Lord Narasimha is an incarnation and one of the Dasavatharams of Lord Mahavishnu. The Lord appeared as a part Lion- part Human form in order to kill the Asura King Hiranyakashipu since this King had attained a boon which insisted that he can be killed by neither beast nor Humans. Thus, by appearing as a Lion-Man, He could kill the Asura King without violating the boon. God is omnipresent and omnipotent; God will find ways to destroy evil, God will do whatever is necessary to fulfill the just desires of a true devotee like Prahlada and God will never let down anyone who has faith in Him. This Avatar of Lord Vishnu indicates that although Hiranyakashipu is an Asura, he is blessed by the Lord since the Lord appears before him and also cradles him in His lap, consumes him and thus takes Hiranyakashipu into Himself which represents ultimate salvation. However, when Lord Nrisimha appeared, He was in an extremely angry form known as Ugra Narasimha and or Jwala Nrisimha. The angry mode continued even after the demonic element namely Hiranyakashipu was destroyed. Shri Mahalakshmi then appeared in order to calm down the Lord and so she sat on His lap and held him and thus cajoled Him to attain the Shanti (peaceful) mode. Thus, the combined form of the Lord with Sridevi sitting on His lap came to be known as Lakshmi-Nrisimha.  Worshipping Lord Nrisimha along with Mahalakshmi endows the devotee with wealth, health, prosperity, longevity and protects the devotees from disease and malefic effects of planets. In addition, it ensures the destruction of evil forces and assures the establishment of Universal peace.
