Śiva, the great god, bestowed a powerful trident upon Śeṣa, the serpent king, instructing him, “With this, destroy the foremost of your enemies.” Śiva then taught Śeṣa and the other serpents the secrets and proper use of the trident. Armed with this divine weapon and his lord’s guidance, Śeṣa descended to Rasātala, the netherworld. There, in fierce battle, he slew his enemies—Daityas, Dānavas, and Rākṣasas—using the trident to vanquish them. Once victorious, Śeṣa retraced his steps, returning by the same path to the place where his lord, Hara, resided. At the very spot where the god emerged from Rasātala, a cave appeared mysteriously, and from its floor, the supremely holy waters of the Ganges began to flow forth. This water became the sacred Ganges, and before the god, a wide pool formed at its confluence. In this sanctified place, Śeṣa performed a sacrifice where fire always dwelled, causing the waters to become warm, marking the union with the Ganges. After offering worship to the god of gods, Śeṣa, illustrious and pleased, received from Śiva the desired netherworld and went to rule that realm. From that time onward, this sacred site has been known as Nāgatīrtha—a holy place that grants all desires and destroys disease and poverty. It bestows long life and prosperity, and through bathing and giving in this tīrtha, one attains liberation. Even those who listen to, recite, or remember its story with devotion are blessed with the same benefits. O best of sages, in this sacred place where Śeṣa is lord and Śiva grants power, there are hundreds of holy sites among the twenty-one tīrthas, each bestowing prosperity. One such tīrtha is called Mahānala, also known as Vaḍavānala, where the deity is the great fire and the river is named Vaḍavā. Let me tell you, O son, about this sacred place, which removes the faults of death and old age. Long ago, in the holy forest of Naimiṣāraṇya, the sages gathered and performed a great sacrificial session. Through their austerities, they subdued death itself, and during the sacrifice, death remained present but powerless. At that time, no one died—neither stationary nor moving beings—except for animals; mortals attained immortality. As a result, heaven became empty and the world overfilled, for death was disregarded. The gods, concerned, spoke to the demons: “Go, destroy that great sacrifice of the sages.” The demons replied, “We will do so, but what benefit will come to us? Nothing arises without a cause.” The gods promised, “Half the sacrifice shall be yours as well.” Thus, the demons hastened to the sages’ sacrificial session, intent on destruction. Aware of this, the sages turned to Death, saying, “What shall we do? The demons, destroyers of sacrifice, have come at the gods’ command.” After consulting with Death, all the residents of Naimiṣāraṇya, along with the subduer of Death, left their hermitages, taking only the sacred fire. They abandoned their vessels and belongings and quickly made their way to the Gautamī river to complete the sacrifice. There, after bathing, they approached the great lord for protection, praising him with joined palms. They invoked the creator of the universe, the ordainer of the three worlds, of universal form, beyond existence and non-existence—the lord of Soma. They sought refuge in Śaṃkara, the Lord of the gods, who by mere will destroys, protects, and creates all things; in Śaṃkara, the god of great fire, adorned with the mighty serpent. The blessed Lord spoke, “May you have satisfaction, O Mṛtyu.” The sages pleaded, “O Lord of the gods, terrible fear has arisen from the Rākṣasas; protect the sacrifice and us until the rite is complete.” The three-eyed, bull-bannered Lord acted, and with Mṛtyu as ally, the sages’ sacrifice reached completion. The immortals came for their share of offerings, but the sages, agitated along with Mṛtyu, addressed them: “Because the Rākṣasas were sent to destroy our sacrifice, let them be your enemies.” From that time, the Rākṣasas became the enemies of the gods. There, the gods and pure sages created a magical mare, anointing her as the wife of Mṛtyu. The water of her consecration became the river called Vaḍavā. The liṅga established by Mṛtyu is known as Mahānala, and from then on, that sacred place was called Vaḍavāsaṃgama. Where the god Mahānala resides, that sacred place grants both enjoyment and liberation. There are a thousand holy places on both banks, granting all desires, and remembrance of this site destroys all sin. Another sacred tīrtha is Ātmatīrtha, renowned for granting both enjoyment and liberation. Here, Śiva, the Lord of Knowledge, dwells. He is also known as Datta, the son of Atri, beloved of Hara, dear brother of Durvāsas, and master of all knowledge. Once, Datta approached his father Atri, bowing humbly, and asked, “How may I obtain knowledge of Brahman? Whom should I ask, and where should I go?” Atri, hearing his son’s question, meditated and replied, “Go to the Gautamī, my son, and there praise Maheśvara. When he is pleased, you will obtain knowledge.” Thus, the sacred stories of these tīrthas reveal the blessings bestowed by the gods, the triumphs of devotion, and the eternal power of worship in the holy places where Śiva’s grace flows.
