大般涅槃經集解 7.94

7.94

案僧亮曰：將欲去之，必先受之，所以稟彼四禪四空行等法也。法瑤曰：詣彼師門，或諮受常倒也。僧宗曰：《維摩經》云「以無心意無受行，而悉摧伏諸外道。」斯蓋四攝之中同事攝也。

Sengliang comments: When wishing to eliminate [a doctrine], one must first receive it; therefore he received their teachings such as the practices of the four dhyānas and the four formless attainments. Fayao says: Visiting that master's door, he might have consulted and received the inversion of permanence. Sengzong says: The *Vimalakīrti Sūtra* states, 'With no mind, no thought, and no practice of reception, he completely subdued all the non-Buddhists.' This is the embrace of shared action among the four means of embracing (saṃgrahavastu).
