Varaha Purana

It belongs to the Vaishnavism literature corpus praising Narayana(Vishnu),but includes chapters dedicated to praising and centered on Shiva and Shakti (goddesses it calls Brahmi, Vaishnavi and Raudri).The text has been estimated to have been first completed between 10th to 12th-century, and continuously revised thereafter.The Varaha Purana includes mythology, particularly of the Varaha incarnation of Vishnu rescuing the earth at the time of a great flood. The text also includes mythology of goddesses and Shiva, and a discussion of Karma and Dharma called Dharma Samhita. A large portion of the text is dedicated to medieval geographic Mahatmya (glories) to temples and sites in Mathura and Nepal, but it curiously lacks adoring Krishna in Mathura.
