大般涅槃經義記 3.226

3.226

上來第一合有五句明其罪報。第二可知。第三段中「若不持戒，云何見性」正明諸罪能障解脫，「一切眾生」下明其離罪方得解脫，「九部經」下釋疑顯法。疑相云何？昔教之中不言有性，云何說言持戒見性？故今釋云：九部經中無方等故不說有性，經雖不說，理實有之，故持得見。下明受人，辯正隱邪。

The above was the first, comprising five phrases clarifying retribution for offenses. The second can be known. In the third section, "If one does not uphold the precepts, how can one see the nature?" directly clarifies that various offenses can obstruct liberation; from "all sentient beings" and below clarifies that only by separating from offenses does one attain liberation; from "nine-part canon" and below resolves doubt and reveals the Dharma. What does the doubt look like? In the teachings of the past, it was not stated that there is a nature; how can it now be said that by upholding the precepts one sees the nature? Therefore, it is now explained: because in the nine-part canon there were no vaipulya [sūtras], it did not speak of possessing the nature; although those sūtras did not speak of it, in principle it truly exists, hence by upholding [the precepts] one comes to see it. Below, it clarifies the persons who receive [them], distinguishing the correct and concealing the heterodox.
