Tripura Sundari

Triipura Sundari Though it called the Bhadrakali, the goddess has been transformed by the mantras into a very rare form called the Tripura Sundari, which includes the Kali form. Tripura Sundari is regarded as the supreme manifestation of Prakriti, the feminine power which is the vital energy of the universe. The inverted triangle Yantra, while used to signify Kali, is more commonly used for the Tripura Sundari who is regarded as the physical manifestation of the Yantra energy. http://www.indiayogi.com/content/temples/bhadrakali.aspx
