Having resolved to obtain the nectar of immortality, the gods and asuras joined forces to churn the cosmic ocean. For this monumental task, they chose the great mountain Mandara as their churning rod and the mighty serpent Vāsuki as their rope. With tremendous effort and energy, they wrapped Vāsuki around Mandara and began to churn the ocean. For a thousand years, they persisted in this endeavor. But as the churning continued, Vāsuki, used as the rope, suffered terribly. Poisoned by the strain, the serpent began to emit deadly venom from his many heads, biting the rocks with his fangs in agony. From this torment arose a dreadful, blazing poison, Hālāhala, as fierce as fire. Its toxic fumes scorched the entire world—gods, asuras, and humans all suffered under its burning wrath. Alarmed and desperate, the gods sought refuge with the great Lord Śaṅkara, also known as Rudra and the Lord of Beasts. They approached him, praising his glory and crying out, “Save us, save us!” Moved by their pleas, the Lord of lords appeared before them. At that moment, Hari—Viṣṇu, bearing the conch and discus—also manifested. Smiling, Hari addressed Rudra, the wielder of the trident: “What is this that has arisen while the gods were churning?” He continued, “O best of gods, this poison that has appeared belongs to you. Please, standing at the forefront, accept it, O Lord.” Having spoken thus, Hari, the best of gods, vanished from their sight. Seeing the distress of the gods and recalling Hari’s words, Hara, the Lord of gods, took up the dreadful Hālāhala poison, potent as nectar. After accepting the poison and saving the worlds, he dismissed the gods and departed. With the danger averted, the gods and asuras resumed their churning, O delight of the Raghus. But soon, the massive Mandara mountain, serving as the churning rod, began to sink into the netherworld. Distressed, the gods, joined by the Gandharvas, praised Madhusūdana, Viṣṇu: “You are the refuge of all beings, especially those who dwell in heaven. Protect us, O mighty-armed one; you must lift the mountain!” Hearing their prayer, Hṛṣīkeśa assumed the form of a giant tortoise. Lying in the ocean, Hari placed the mountain upon his broad back, supporting it from below, while with his hand he grasped the summit of Mandara. Standing among the gods, the supreme person himself churned the ocean. After another thousand years of churning, a man embodying the science of life arose from the waters, holding a staff and water-pot. This was Dhanvantari, the first physician. Alongside him, radiant apsarases—celestial maidens—emerged from the churning, born of the ocean’s essence. Sixty crores of these luminous apsarases came forth, attended by countless companions. Yet neither gods nor asuras claimed them; thus, these maidens became common to all. Next, Varuṇa’s daughter, Vāruṇī, blessed with great fortune, arose from the ocean, seeking acceptance. The sons of Diti, the asuras, rejected her, but the sons of Aditi, the gods, received her with honor. Thus, the Daityas became asuras, and the sons of Aditi became suras; the gods rejoiced greatly at the acceptance of Vāruṇī. Then appeared Uccaiḥśravā, the foremost of horses, the radiant Kaustubha gem, and, at last, the supreme nectar. For the nectar’s sake, a great and terrible conflict erupted. The sons of Aditi fought fiercely with the sons of Diti; all the asuras allied with the rākṣasas, and a battle of unimaginable ferocity broke out, shaking the three worlds. As destruction spread everywhere, mighty Viṣṇu took on an enchanting form and swiftly seized the nectar. Those who dared approach him in battle were crushed by Viṣṇu’s power. In this fierce war between the Daityas and the Ādityas, the sons of Aditi slew the sons of Diti. When her sons were slain, Diti was overcome with grief. She approached her husband, the sage Kaśyapa, son of Mārīca, and spoke with sorrow: “O revered one, I am bereft of sons, slain by your mighty children. I desire a son, gained through long austerity, who will be the slayer of Indra. Permit me, O lord, to undertake austerity and obtain such a son.” Hearing her anguished plea, Kaśyapa, radiant and compassionate, replied, “So be it. May auspiciousness be yours. Remain pure, O possessor of austerity. You will bear a son who will slay Indra in battle. If you remain pure for a full thousand years, you will bear from me a son who will destroy the three worlds.” Having spoken, the sage gently touched her with his hand, blessed her, and departed to resume his own austerities. Filled with delight, Diti traveled to the place called Kushaplava and began her severe penance. During her austerities, Indra, endowed with supreme virtues, served her diligently. He brought her fire, kusa grass, wood, water, fruits, roots, and anything else she desired. With massages and constant care, Indra attended upon Diti at all times. When only ten years remained of her thousand-year vow, Diti, greatly rejoicing, spoke to Indra, unaware of the destiny that lay before her.
