23.155

論「即二聖者至趣初果故」，具縛斷五品來十五心中名初果向，向初果故。

On the passage of the treatise from "These two noble ones" to "because they are tending toward the first fruit": Those who, being fully bound, have abandoned up to five categories [of defilement], are designated during the fifteen minds as 'approaching the first fruit', because they are tending toward the first fruit.
