In the Treta era, various events occur, including the defeat of demons by Lord Vishnu, which leads to the birth of positive and negative forces. One of the negative forces—the rise of demon dictator Ravana—plunges the universe into terror. The birth of God becomes necessary to eliminate the terror of Ravana, leading to the birth of two of the most powerful and mutually attached godsShri Rama and Hanuman, sons of Ayodhya's King Dashrath and the ape-headed King Kesari respectively. As time passes, the two meet and become close friends. Hanuman is a celibate monkey, dedicated friend, and brave warrior. Shri Ram is an ideal human being and an excellent warrior, whose love for Hanuman knows no bounds, Shri Ram asks Hanuman to perform worldly duties until the call of time. As time progresses, events described in Valmiki's Ramayan take place. During the war of Lanka, the war skills of human beings and monkeys (along with those of Shri Rama and Hanuman) lead to the end of demon warriors like Meghnad, Kumbhakarna, and Ravan. Shri Rama ultimately returns to Ayodhya, and Ramarajya comes into existence.
