俱舍論疏 1.231

1.231

論「想蘊至應如受說」，第二出想蘊體也。「想能取像」者，謂取青等、男女、苦樂相狀，故名取像。

On the passage in the treatise from "The conception skandha" to "should be stated as with feeling": Second is bringing out the intrinsic nature of the conception skandha. "Conception can grasp characteristics" means grasping characteristics such as blue and so forth, male and female, pleasure and pain; therefore it is called grasping characteristics.
