7th century ce?)
A Śrī Vidyā text, composed of 320 devotional verses; it takes the form of a dialogue between Agastya and Hayagrīva, praising the all-powerful, but benign goddess, Tripurasundarī. Traditionally ascribed to Śaṅkara, the text, like the cult associated with it, seems to have originated amongst Kaula Śaivas, before moving south and assimilating elements of brahmin Vedānta culture. Now forming the second part of the Brahmāṇḍa Purāṇa, it has become an exceptionally popular work, claimed by some to be the most widely used Śākta Tantra in India. The best-known commentary appeared in 1728, composed by Bhāskararāya Makhin.
