A very powerful and valiant राक्षस who possessed an iron rod named सुनन्द . He had earned the boon that the rod would lose its power only on contact with women. He lived underground in a thick forest on the banks of the river निर्विन्ध्या . Once he abducted मुदावती , the beautiful daughter of विडूरथ , King of वैशाली . At last वत्सप्रि , the son of भलन्दन made मुदावती touch the iron rod of the असुर , which became powerless because of the touch of a woman, and then he ( वत्सप्रि ) killed the असुर . वत्सप्रि then married मुदावती . (Mārkaṇḍeya Purāṇa, Chapter 116) .
