俱舍論記 3.83

3.83

「若爾順喜至一經說故」者，難。若爾，順喜受業、順捨受業亦應如是，由彼憂根相應中順，非是異熟，以與憂根一經說故。

On "If so, then karma conducive to the sensation of joy ... because they are spoken in one sūtra": Objection. If so, karma conducive to the sensation of joy and karma conducive to the sensation of equanimity should also be like this: by their being conducive in association, they would not be karmic maturation, because they are spoken in the same sūtra as the faculty of grief.
