第三辨無想等至中，云於此生中，亦入亦起者，入無心起有心，此說於定下說於果。若生於彼，唯入不起者，唯識第七略有二釋：一、初生無心中有未有心故言唯入；二云，初生有心後住無心故名為入，不爾初生本未起心云何名入，先有後無乃名入故。

Third, in discerning the attainment of non-conception, regarding 'in this life, both entering and emerging': entering is without mind, emerging is with mind; this describes the concentration, whereas below it describes the fruit. Regarding 'if born there, one only enters and does not emerge': the seventh fascicle of the Vijñaptimātratā[-siddhi] presents two brief interpretations: First, at the initial moment of rebirth in the mindless [state], there is not yet mind in the intermediate existence, hence it says 'only enters'; the second says that at the initial moment of rebirth there is mind, and later one abides without mind, hence it is named 'entering'—otherwise, if at the initial rebirth mind has never arisen, how could it be called 'entering'? Only having [mind] first and then lacking it can be called 'entering'.
