And he was hard to be looked at even as the lightning-flash; and of coppery hue like that of the lightning-flash: and endued with the voice of the lightning-flash; and quick moving as the lightning-flash; and having his short fleshy neck supported on his shoulders; and with his waist slender in consequence of the fullness of his shoulders. And his tail covered with long hair, and a little bent at the end, was raised like unto a banner.

In plain words: Bhima sees the monkey chief. He shines and moves like lightning, with a short thick neck, broad shoulders, a slim waist, and a long hairy tail raised high like a flag.
