In plain words
Yaśōdā longs: "With the conch on one foot and the discus on the other, engraved on the soles, he walks on both feet, stamping their marks here and there as if drawn, pouring and pouring still more on a flood of joy already swelling; he who is coloured like the dark, cool sea, the father of Kāma: won't he walk his toddling walk?"
