36.33

疏「為毒塗鼓」者，即《涅槃》第九〈如來性品〉云「復次善男子！譬如有人以雜毒藥用塗大鼓，於眾人中擊之發聲，雖無心欲聞，聞之皆死，唯除一人不橫死者。鼓合涅槃，死喻滅惑，不橫死者喻一闡提。」「終成堅種」者，即下〈出現品〉，如上頻引。

Regarding the Commentary's statement, "Acting as a poison-smeared drum": chapter nine of the Nirvāṇa [Sūtra], the "Chapter on the Tathāgata-Nature", states: "Furthermore, good sons! It is like a person who smears a great drum with mixed poison and beats it among the crowd to produce sound; even if they have no desire to hear it, all who hear it die, except for one person who does not suffer untimely death. The drum corresponds to nirvāṇa; death illustrates the elimination of afflictions; the one who does not suffer untimely death illustrates an icchantika." "Ultimately becoming an indestructible seed": this refers to the "Chapter on the Manifestation of the Tathāgata" below, as frequently cited above.
