The Puranas are ancient Hindu texts eulogizing various deities, primarily the divine Trimurti God in Hinduism through divine stories. Puranas may also be described as a genre of important Hindu religious texts alongside some Jain and Buddhist religious texts, notably consisting of narratives of the history of the universe from creation to destruction, genealogies of kings, heroes, sages, and demigods, and descriptions of Hindu cosmology, philosophy, and geography. The Puranas are frequently classified according to the Trimurti (Trinity or the three aspects of the divine). The Padma Purana classifies them in accordance with the three gunas or qualities as Sattva (Truth and Purity), Rajas (Dimness and Passion) and Tamas (Darkness and Ignorance).Puranas usually give prominence to a particular deity, employing an abundance of religious and philosophical concepts. They are usually written in the form of stories related by one person to another. The Puranas are available in vernacular translations and are disseminated by Brahmin scholars, who read from them and tell their stories, usually in Katha sessions (in which a traveling Brahmin settles for a few weeks in a temple and narrates parts of a Purana, usually with a Bhakti perspective).
