SHIVA PURANA

Lord Siva�s 'Ekadasa Rudra� manifestations

 As Daithyas were constantly distressing Devas, the latter approached Sage Kashyap. The Sage too felt quite upset with the evil actions prepetrated by the Demons and desired to secure a lasting solution to punish the Demons. He executed a rigorous ‘Tapasya’ to the most merciful Shankara who appeared and rewarded with a windfall that soon the tribulations by Daityas would vanish as He would bless Devi Surabhi with Eleven Expressions as Eakadasa Rudras ( Eleven Rudras) to wipe out the Daithyas engaged in the tortures by the Demons. The Ekadasa Rudras were: Kapali, Pingal, Bheem, Virupaksha, Vilohit, Shastra, Ajapaada, Ahirbudhya, Shamshu, Chand and Bhava. A whole generation of Demons was indeed wiped out by the Grace of Maha Deva.
