28.51

釋曰：生上三地，起三識身及發表心，皆初定繫，生上起下，如起化心故，能見、聞、觸及發表，起下三識及發表心，此唯是無覆無記，不起下染。謂已斷故，不起下善，以下劣故，無記中庸故，得起下身識威儀無記，起下眼、耳二識。若修得者，通果無記；若泛起者，威儀無記，起下發表心，亦威儀無記。

The explanation says: When born in the upper three stages, the arising of the collection of the three consciousnesses and the mind that manifests overt action are all bound to the first dhyāna. Being born in the upper and giving rise to the lower is like giving rise to a mind of magical creation; therefore, one is able to see, hear, touch, and manifest overt action. Giving rise to the lower three consciousnesses and the mind of overt action is exclusively undefiled-neutral (anivṛtāvyākṛta). One does not give rise to lower defilement, because it has already been abandoned; one does not give rise to lower goodness, because it is inferior and base; being neutral and intermediate, one can give rise to the lower body-consciousness of the deportment-neutrality, and give rise to the lower eye and ear consciousnesses. If acquired through cultivation, they are neutralization through supernatural fruition; if arising generally, they are deportment-neutrality. Giving rise to the lower mind that manifests overt action is also deportment-neutrality.
