96.16

無所希望經云。時舍利弗。知諸眾會心之所念。即時告此諸比丘言。仁等何故發於斯言。吾等之身。從今已往。無佛世尊。因從異學。出為沙門。時諸比丘。報舍利弗。吾從今始敬事六師。一切所歸。為一相耳。不倚六入。是以不見若干種師。不想出家沙門也。釋曰。倚六入而為差。妄分邪正。歸一相而為本。彼我雙亡。如是解者。可謂真出家矣。

The Nirapekṣa Sūtra says: “At that time, Śāriputra, knowing the thoughts in the minds of the assembled multitude, immediately addressed these monks, saying: ‘Venerables, why do you utter these words: “From this day forward, our bodies have no Buddha, the World-Honoured One; we follow non-Buddhist teachers and renounce the world to become śramaṇas”?’
At that time, the monks answered Śāriputra: ‘From this day forward, we respectfully serve the six teachers. That to which all return is simply the single characteristic. Not relying on the six sense entrances, we therefore do not see diverse kinds of teachers, nor do we conceive of renouncing the world to become śramaṇas.’”
Exposition: Relying on the six sense entrances creates difference, falsely distinguishing the heterodox and the orthodox. Returning to the single characteristic as the source, both other and self are extinguished. One who understands like this may be called truly renouncing the world.
