大般涅槃經集解 5.116

5.116

案僧亮曰：皆至是處者，現同起滅處也。皆如幻相者，令其觀空，以止悲戀之亂也。以方便力者，若諸法不空涉有，不名方便，佛心不應無著也；以佛心無著，證諸法空也。諸佛法爾者，證無著是佛果也。我今受汝食者，證方便。不食而受，蓋方便之益。僧宗曰：此下訖品，第十段領解也。

Sengliang comments: "All reach this place" refers to the place of manifesting conformity with arising and ceasing. "All are like illusory appearances" causes him to contemplate emptiness, in order to stop the disturbance of sorrowful longing. "Through the power of expedient means": if phenomena were not empty and engaged in existence, it could not be called expedient means, and the Buddha's mind would not be unattached; because the Buddha's mind is unattached, it proves that all phenomena are empty. "Such is the nature of all buddhas" proves that non-attachment is the fruit of buddhahood. "I now accept your food" proves expedient means. Receiving it without eating is indeed the benefit of expedient means. Sengzong comments: From here to the end of the chapter is the tenth section, accepting understanding.
