俱舍論頌疏論本 6.13

6.13

The commentary explains: 'Coexistent' means existing at the same time. 'Mutually effects' explains the coexistent cause. The treatise states: 'If dharmas are mutually virile fruits (puruṣakāraphala), those dharmas are mutually coexistent causes.' The explanation says: Possessing coexistent function, what is coexistent is itself the cause, hence called 'coexistent cause'—this is a karmadhāraya compound. Or, if the fruit and cause are coexistent, it means the cause of the coexistent—this is a tatpuruṣa compound.
