Vaali started carrying Ravana under his armpit for years. Vaali defeated Ravana and tied him with his tail (carried him on his shoulders in some other versions). Vaali and Ravana then fought a fierce battle. Ravana then reached Vaali and challenged him. First Sugriva fought with Ravana and was defeated. Ravana challenged Vaali to come and fight. Hearing Narada praising Vaali, Ravana became extremely arrogant and went to Kishkinda. Ravana comes to know about Vaali and his strengths through Narada. It is said that no one could defeat Vaali in head-on battle. Already Vaali was extremely powerful with his power almost equal to 70,000 elephants. Vaali asked Brahma for a boon such that in any duel, Vaali's opponent would loses half his strength to Vaali. Vaali was granted a boon by Lord Brahma after sitting in penance. Sugrieva ran off to Rishyamook Parvat as it is the only place where Vali couldn't come because of the curse of Rishi Matang according to which if Vali set his foot on Rishyamook Hills, he would die. Sugrieva tried to explain but Vali didn't listen. Upon seeing Sugrieva act as a king, Vali thought his brother had betrayed him. However, inside the cave, Vali killed the demon and returned home. He closed the cave with a large boulder and presumed kingship over Kishkindha. When Vali did not return and he heard demonic voices from inside the cave and blood oozing from inside the cave, he, mistakenly, concluded that Vali was dead. Vali entered the cave and told Sugrieva to wait outside. And when he came forth, the demon got terrified and ran into a cave. The Disagreement ДЄccording to Ramayana, a raging demon came to the doors of Kishkindha and challenged Vali to a fight. He adds that even if the caller for the fight had been his own son Angada, he would still go to fight. This can be understood from the fact that, when Tara tried to stop him and begged him not to go to fight Sugriva, by saying that it is Lord Rama who is helping Sugriva and has come to Sugriva's rescue Vaali replied to Tara that even if he is fighting against God he cannot ignore a challenge for a fight and remain quiet. Vaali who was with his father Indra, helping them in the churning of ocean, took Tara and married her. One gem is that various Apsaras (divine nymphs) were produced and Tara was an Apsara produced from the churning of the ocean. As one myth goes, fourteen types of gem or treasure were produced from the churning of the ocean during the time of Kurma Avatar.
