Matanga kanyaka charitra (story of Matanga kanya)
In the olden days a sage named Matanga used to expand the creation by virtue of the power of his penance.
His son Matanga was a great saint and practitioner of penance. He was the friend of Himavanta. Once Himavanta started boasting saying that he was the father of Gauri devi. With that Matanga felt humiliated and started great penance for Mudrini devi(Mudrinidevi is none other than Mantrini devi who had received a ring from Lalita devi. She is also called Shyamala devi.
She was very happy with his penance and gave boon that she herself would be born as a daughter to him. A few days later Shyamala devi appeared in the dream of Siddhamati devi (consort of Matanga). Shyamala devi gave her a flower from the bunch decorating the formers ear. Very soon she had a female child who was named Laghushyama as she was born in a very short duration (Laghu = short, small). She was also called Matangi, Matanga Kanyaka. With her power she generated crores of virgins, who stay near Mantrini devi’s house and keep singing her praises all the time.
