The Ashvamedha Yagna is a significant event in the epic Ramayana, which was performed by Lord Rama after his victorious return from Lanka. The story goes as follows: After the defeat of Ravana and the successful rescue of Sita, Lord Rama returned to Ayodhya and was crowned as the king. His rule, known as Ram Rajya, was marked by peace, prosperity, and righteousness. However, Rama was still troubled by the criticism Sita faced from his subjects about her chastity, due to her long captivity under Ravana. To prove her purity, Sita underwent the Agni Pariksha (trial by fire) and came out unscathed, proving her innocence. However, the gossip among the people of Ayodhya continued. To cleanse the negative aura and to establish dharma, Rama decided to perform the Ashvamedha Yagna, a grand horse sacrifice. According to the ritual, a consecrated horse would be let loose to wander freely and it was to be followed by Rama's army. If the horse entered a kingdom unopposed, it meant that the kingdom accepted the supremacy of the king performing the yagna. The horse was let loose and it roamed freely from one kingdom to another, all of which accepted Rama's supremacy. However, trouble arose when the horse entered the hermitage of sage Valmiki, where Sita was living in exile with her two sons, Luv and Kush, who were unaware of their royal lineage. Luv and Kush captured the horse, seeing it as a challenge to their mother's honor. When Rama's soldiers came to retrieve the horse, the young boys defeated them. Even Rama's brothers, Lakshmana, Bharata, and Shatrughna, were unable to defeat them. Finally, Rama himself had to confront them. During the confrontation, sage Valmiki intervened and revealed the true identities of Luv and Kush as Rama's sons. This revelation brought joy and sorrow to Rama. He was overjoyed to find his sons but was also saddened by Sita's continued exile. Sita, to finally prove her chastity to the world, asked Mother Earth to take her back if she had been faithful to Rama. The earth split open and Sita was taken back, leaving Rama and his sons behind. After this, Rama completed the Ashvamedha Yagna successfully, establishing his supremacy and the glory of his rule. However, he continued to rule with a golden statue of Sita by his side, living the rest of his life in her memory.
