The powerful Hanuman, however, opening his eyes partially looked at him (Bhima) with disregard, with eyes reddened with intoxication. And then smilingly addressing him, Hanuman said the following words, ‘Ill as I am, I was sleeping sweetly. Why hast thou awakened me? Thou shouldst show kindness to all creatures, as thou hast reason. Belonging to the animal species, we are ignorant of virtue. But being endued with reason, men show kindness towards creatures.

In plain words: Hanuman barely opens his eyes and smiles. He says he is sick and was sleeping peacefully, so why did Bhima wake him? Animals do not know right from wrong, he says, but humans can think, so they should be kind to all creatures.
