無量壽經連義述文贊 3.81

3.81

經曰「究竟菩薩」至「諸三昧門」者，述云：此第三、解行究滿。即六度為行，三昧為解故。有說：見諸法生即知不滅，見諸法滅即知不生，故云不生滅非也。既見法生，必知滅故。生者歸滅，一向記故。今即我法空，空故無相，無相故無願，由此不見有生滅也。

On the passage in the sūtra from "they have attained the ultimate bodhisattva" to "the gates of all samādhis": The commentary states: This third part is the culmination and fulfillment of their understanding and practice. That is, the six perfections are the practice, and the samādhis are the understanding. Some say that seeing phenomena arise and thus knowing they do not perish, and seeing phenomena perish and thus knowing they do not arise, is what is meant by "neither arising nor perishing." This is incorrect. Once one sees phenomena arise, one must know they perish. That which arises returns to perishing; this is an unequivocal determination. Here it means that self and phenomena are empty; because they are empty, they are signless; because they are signless, they are wishless; and on this basis, one does not see arising or perishing.
