大般涅槃經義記 7.7

7.7

自下第二瑠璃為問，如來酬答。於中有六：一瑠璃將來先現光相、二辨光所從、三琉璃身至設供奉佛、四問答拂遣來去之相、五問答辨法、六琉璃聞法歡喜領解。文別可知：聖化有由故先現相，相有所從故次辨之，現相須應故次身來，來相覆真故次拂遣，來為顯法故次辨法，得法稱心故須領解。

From here below is the second part: Vaiḍūrya asks questions, and the Tathāgata replies. Herein there are six: 1. Vaiḍūrya, about to arrive, first manifests the mark of light; 2. discriminating where the light comes from; 3. Vaiḍūrya's person arriving to make offerings to the Buddha; 4. the questions and answers brushing away the marks of coming and going; 5. the questions and answers discriminating the Dharma; 6. Vaiḍūrya hearing the Dharma, rejoicing, and grasping its understanding. The textual divisions can be known: The noble transformation has its cause, so he first manifests the mark; the mark has its source, so next he discriminates it; having manifested the mark, there must be a response, so next his person arrives; the marks of coming obscure the real, so next they are brushed away; his coming is for revealing the Dharma, so next he discriminates the Dharma; having obtained the Dharma to his heart's content, he must grasp its understanding.
