大般涅槃經集解 6.29

6.29

案僧亮曰：向與、今奪也。昔偏執以為足，更不進求，豈非空過放逸人耶？僧宗曰：比丘既勤勤請住，佛不許住，而乃勸問。所舉之理非其境界，絕諮啟之方，乃退保所得、息進向之路。承其此念，故有空過之責。舉昔苦行，以顯大慈之難負。

Sengliang states: "Previously he granted; now he deprives. Formerly, they clung to a partial grasp and considered it sufficient, seeking no further progress—are they not people who have passed their time in vain through negligence?" Sengzong states: "The monks having earnestly requested him to abide, the Buddha did not grant their request to abide, but instead urged them to question. The principle he set forth was not their realm; lacking any way to inquire, they retreated to hold fast to what they had attained, halting the path of progress. Responding to this thought of theirs, he thus reprimands them for passing their time in vain. He cites their former austerities to show that great compassion must not be betrayed."
