大般涅槃經集解 9.122

9.122

案道生曰：尚不知世善故生天，豈知歸三寶耶？僧亮曰：是加水之中小加者也。不知因修梵行者，人天近因尚不能知，況出世常因而能知耶？僧宗曰：修少梵行受少樂者，合自構而食也，如彼群賊。加水之乳，更舉第四譬也，而是凡夫，實不能知。因少梵行者，即是加水也，因名所以。既計身為常，豈達真常所以也。寶亮曰：此下釋教也。昔唱外道生天，謂言用耶見為因。今釋云非是因耶見作因，乃是昔日供養父母，有孝敬之善為因故也。外道既不知此理，豈知出生死之路，橫計顛倒以成大耶。

Daosheng comments: If they do not even know that worldly goodness leads to birth in heaven, how could they know to take refuge in the Three Jewels? Sengliang comments: These are the ones who add only a little water. As for 'not knowing that it is caused by practicing pure conduct': if they cannot even know the immediate causes of the human and heavenly realms, how could they know the permanent causes that transcend the world? Sengzong comments: 'Cultivating a little pure conduct and experiencing a little pleasure' applies to milking and consuming it themselves, like that band of thieves. 'Milk with added water' again raises the fourth parable. 'Yet these ordinary people truly cannot know it. That it is caused by a little pure conduct' is precisely the adding of water; 'cause' means the reason. Since they conceptualize the body as permanent, how could they comprehend the reason for true permanence? Baoliang comments: Below this explains the teaching. Formerly it was proclaimed that non-Buddhists are born in heaven, which was thought to take heterodox views as the cause. Now it is explained that this is not caused by heterodox views, but because in the past they made offerings to their parents and had the goodness of filial respect as the cause. Since non-Buddhists do not know this principle, how could they know the path to escape saṃsāra? They perversely conceptualize inversions to form great heterodoxy.
