Lord Hanuman, Bajrangbali or Anjaneya are the different names and this is the huge character in Ramayana through whom the great search for Sita begins and the Ramayana is centered around him without which the story seems to be not worthy or no interest. The strength and ability of Lord Hanuman is not known to himself and one has to induce him or tell him about his great quality and then only get the right impetus to invoke his strength on others and eventually win the situation. And the way he approached Sita amid the fear of attacks and magic from the Ravana rakshas followers, he made the sober entry and created confidence in Sita that he can be believed.

In fact he had the strength and energy to body lift Sita and take back to Lord Rama, but he want to give the credit of eliminating the Ravana in the hand of Ram and thus have popular exit from Sri Lanka.

Hanuman is a very important figure in our mythological narrations and he is well known by his association with Lord Rama in the Rama-Ravana war which culminated in the end of Ravana, the demon king of Lanka. Our scholars have described the brevity and devotion of Hanuman for Lord Rama and it is an exemplary show of how a devotee can follow his master. The great poet Tulsidas in his epic Ramacharitmanas has beautiful narrated the deeds of Hanuman to help his master and getting victory for Rama through an army of monkeys and bears.

Hanuman is known as 'Pavan Putra' which means son of the wind. The story goes that Hanuman was born to a nymph by wind God. Even in his childhood Hanuman was very powerful and it is said that he simply mistook the sun as a red round fruit and he flew and grab it. Lord Indra tried to struck Hanuman on the jaw but Hanuman continued and then he was cursed that he would forget his special powers in his life until he is reminded of them. Many interesting stories are based on this as time to time he was reminded about his hidden powers.
