form of his in which he had bounded over the main. And wishing to gratify his brother, Hanuman
assumed a gigantic body which (both) in length and breadth increased exceedingly. And that monkey of
immeasurable effulgence stood there, covering the plantain grove furnished with trees, and elevating
himself to the height reached by the Vindhya. And the monkey, having attained his lofty and gigantic
body like unto a mountain, furnished with coppery eyes, and sharp teeth, and a face marked by frown, lay covering
all sides and lashing his long tail. And that son of the Kurus, Bhima, beholding that gigantic form of his
brother, wondered, and the hairs of his body repeatedly stood on end. And beholding him like unto the

Bhima, amidst foes, my size increaseth exceedingly by its own energy.'

mountain, the son of the wind-god became bewildered.
