大般涅槃經義記 8.50

8.50

下次解釋第三句難，「如汝所言闡提有性，何故不遮地獄之罪」牒其難辭，下對釋之，明闡提中無有佛性，故不能遮三惡道苦。是義云何？果性能遮三惡道苦，因性不能。闡提有因，未有果性，為是不遮。文中初明闡提無性，「闡提無性，云何遮」下彰其不遮。

Next, he explains the objection in the third line: 'As you have said, if the icchantika possesses the nature, why does it not avert the sins of hell?' cites the words of his objection. Below, he explains it in response, clarifying that within the icchantika there is no buddha-nature [as fruition], and therefore it cannot avert the suffering of the three wretched realms. What does this mean? The nature as fruition is able to avert the suffering of the three wretched realms, but the nature as cause is unable to do so. The icchantika has the cause but does not yet have the nature as fruition; therefore it does not avert [them]. In the text, he first explains that the icchantika lacks the nature; from 'Since the icchantika lacks the nature, how could it avert...' downward, he shows that it does not avert [them].
