金剛三昧經論 2.147

2.147

論曰：此是第二通彼所難。證理之心遠離生滅無始無終，故心無出入。無出入已，亦無昔日出入之心，故無出入心。去昔有出入心，入此不出入心，故言入不入故，故名為入。如是前難得善通也。

The commentary says: This is the second [part], resolving his objection. The mind that realizes principle is far removed from arising and ceasing, without beginning and without end; hence the mind has no emerging or entering. When there is no emerging or entering, there is also no past mind of emerging and entering; hence it is a mind without emerging or entering. Removing the past mind of having emerging and entering, one enters this mind of not emerging or entering; hence it says 'because it enters non-entering, it is therefore named entry.' In this way the previous objection is skillfully resolved.
