In plain words
Yaśōdā longs: "Like the moon's disc mirrored in the waves of the sea, the pendant gleaming on the lovely, cool face of red-eyed Māl, Kēśava, shines everywhere and sways from side to side; and water falls in drops from his little member, water that gives the fruit of a holy bath greater than the Gaṅgā with its great rising waves: won't he walk his toddling walk?"
