In the forest Rama and Lakshmana encountered Kabandha, a ravenous monster whose head was in his stomach. He grabbed anything that moved, shoveling it into his stomach-mouth.
Rama and Lakshmana sliced off Kabandha's arms. As he lay dying, the monster thanked them. "I was once a gandharva named Vishvavasu," he said, "ravenous for music, food, drink, everything. My all-consuming greed turned me into a monster, but now I am free."
When they cremated Kabandha's corpse, his gandharva form emerged. "Go to King Sugriva in Kishkindha," the gandharva told them. "The monkeys will help you."
Then he vanished into the sky.
