In plain words
Yaśōdā calls: "For the sake of Sītā with the lightning-slender waist he bent the bow that has no equal till its ends curved and loosed it, so that all ten jewelled, crowned heads of the king of Laṅkā's people [Rāvaṇa] fell together: bring a stick for him of the gleaming crown! Bring a stick for him who dammed the sea!"
