Sugriva's final instructions were to Hanuman, the indomitable son of Vayu who could attain the unattainable and to whom the word failure had no meaning. Sugriva was convinced that Hanuman among all the monkeys would be the real achiever and the one most likely to succeed, to him he said, " You, who can traverse the earth, the heaven and the oceans are the fittest to look for Sita". The entire responsibility of the search now rested on Hanuman. Rama was happy that the mission was entrusted to some one so capable and who had inspired so much confidence in Sugriva. He gave his ring to Hanuman saying that Sita would then be sure that it was Rama who had sent him. Bowing to Rama worshipfully, Hanuman rose into the skies along with the most powerful of Vanara armies. Even as a he was leaving, Rama said, " Hanuman, I am counting on your valor and your strength to bring back Sita!"
