Meaning

Knowing, by Brahma's own boon, that he could free himself from the binding weapon whenever he chose, heroic Hanuman let the demons tie him with rope so he might meet Ravana face to face -- then set fire to the whole of Lanka, sparing only the place where Sita stayed, and returned to bring Rama the good news.
