述曰：《瑜伽》五十六說：彼謂後想生已，是諸有情從彼天沒。故知末後必定起心。起心之時名想正生，至中有位名為生已，生已之時便從彼沒。五十九說：異生以現行、種子潤，故必起心，便從彼沒者，其想生已，方從彼沒，是此意也。非入中有方始起心，中有有心何勞彼說。

The Commentary states: Fascicle fifty-six of the *Yogācārabhūmi* states: “It means that after subsequent thought has arisen, those sentient beings decease from that heaven.” Hence we know that at the very end they necessarily arouse mind. The moment of arousing mind is named “thought is just arising”; when reaching the state of intermediate existence, it is called “having arisen”; when it has arisen, they then decease from that state. Fascicle fifty-nine states that ordinary persons moisten with active manifestation and seeds, so they must arouse mind. As for “they then decease from that state”: it is only after that thought has arisen that they decease from that state; this is the meaning. It is not that they only begin to arouse mind upon entering intermediate existence; intermediate existence already has mind, so why would that text trouble to state it?
