What is the main reason behind Agni Pariksha of Sita in the Ramayana epic?
The Ramayana and the Mahabharata are magnificent epics; sages like Valmiki and Vyasa provided answers to many profound questions within them.
After the slaying of Ravana, when Rama asked for Sita to be brought to him, he specifically instructed that she be brought walking—escorted on foot.
There was a remarkable reason for this specific instruction.
Present there, alongside Rama, were not only the warriors of Lanka and Kishkindha but also numerous Vanara warriors from across Jambudvipa.
Sugriva had summoned all the kings of Jambudvipa along with their armies to search for Sita; they had all arrived and participated in the war.
None of them had ever seen Sita before; they had only heard of her but knew nothing specific about her. They had come and fought solely because Sugriva had called upon them.
When we visit another town for an event and return home, what do we do? We share everything that happened there with others. Similarly, what would these warriors say upon returning to their own kingdoms about Sitamma?
Rama wanted to ensure that no one would ever cast aspersions on Sita—who had spent a year in a foreign land—in the future. That is why he insisted she be brought on foot in full view of everyone and undergo the Agni Pravesha (ordeal by fire); subsequently, Agni Deva (the Fire God) brought her safely back and entrusted her to Rama.
Rama’s desire was for everyone present to witness this extraordinary process, greatness of Sitamma and convey it to their people upon their return. He believed that only then would the entire world come to know of Sita’s purity. He did not act merely as Rama the individual, but as an ideal king. A king's conduct must not show even a hint of impropriety; otherwise, generations will have to suffer the consequences.
Kavisamrat Sri Viswanatha Satyanarayana described Sitamma as " Anindhanagni " (Fire that requires no fuel). After all, a stick or oil is usually needed to produce a flame, isn't it? Yet, Sitamma requires no fuel; one must understand that she is an eternally blazing fire.
When a doubt regarding Dharma arises, one should examine whether there is any subtle point of Dharma involved.
Sri Rama is the one who brings bliss to the entire universe.
