俱舍論記 30.79

30.79

「有作是言至能了等者」者，此下就別破中大文第二破數論師。就中，一敘宗、二正破、三通難。此即第一敘宗。數論者言：決定有我，事用必待事用者故。謂諸事用，待事用者。如天授行事用，必待天授我行是事用。天授我名者，如是識等所有了別等事用，必待所依真實我體能了等者。

Regarding "Some say... a cognizer and so forth": from here below is the second major section within the specific refutations, refuting the Sāṃkhya masters. Within this: first, recounting their tenet; second, the direct refutation; third, resolving objections. This is the first, recounting their tenet. The Sāṃkhya says: There definitely exists a self, because an activity must depend on an agent. That is, all activities depend on agents. Just as the activity of Devadatta walking must depend on the self of Devadatta who performs this activity—Devadatta being the name of the agent—likewise, all activities such as cognition by consciousness and so on must depend on a real substantial self that is their support and acts as the cognizer and so forth.
