大般涅槃經義記 9.141

9.141

就根力中文別有三：一知斷善根、二「如來具足知根力」下知生善根、三「佛觀眾生具善法」下通知生斷。初知斷中，有五問答相因而起。迦葉初問闡提何緣無有善法，佛答闡提斷善故無。「闡提斷善」是其總答；「眾生悉有信等五根，闡提永斷」是其別答。「以是義」下約殺顯無。

Regarding the power of faculties, the text is divided into three parts: first, knowing the severance of the roots of goodness; second, from "The Tathāgata is fully endowed with the power of knowing faculties" onward, knowing the arising of the roots of goodness; third, from "The Buddha observes that sentient beings are endowed with wholesome dharmas" onward, comprehensively knowing both arising and severance. In the first part, knowing severance, five questions and answers arise in succession. Kāśyapa first asks by what cause an icchantika has no wholesome dharmas; the Buddha answers that because an icchantika severs good, he has none. "An icchantika severs good" is the general answer; "Sentient beings all possess the five faculties such as faith, but an icchantika severs them forever" is the specific answer. From "By this meaning..." onward, he reveals their absence by reference to killing.
