大般涅槃經集解 63.77

63.77

案僧亮曰：上云佛性是常，無有三世；又云佛性未來當見。此前後相食，則常義未顯，故以空徵之也。智秀曰：第五翻，有兩句難：第一責性非三世，不應復云未來；第二責既有慈愛，豈容非善也。

Sengliang comments: Above, it was said that buddhadhātu is permanent and has no three times; yet it was also said that buddhadhātu will be seen in the future. These earlier and later statements contradict each other, so the meaning of permanence is not yet clear; hence he interrogates it using emptiness. Zhixiu comments: The fifth round contains two objections: first, challenging that since the nature is not of the three times, it should not be spoken of as future; second, challenging that since there is benevolence and love, how could it not be good?
