If this be thy wish, that going to Varanavata, I may destroy the insignificant sons of Dhritarashtra—even this will I immediately do. Or if this be thy wish that, that city may be ground by me with rocks, or that I may bind Duryodhana and bring him before thee, even this will I do to-day, O thou of mighty strength.’

In plain words: Hanuman offers to destroy the sons of Dhritarashtra, the Pandavas' enemy cousins, or crush their city with rocks, or tie up Duryodhana, their leader, and bring him to Bhima, all that very day.
