Thanks PUrvi... Know what I read was as u sai dbut last part was diff.Vishnuji was not killing her as a women but Indra Dev forced him to kill her as only then they cl dkill rest demons who were there inside...so vishnuji killed her with chakra , then later Bhrigu rishi cursed Lord that u killed a women sonow u will always take birth from a women as a child ... as acc to him kid before birth suffer most horrible life of 9 months ....
