無量壽經連義述文贊 2.102

2.102

經曰「設我得佛」至「不取正覺」者，述云：此後、漏盡位也。十信以去皆名正定聚故。言住者，通正當之言也。

On the passage from the sūtra beginning "If, when I attain Buddhahood" down to "may I not attain perfect enlightenment": The commentary says: This subsequent one is the stage of the extinction of outflows. From the ten faiths onward, all are called the definitely determined group (samyaktva-niyata-rāśi). The word "dwell" broadly signifies being squarely within it.
