Rama waited in the forest during the rains, impatient to resume the search. Sugriva, now his ally, had vowed to help.
But when the rains ended, Sugriva continued to eat, drink and make merry with his wives in the palace.
"In my exile, I cannot enter the city," Rama said to Lakshmana. "You must go speak to Sugriva."
Lakshmana stormed into the palace, ready to kill Sugriva in his rage.
Ashamed, Sugriva begged Lakshmana's forgiveness and went to Rama at once. "I will send out search parties," said Sugriva. "My monkeys will scour the whole world to find your Sita."
