The story of the fall of Kamsa begins long before the dust rose in the wrestling arena of Mathura. It began on the wedding day of Devaki, the sister of Kamsa, and the noble Vasudeva. As Kamsa, driven by a rare moment of sibling affection, drove the chariot for the newlyweds, a booming, ethereal voice echoed from the heavens. The voice prophesied that the eighth child born to Devaki would be the cause of Kamsa's death. Paranoia, swift and cold, replaced Kamsa’s joy. He immediately drew his sword to slay his sister, but Vasudeva intervened, promising to deliver every child born to them into Kamsa's hands if he would spare Devaki's life. Kamsa agreed, but his fear led him to imprison the couple in a lightless dungeon, shackled in heavy iron chains.
Over the years, Kamsa’s cruelty grew as his fear intensified. One by one, he took the first six infants born to Devaki and ruthlessly ended their lives. The seventh child, Balarama, was miraculously transferred from Devaki’s womb to that of Rohini to ensure his safety. When the time came for the eighth child, Krishna, to be born, the universe itself seemed to hold its breath. In the darkness of the midnight hour, the prison doors swung open by divine will, and the guards fell into a deep, mystical slumber. Vasudeva carried the infant Krishna across the surging Yamuna River, shielded from the torrential rains by the multi-headed serpent Shesha, and reached the village of Gokul. There, he swapped Krishna with the newborn daughter of Yashoda and Nanda, returning to the cell with the girl. When Kamsa arrived to kill this eighth child, the infant slipped from his grasp, transformed into the goddess Durga, and warned him that his slayer had already been born and was safe elsewhere.
Kamsa spent the following years in a state of agitated vigilance. He sent a succession of powerful demons—Putana, Shakatasura, Trinavarta, and many others—to find and kill the child in the pastoral lands of Vraja. However, Krishna, even as a toddler, defeated every assassin sent his way. Each failure only served to sharpen Kamsa’s desperation. He eventually realized that the boy living among the cowherds was indeed the prophesied slayer. To lure Krishna and his brother Balarama into a trap, Kamsa organized a grand religious festival known as the Dhanush Yagya, a bow sacrifice, coupled with a wrestling tournament in the heart of Mathura. He sent the virtuous Akrura to invite the brothers, hoping that his elite warriors and trained war-elephants would finish what the lone demons could not.
Krishna and Balarama accepted the invitation, seeing it as the destined time to end the tyrant's reign. As they entered the city of Mathura, their presence caused a stir. They were not merely country youths; they carried an aura of divine majesty. They first encountered a washerman of the palace who refused to give them royal garments; Krishna struck him down, signaling that the old order was crumbling. They then met Kubja, a hunchbacked woman carrying sandalwood paste for the king. Touched by her devotion, Krishna healed her deformity, transforming her into a beautiful woman. Each step through the streets of Mathura was a step toward the dismantling of Kamsa’s authority.
Upon reaching the sacrificial arena, Krishna was challenged to string the mighty bow of Kamsa. To the horror of the king’s guards, Krishna not only strung the massive weapon but snapped it in two with a sound that reverberated like a thunderclap throughout the city. This was the final omen for Kamsa. He ordered the gates of the arena to be guarded by the ferocious, intoxicated elephant Kuvalayapida. As Krishna and Balarama approached the entrance, the mahout goaded the beast to crush them. Krishna nimbly dodged the elephant's trunk, pulled it by its tail, and eventually slew the creature, using its own tusks as weapons. He entered the arena with a tusk resting on his shoulder, his clothes stained with the blood of the beast, looking more like a seasoned warrior than a boy.
The arena was packed with thousands of spectators, including the nobility of Mathura and the common folk who had suffered under Kamsa’s taxes and terrors. In the high balcony sat Kamsa, his heart hammering against his ribs. He signaled for his champion wrestlers, Chanura and Mushtika, to begin the match. These were not ordinary men; they were giants trained in the brutal arts of combat, specifically instructed to kill the brothers. The crowd gasped at the mismatch—two slender youths against the towering walls of muscle that were the king's champions. Yet, as the match began, it became clear that the brothers were immovable. Krishna grappled with Chanura, while Balarama took on Mushtika. The air was thick with the sounds of slapping limbs and heavy breathing. With a sudden surge of strength, Krishna swung Chanura around and dashed him against the ground, ending his life. Balarama followed suit, crushing Mushtika with a single, powerful blow. The remaining wrestlers fled in terror.
