In the ancient and hallowed city of Ayodhya, there once reigned a king named Sagara, a scion of the illustrious Suryavamsha or Solar Dynasty. He was a monarch of immense power and virtue, having reclaimed his father’s lost kingdom from the usurping tribes of the Haihayas and Talajanghas. Sagara was a man of great ambition, but for many years, his palace remained silent, devoid of the laughter of children. He had two wives: Keshini, the daughter of Vidarbha, and Sumati, the daughter of Arishtanemi. Seeking to ensure his lineage, Sagara performed intense penance in the Himalayas, a mountain range known as the abode of the gods. After years of austerity, the sage Bhrigu granted him a peculiar boon: one wife would bear a single son who would continue the dynasty, while the other would give birth to sixty thousand sons who would grow to be mighty warriors. Keshini chose the single son, named Asamanja, while Sumati became the mother of the sixty thousand.
As the decades passed, the sixty thousand sons of Sagara grew into a formidable force. They were strong, proud, and fiercely loyal to their father, yet their sheer numbers and physical prowess bred a sense of arrogance that bordered on tyranny. They patrolled the world with an iron fist, ensuring that no one dared challenge the authority of Ayodhya. Meanwhile, King Sagara decided to cement his status as the supreme emperor of the earth by performing the Ashvamedha Yagna, the horse sacrifice. This ritual involved releasing a consecrated horse to wander the world for a year; any territory the horse traversed was claimed by the king, unless another ruler could defeat the king’s army in battle. To complete one hundred such sacrifices would grant Sagara a status equal to that of Indra, the king of the gods.
Indra, watching from his celestial throne in Amaravati, grew deeply uneasy. He feared that should Sagara complete his hundredth sacrifice, the mortal king might displace him from his heavenly dominion. To preserve his position, Indra descended to earth cloaked in invisibility and stole the sacrificial horse while it was grazing in a remote meadow. He carried the horse down into the darkest reaches of Patala, the underworld, and tethered it near the hermitage of Sage Kapila. Kapila was no ordinary mortal; he was a manifestation of Lord Vishnu, sitting in a state of profound meditation known as 'Samadhi,' seeking to bring the light of knowledge to the world. Indra placed the horse behind the meditating sage, knowing that the hot-tempered sons of Sagara would soon come looking for it.
When news of the horse’s disappearance reached Ayodhya, King Sagara was distraught. The ritual could not be completed without the horse, and its loss was a mark of supreme disgrace. He summoned his sixty thousand sons and commanded them to scour every corner of the earth. 'Do not return,' he declared, 'until the horse is found and the thief is punished.' The sons set out with a ferocity that shook the foundations of the world. They searched the forests, the mountains, and the islands, but the horse was nowhere to be found. In their desperation and mounting rage, they began to dig into the very crust of the earth. Using their divine weapons and immense strength, they tore through the soil and rock, creating massive chasms that eventually filled with water, giving rise to the name 'Sagara' for the ocean.
Their digging led them deeper and deeper, through the layers of the terrestrial world and into the subterranean realms. As they descended, they encountered the four great elephants that support the world: Virupaksha in the east, Mahapadma in the south, Saumanasa in the west, and Bhadra in the north. Each elephant encouraged them to continue their search for the sake of dharma. Finally, the brothers reached the depths of Patala. There, in a serene clearing illuminated by a soft, unearthly glow, they saw the sacrificial horse. It was grazing peacefully near the motionless figure of Sage Kapila, whose skin was covered in the dust of ages and whose breath was so shallow it seemed he was part of the stone itself.
