। ॥ ३०९ ॥
In plain words
This is the aggregate that stands higher, lifted there by the sheer weight of sattva in it. Those who know the subject have called it māyā from the beginning: pure sattva, and nothing else, is its mark.
Close to the Sanskrit
This aggregate, superior because of the preponderance of the sattva-portion, is called 'māyā' by the knowers of that, from of old — she whose sole defining mark is pure sattva.
