大般涅槃經義記 6.308

6.308

下明如來為說所以，先問、後解。解中，初明為息餘人譏謗故說，佛若不說，餘人當言佛無慈悲；後明為益闡提故說，於中初明為令生善，「譬如」已下令出三塗。就生善中，初明闡提生善不同，佛為說法；「復有二」下舉根不同，成生有異。前中先舉，次列兩名。下明如來為之說法，汎論闡提具有三種：一者上品，現聞經法微能生信；二者中品，現聞經法不信不謗，遠能發生未來善根；三者下品，現聞不信，誹謗不受。

Below, he explains the reason why the Tathāgata preaches for them, first asking and then explaining. In the explanation, first he explains that he preaches to quell the slander and criticism of others: if the Buddha did not preach, others would say that the Buddha lacks compassion; afterward he explains that he preaches to benefit the icchantika, wherein he first explains that it is to cause good to arise, and from "For example..." onward, to cause them to escape the three wretched realms. Regarding causing good to arise, first he explains that icchantikas give rise to good differently, and the Buddha preaches the Dharma for them; from "Furthermore, there are two..." onward, he adduces differences in faculties to establish that their arising [of good] is distinct. In the former, he first adduces and then lists two names. Below, he explains that the Tathāgata preaches the Dharma for them: speaking broadly, there are three grades of icchantikas: first, the superior grade, who presently hearing the sūtras and Dharma can faintly produce faith; second, the middling grade, who presently hearing the sūtras and Dharma neither have faith nor slander, and can distantly give rise to future wholesome roots; third, the inferior grade, who presently hearing do not believe, and slander and do not accept.
