In plain words
Yaśōdā longs: "Like a dark elephant calf that has thrown white dust over itself and rolled in it, Trivikrama [who measured the worlds in three strides] plays in the clean dust and sweats till he takes on a slight sheen; so that his little feet, like a lovely lotus opened in its season, may not be hurt at all as they press the ground, won't he walk his toddling walk on a cushion strewn with cool flowers?"
