One day, Rama decided to perform an Ashwamedha Yajna (horse sacrifice). He spoke to Lakshmana about this and told him to invite Sages Vashishtha, Vamadeva, Javali, and Kashyapa. Maharshi Vashishtha was head priest of the yajna and instructed Bharata, Lakshmana, and Shatrughna to prepare for the event. When all the preparations were complete, invitations were sent to sages, saints, and Brahmins to participate in the yajna.
The yajna could not be successful without the presence of both husband and wife. Since Sita was absent, her gold statue was placed on Rama's left side. The Ashwamedha Yajna was inaugurated by chanting holy Vedic mantras. An excellent specimen of a black horse was decorated with jewellery. After Rama was satisfied that all the requisite rituals were completed, he freed the horse. He told Lakshmana and the priests associated with the yajna to pursue the horse so that all the rituals would be performed properly. He himself went to the Naimisha forest, where a huge altar had been built for the Ashwamedha Yajna.
Several kings had come to the Naimisha forest for the yajna. Rama presented them with gifts, delicious food, and beautiful clothes. Bharata and Shatrughna arranged amenities and entertainment for the guests. Sugriva and the other monkeys served the Brahmins, while Vibhishana and his demon attendants served the sages. The yajna went on for a year.
The yajna was conducted beautifully, pleasing everyone in attendance. They unanimously declared that such a yajna had never been performed before and would not be undertaken again. Even the gods in Svarga had never experienced such an event. Brahmins and beggars received generous gifts and money, leaving everyone satisfied and full of praise for the yajna.
Famous sages commended Rama for his sacrifice and penance. Maharshi Valmiki and his students also attended the yajna. Valmiki foresaw that this yajna would provide Lava and Kusha the opportunity to meet their father, Rama. In a dramatic turn of events, Rama would meet and recognize them.
