180 - అథ పఞ్చమీవ్రతాని.

Summary of chapter 180 of the Agni Purāṇa is as follows:

Vratas on the fifth tithi centre on the propitiation of the eight great nāgas. On the śukla-pañcamīs of Śrāvaṇa, Bhādrapada, Āśvayuja, and Kārtika, the worshipper venerates the eight serpent-lords: Vāsuki, Takṣaka, Kāliya, Maṇibhadra, Airāvata, Dhṛtarāṣṭra, Karkoṭaka, and Dhanaṃjaya. Each nāga is worshipped with his preferred flower, milk, and sandal, and receives a specific prayer. The eight nāgas collectively bestow abhaya (fearlessness), long āyus, vidyā, yaśas, and śrī upon the devout worshipper. Nāga-pañcamī thus integrates serpent veneration—an ancient substratum of Indian religion—within the Purāṇic vrata framework.
