Mhasoba
Mhasoba, pronounced "MUH-SO-BAA", is a horned buffalo deity of pastoral tribes in Western and Southern India. In Maharashtra, many Gawlis (tribes making their living cow-herding and by selling milk and milk products) have been worshipping this deity for hundreds of years.
Mhasoba is sometime connected with Shiva, who may have been a pre- Hindu deity adopted by Hindu culture. In the Mhasoba cult of Maharashtra, Mhasoba (Mahisha/Mahesha, which is another name for Shiva/Shankar) is worshipped with his wife Jogubai ( Durga).
