淨名經集解關中疏 1.507

1.507

所以者何。憶念。昔時世尊身小有疾。當用牛乳。我即持鉢詣大婆羅門家門下立　此二略釋所以。叡曰。現身有疾者亦不可一途而論。特以淺識之流取信耳。因於如來身而起劣相故彰阿難不達使惑同眾人。淨名高呵以開法身之唱。使見形之徒悟應感難期無方莫惻。兼寄迹取乳除彼貪求。假過阿難以明小乘之劣。

"Why is this? I recall that in the past, the World-Honoured One's body was slightly indisposed, and cows' milk was needed. I then held my bowl and went to stand before the gate of a great brāhmaṇa's house." / This is the second, briefly explaining the reason. Sengrui says: The manifested body being indisposed is also something that cannot be discussed from a single perspective; it was specifically done so that people of shallow understanding would generate faith. Because of the Tathāgata's body, they gave rise to marks of inferiority; hence Ānanda was shown to lack comprehension, causing his confusion to be shared by the assembly. Jingming rebuked him loudly so as to proclaim the dharmakāya, causing those attached to physical form to realize that responsive manifestations are hard to anticipate, and their boundless nature cannot be fathomed. At the same time, by lodging a trace in begging for milk, he eliminated that [brāhmaṇa's] greed. Borrowing an error from Ānanda, he clarified the inferiority of the Lesser Vehicle.
