Ravana is trying to highlight truth of his might in the form of Kumbhakarna and Meghanath,
Ravana Said, O fool, your master has made a bridge of his pride with the help of monkeys whereas might of arm is an infinite ocean without a bride,
What greatness lies in crossing a small part of ocean i have won over the eight quarters of this universe is not known to you,
Why your master send ambassador to me, is he not ashamed to make terms with his enemy, look at arms if you can, which has lifted and violently shook mount kailash, then, foolish monkey, extol your master, if you can,
May lord bless all,
Thanks Please
