俱舍論記 15.47

15.47

「三由重行至起餘無表」者，三由重行，謂起如是殷重作意，若行善時，謂淳淨信，如禮佛等；若行惡時，謂猛利纏，如捶打等。由心重故，無表續生。釋訖結言，由此三因起餘無表。

Regarding the passage "Third, due to intense action... arises other non-manifest karma": third is due to intense action, meaning generating such earnest and intense attention. When performing good, it refers to pure faith, as in paying homage to the Buddha and so forth; when performing evil, it refers to vehement defilements (paryavasthāna), as in beating and strike. Because the mind is intense, non-manifest karma continues to arise. Having finished explaining, it concludes by saying: other non-manifest karma arises from these three causes.
