Narrated by Kumar Varun.
Krishna traveled to Hastinapura to negotiate peace between the Pandavas and Kauravas. Despite his efforts, including advising Duryodhana to follow the path of dharma and make peace by giving the Pandavas their rightful share, Duryodhana stubbornly refused. He declared that he would not give the Pandavas even a needle-point of land. Krishna, anticipating treachery, revealed his divine form to the court, and Dhritarashtra briefly regained his sight to witness it. Realizing that peace was impossible, Krishna left Hastinapura, signaling that war was now inevitable.
