2.212

於是維摩詰以偈答曰。智度菩薩母。方便以為父。一切眾道師。無不由是生　四十二偈答文四。初四。行明眷屬。二七行明資生。三二十八行明業用。四三行結勸。此初也。內有正智外有方便法身生焉。肇曰。智為內照權為外用。萬行之所由生。諸佛之所由出故。菩薩以智為母以權為父。

Thereupon Vimalakīrti replied in verse, saying:
"The perfection of wisdom is the mother of the bodhisattva,
And upāya is the father;
Of the teachers of all the multitudes of the path,
There is none who is not born from these." There are forty-two verses of reply, with four sections in the text: first, four verses clarify the retinue; second, seven verses clarify the provisions for life; third, twenty-eight verses clarify the activities and functions; fourth, three verses conclude with exhortation. This is the first. Having correct wisdom within and expedient means without, the dharmakāya is born. Zhao says: "Wisdom is internal illumination; expediency is external function. They are that from which the myriad practices are born, and that from which all Buddhas emerge; therefore, the bodhisattva takes wisdom as mother and expediency as father."
