"Lalitha sahasranama" is said to have been composed by eight vak devis (vaag devathas) upon the command of Lalitha. These vaag devis are Vasini, Kameshwari, Modhinee, Vimala, Aruna, Jayinee, Sarveshwari, Koulini. The sahasranama says that "One can worship Lalitha only if she wishes us to do so". The text is a dialogue between Hayagriva, an (avatar) of Mahavishnu and the sage Agastya. The temple at Thirumeyachur, near Kumbakonam is said to be where Agastya was initiated into this sahasranama. Another alternative version is the Upanishad Bramham Mutt at kanchipuram is where this initiation happened.
