In other parts of India, the Tantric name 'Kali' or 'Mahakali' is generally more popular as the consort of Shiva in his form of Rudra or Mahakala, and Bhadrakali is identified as Durga's daughter who helped her during the battle with Raktabija. Other sources state that she is the sister of Virabhadra, who was himself born of the wrath of Shiva as Rudra, and that she is the consort of a form of Mahakala or Bhairava. The deeply Tantric-influenced traditions mostly consider 'Kali' as the consort of Shiva.
