And that slayer of foes was casting glances with his eyes reddened with intoxication. And the intelligent Bhima saw that mighty chief of monkeys, of huge body, lying like unto the Himalaya, obstructing the path of heaven. And seeing him alone in that mighty forest, the undaunted athletic Bhima, of long arms, approached him with rapid strides, and uttered a loud shout like unto the thunder. And at that shout of Bhima, beasts and birds became all alarmed.

In plain words: Hanuman lies there huge as a mountain, blocking the path, his eyes red as if drunk. Bhima is not afraid. He walks up quickly and gives a thunderous shout that scares all the birds and animals.
