

"If arising dependent on greed ... because they belong to the same category as turbid greed": if bodily, vocal, and mental karma arise dependent on greed, they are therefore called 'turbid karma' in the sūtras. Greed and turbidity belong to similar categories, just as eye (yan) and eye (mu) are different names [for the same thing]. Explaining turbidity by greed: turbidity is the cause and karma is the fruit; karma takes its name from that cause of turbidity; hence it is called 'turbid karma.' Thus the Nyāyānusāra states: "Greed is called turbid because when greed manifests, it attaches with craving to the cognitive object, being of a stained nature. Production from it and so forth should be explained as before." Furthermore, the Mahāvibhāṣā states: "Question: Why is greed called turbid? Answer: Because it can stain and pollute. Just as in worldly dyeing, the color is said to be turbid." The Nyāyānusāra and fascicle 114 of the Mahāvibhāṣā provide further explanations that cannot be detailed in full.
