大般涅槃經義記 2.205

2.205

上來第一拂去形迹，自下第二拂去言迹。於中先拂盡滅言迹，「迦葉復言：我今定知如來世尊無所祕」下，拂去昔日無常言迹。前中有三：一拂去滅迹明佛善有、二迦葉領解、三如來述可。前中迦葉先問起發，後佛答之。問中「如來云何名常」呵佛說常；「如佛言」下難破佛常；「如燈滅已無有方所」，舉佛昔言；「如來亦爾，滅無所有」，推佛同喻。滅已無有，說何為常？此難同上，何勞更為？前者難佛，如來對問直解佛常，昔言未遣，故此重問。又復向前難佛非常，佛答明常，迦葉是中難佛非有，佛答明有與前意別，故復問之。

The preceding was the first part, clearing away doubts regarding bodily traces; from here below is the second part, clearing away doubts regarding verbal traces. Within this, it first clears away the verbal traces of extinction; from "Kāśyapa spoke again: 'I now definitely know that the Tathāgata, the World-Honoured One, has no secret [treasury]'" onward, it clears away the verbal traces of impermanence spoken in the past. In the former part, there are three sections: first, clearing away the traces of extinction to explain that the Buddha truly exists; second, Kāśyapa's expression of understanding; third, the Tathāgata's confirmation. In the first part, Kāśyapa first raises the question to initiate the discussion, and afterwards the Buddha answers it. In the question: "How is the Tathāgata called permanent?" rebukes the Buddha's teaching of permanence; from "as the Buddha said" onward, he challenges and refutes the Buddha's permanence; "just as when a lamp is extinguished it has no location," adduces the Buddha's past words; "the Tathāgata is also like this: extinguished and having nothing that exists," extends the Buddha's own analogy to him. If after extinction there is nothing that exists, what is spoken of as permanent? This objection is identical to the one above, so why make it again? The previous objection challenged the Buddha, and the Tathāgata in response to the question directly explained the Buddha's permanence, but his past words had not yet been dispelled; hence this repeated question. Furthermore, previously he challenged the Buddha as not permanent, and the Buddha answered explaining permanence; here Kāśyapa challenges the Buddha as not existent, and the Buddha answers explaining existence. Since the intent differs from the preceding, he asks it again.
