Hanuman met many obstacles on the way but so great was his strength and so deep his devotion to the task ahead that nothing could stop his progress.
One of the obstacles encountered by Hanuman was the monstrous form of Surasa. She, in fact, was the naga maiden. The gods, to test the abilities of Hanuman, asked her to block his way.
Accordingly, she blocked the path of the flight and challenged Hanuman. The vanara drew in his size and became a tiny creature. Before Surasa knew what was happening, Hanuman entered her mouth and came out of her huge frame and she was outwitted.
Continuing his flight, Hanuman landed gently on the top of a peak near the great city of Lanka.
