大般涅槃經義記 3.317

3.317

下佛答中有十一偈，初七偈半對上初請，明此經法如甘、如毒；後三偈半對向後請，教入祕藏。就前段中，初四偈半正就經法明如甘露、亦如毒藥，後之三偈就人以顯。

Below, in the Buddha's answer, there are eleven verses: the first seven and a half verses address the first request above, explaining that this sūtra's dharma is like ambrosia and like poison; the latter three and a half verses address the latter request, instructing on entering the secret treasury. In the former section, the first four and a half verses directly explain, in terms of the sūtra's dharma, that it is like ambrosia and also like poison; the latter three verses reveal this in terms of persons.
