俱舍論疏 24.129

24.129

論「學意未滿故至常隨遂故」，答也。有兩因：一雖暫無無漏學，學意未滿，名為有學。如行者暫息，不名已到，而名行者。二無漏學得常隨遂故，由得學法，名為有學。

On the Śāstra's statement: "Because the intent to learn is not yet complete up to because it constantly attends [them]": This is the answer. There are two reasons: First, although they temporarily lack anāsrava learning, because their intent to learn is not yet complete, they are called a learner. Just as a traveller who temporarily rests is not called one who has already arrived, but is still called a traveller. Second, because the possession (prāpti) of anāsrava learning constantly attends them, by virtue of having attained the dharmas of learning, they are called a learner.
