Upa Puranas

The word Puranas (Sanskrit: पुराण, purāṇa) literally means "ancient, old", and it is a vast genre of Indian literature about a wide range of topics, particularly myths, legends and other traditional lore. Composed primarily in Sanskrit, but also in regional languages, several of these texts are named after major Hindu deities such as Vishnu, Shiva and Devi. The Puranas genre of literature is found in both Hinduism and Jainism.

The Puranic literature is encyclopedic, and it includes diverse topics such as cosmogony, cosmology, genealogies of gods, goddesses, kings, heroes, sages, and demigods, folk tales, pilgrimages, temples, medicine, astronomy, grammar, mineralogy, humor, love stories, as well as theology and philosophy. The content is highly inconsistent across the Puranas, and each Purana has survived in numerous manuscripts which are themselves inconsistent. The Hindu Puranas are anonymous texts and likely the work of many authors over the centuries; in contrast, most Jaina Puranas can be dated and their authors assigned.

There are 18 Maha Puranas (Great Puranas) and 18 Upa Puranas (Minor Puranas), with over 400,000 verses.

The difference between Upa Puranas and Maha Puranas has been explained by Rajendra Hazra as, "a Maha Purana is well known, and that what is less well known becomes an Upa Purana". Rocher states that the distinction between Maha Purana and Upa Purana is ahistorical, there is little corroborating evidence that either were more or less known, and that "the term Maha Purana occurs rarely in Purana literature, and is probably of late origin."

The Upa Puranas are 18 in number, with disagreement as to which canonical titles belong in that list of eighteen. They include among many: Sanat-kumara, Narasimha, Brihan-naradiya, Siva-rahasya, Durvasa, Kapila, Vamana, Bhargava, Varuna, Kalika, Samba, Nandi, Surya, Parasara, Vasishtha, Devi-Bhagavata, Ganesha, Mudgala, and Hamsa, with only a few having been critically edited. The Ganesha and Mudgala Puranas are devoted to Ganesha. The Devi-Bhagavata Purana, which extols the goddess Durga, has become (along with the Devi Mahatmya of the Markandeya Purana) a basic text for Devi worshipers.
