After Ravana lost his life in the Sri Lankan war, Lord Rama was coming back to Ayothi along with his wife, Sita and brother Lakshman. They lived in Bharathwaja Maharishi's house. Sometime later, Narathar came to visit them. Lord Rama prayed to him and he was blessed by Narathar who told him that the battle of Sri Lanka has ended but there may be more problems and storms that he might have to endure. He told him that although Ravana did lose his life in the war, but there are generations of demons that still exist, who might retaliate on behalf of Ravana, their leader who was defeated in the war, He revealed to him that there were two demons that were repenting beneath the sea. He added that after they had ended their penance; they would be blessed with super powers so strong, that they could use them to bring about the demolition the world and he ordered him to destroy those demons as soon as possible. However, Lord Rama told him that he could not postpone his plan of going back to his town of Ayothi, as Bharat would take hold of the mobile suit. Rama was told by Narathar to delegate Lakshman who was his kin instead, however, Rama refused saying, Lakshman was his assistant, who never left his side, so he has to stick by his side.Then Rama asked Lord Hanuman to go and destroy the demons. Lord Vishnu even provided his 'Conch' and 'Chakra' while Goddess Sakthi provided her 'Thirusoolam', Weapons by the names of 'Bramakapalam', ' pasangusam' and 'Manthrashtakam' were provided by Lord Brahma.Lord Rama provided his archery weapons whereas, Lord Krishna provided Lord Hanuman with 'Sattai' and 'Butter' so that he could bring about the destruction of the Evil demons.Lord Hanuman has demonstrated all his capacities with ten of his hands.
