首楞嚴義疏注經 10.241

10.241

定性者，且就一期趣寂無改判為定性，實有劫數，終迴上乘。無聞僧者，不了識陰，迷為涅槃，故同此也。圓謂周遍，精謂非麁，已離行陰為諸命元，故曰圓精。稱乎妄計，故云應心。

'Fixed-nature' temporarily classifies them as fixed-nature based on their single-minded pursuit of quiescence without change; yet there are kalpas counted, and they will ultimately return to the superior vehicle. As for the 'unlearned monks,' failing to comprehend the aggregate of consciousness and mistaking it for nirvāṇa, they are identical to this. 'Perfect' means all-pervading, and 'refined' means not coarse; having already transcended the aggregate of formations to become the origin of all lives, it is termed 'perfectly refined.' Conforming to their false calculation, it is said: 'responding to the mind.'
