Matangi is the ninth of the ten Mahavidya Goddesses. Like Goddess Saraswati, She governs speech, music, knowledge and the arts. Hence Goddess Matangi is also known as Tantric Saraswati.
Although Goddess Matangi is compared with Goddess Saraswati, She is often associated with pollution and impurity. She is considered an embodiment of Ucchishta (उच्छिष्ट) which means leftover food in hands and the mouth. Hence, She is also known as Ucchishta Chandalini and Ucchishta Matangini. She is described as an outcaste and offered left-over and partially eaten food i.e. Ucchishta to seek her blessings.
There are several legends which are associated with Goddess Matangi. Once, Lord Vishnu and Goddess Lakshmi visited Lord Shiva and Goddess Parvati. A feast was arranged by Lord Shiva and Goddess Parvati in honor of visiting couple.
While eating, the deities dropped some of the food on the ground. A beautiful maiden arose from dropped food who asked for their left-overs. The four deities granted her their left-overs as Prasad.
Goddess Matangi is often represented as emerald green in complexion. Goddess Matangi is depicted with four arms in which She holds a noose, sword, goad and a club. She is portrayed in red dress and adorned with golden jewelry. She is shown sitting on a golden seat. In Raja Matangi form, She is portrayed with the Veena along with a parrot.
Goddess Matangi Sadhana is prescribed to acquire supernatural powers, especially gaining control over enemies, attracting people to oneself, acquiring mastery over the arts and gaining supreme knowledge.
