Matangi is one of the ten Mahavidyas - the others are Kali, Tara, Shodashi, Bhuvaneshwari, Bhairavi, Chinnamasta, Kamala, Dhumavati and Bagla Mukhi. The Mahavidyas represent some or other incarnation or manifestation of the Divine Mother. They are in this sense also to be regarded as Vidyas or different approaches to (tantric) knowledge.
Matangi resides in the throat chakra and is radiant like the Moon. Matangi is an adviser of Tripur Sundari and het worship leads the aspirant to Tripur Sundari. Matangi is invoked to achieve command over speech, creativity and knowledge, among others.
