維摩經玄疏 5.129

5.129

三、方便解脫即是業道者，文殊師利云「十不善道為種」，此即緣因種，方便解脫之種也。種即是性，故《涅槃經》云「十二因緣，名為佛性」，即十二因緣三道，三道三種佛性也。

Third, that the liberation of expedient means is the path of karma: Mañjuśrī states, 'The ten paths of unwholesome action are the seed.' This is the seed of the conditioning cause, the seed of the liberation of expedient means. The seed is nature; hence the Nirvāṇa Sūtra states: 'The twelve links of dependent origination are called the buddha-nature'—that is, the three paths of the twelve links of dependent origination are the three kinds of buddha-nature of the three paths.
