In plain words
[Continuing mid-sentence from before:] ...and that gift is worth her third foot. But her fourth foot — the visible one, the sun that blazes beyond the dust — that cannot be bought by anyone, by any gift at all. How could it be? Nothing measures up to it.
Close to the Sanskrit
[Beginning mid-word, continuing the previous sentence:] '...of her,' this, the third foot, he would obtain. Now, this indeed is her fourth, visible foot: 'beyond the dust, this one that shines' — this is not attainable by anyone at all; how then could one receive [a gift equal to] this much?
