Ugra, Raudra or Samhara Murti is one of the forms of Lord Shiva, in which his state of mood is ferocious. The fury of Lord Shiva is terrific and abnormal in its nature. It is believed that the ferocity of Lord Shiva is not desired by any of the Gods or Beings in the universe. It is said that Shaivites conjured up a concept in which Lord Shiva is referred as Sarabha and he destroyed Narasimha, a form of Lord Vishnu. Obviously it is understood that Shaivites believe Lord Shiva is the only Supreme power, negating the concept of Lord Vishnu and Vaishnavas.
