Mhalsa Narayani - Female Avatar of Vishnu

Mhāḷasā, also spelled as Mhalasa or Mahalasa is a Hindu goddess. She is venerated in two distinct traditions. As an independent goddess, she is considered as a form of Mohini, the female avatar of the god Vishnu and is called Mhalsa Narayani. Mhalsa is also worshipped as the consort of the folk god Khandoba, a form of the god Shiva. In this tradition, she is associated with Parvati, Shiva's wife as well as Mohini.

In the Mahalasa Narayani form, Mahalasa has four hands, carrying a Trishula, a sword, a severed head, and a drinking bowl. She also wears the yajnopavita (sacred thread), which is generally dedicated on male deities. She stands on a prostrate man or demon, as a tiger or lion licks blood dripping from the severed head.
