Srivishnu form Narasimha when Narasimha killed Hiranyakashipu, and saved Prahlad , by the victory over Hiranyakashipu, Srivishnu become very happy , Happiness turns to ego start destroying Universe to enjoy his victory , there are some text states that Srivishnu unable to control himself due to half lion and half human form.
All devas including goddess Lakshmi are shocked something wrong happened to Srivishnu, all devas including Lord Brahma rushed towards the Lord Shiva for help.
All devas = o greatest lord , We are in great trouble, Srivishnu unable to control himself and started destroying the universe.
Lord Shiva = surprised, don't come here for Silly problems , I will send Veerbhadra to cool him or shant him now you people be unafraid as you came in my abode".And he summoned most terrible God of all universe who has beheaded Yagyapurush and won Vishnu at Daksha Yagya, so he already has plenty experience dealing with Lord Vishnu,His size was humongous greater than Narsimha he started playing with planets stars devas and ShreeBramha like they are balls all trilok seemed like tiny dots in front of him and his Tejas was of trillions of suns.Shree Mahabhairva Veerbhadra prostrated to Shiva and asked him humbly "Oh my lord tell me why you summoned this humble servant of yours shall I reduce triloka or whole universe in ashes or drink Akash Gangas and oceans in a nimish"(1000th of second).Shiva smiled at him and said "Oh Veerbhadra go and pacify Vishnu and if he does,nt listen to you than relieve him and bring his singhcharma to me.
Veerbhadra ran towards the place where Narsimha was threatening the Universe He said to Narsimha as a Father would suggest his beloved haywire son,"Oh Madhav you take Avatars for the benefit of world as you saved Dharma by taking Kurma Tortoise form,Varaha form and you will be Rama and Krishna in future as well ,earlier Bramha has instructed you in maintaining the creation and your kindness humility and power are world famous so why are you trying to destroy this world ,lord, demon is dead already so please withdraw this terrible form of yours and calm down as Vishnu you are, as we both are servants of Mahadeva you should listen to me as advice of mine is surely of your Hita (benefit),thus said Veerbhadra in calm but thunderous and deep voice ,but this infuriated Narsimha, He said to Shree Veerbhadra with arrogance" go to the place where you came from and don,t preach me I dont want to listen any hita vachan (kind words) Who is powerful than me i cant be destroyed or Killed so i give you a chance to leave.
Ego of Narsimha
I am the most powerful among Devas i am who is Svatantra (absolutely free),no one can be compared to my strength ,and today if i want to eat this universe let me see who can stop me ,listen my warning as you are Shiva Gana,i am letting you go Now Veerbhadra laughed and scolded him in louder and thunderous voice "Oh disillusioned Vishnu you are just a mortal your all powers are given by Shiva ,AND CERTAINLY YOU ARE NOT SVATNATRA (Free) OR BEYOND KALA,otherwise tell me what happened when son of Shiva Shree Kartik plucked out your tooth in Varahvatar you screamed in pain but cant avenge ,what happened to your Kurma when it was destroyed by Kala and now Shiva wears it in his Garland have you forgot how a humble devotee of Shiva Bramharishi Dadheechi has defeated you and your sycophant lickspittle devas single handedly scratching his head,he even humbled you by showing Greater Vishwaroop, what Shiva, only his servants have punished and defeated you many times .
The Final Warning
Do not you remember how Shivas Trishul killed your form of Vishwaksen where was your godliness than? and you are Swatntra free independent never. you are bounded like normal people ,all your Avatars are killed and have limited powers ,otherwise tell me all Gyanis Rishis are afraid of Janma Garbhawas (getting in womb) but Mahamaya sends you to take human form. you stay in stinking womb and behave like normal but powerful humans even in your Avatars.Its really laughable as you with such power which is given to you by Shiva are threatening me. And have you forgot me who has killed Yagyapurushas head who is your form according to vedas, and how I defeated and wounded you, even your head came off when i destroyed your Sharang bow, Now listen to me i warn you last time behave yourself and withdraw this Maya of yours this Maya wont affect Shivas devotees ever or see my Greater Mahamaya I tell you the truth I will kill you and take out your skin other wise calm down
Lord Sharbheshwar Arrives.
The lord Narsimha who was won by Ego and anger, tried to plunge at him with a roar, but suddenly a deafening sound trembled the universe the immense heave of the sound frightened Narsimha, his roar seemed like kids cry in front of thunder of clouds, it belittled Narsimhas prowess and Shree Veerbhadra turned into Shree Maha Sharabheshwar, the most terrible form of any God ever,his aura was not like trillions suns or moons it was much superior Shambhav tejas the terrible aura of Narsimha seemed like jugnu firefly in front of trillions suns tejas of Shree Sharabha his upper portion was of a bird with protruding and strong vajra beak his three eyes were surya chandra and agni (sun,moon and fire) his tongue was swirling in anger Shree Kali and Durga are his two terrible wings his heart is Bhairava and stomach is celestial dangerous fire, death and disease are his two thighs.The force of wings was bringing storms which flew planets Pranam to such Sharbheshwar destroyer of all enemies.
The Pacifier of Narsimha
Narsimha seemed too little in front of his Terrible form.His power prowess and tejas all secluded him now Narsimha got stunned out of fear of Lord But Shree Sharbheshwar out of extreme anger held his shoulders tied him with his tail ,punched his chest and clawed his torso and legs and flew up in the sky and than as an eagle Throws a snake he threw him on ground from sky and did it many times,Now Narsimhas ego power etc took a back seat, he requested Sharabha Dev to forgive him,and started praising him with Sharabhashtottarshatnam stotram, Narsimha said I prostrate to Shiva ,Sharva ,Vishnu Bramha roop ,the Greatest Lord of trinity etc.and said "O Lord whenever my mind becomes polluted by ego and ignorance kindly destroy my ego always",Forgive me and he became happy thus Shree Sharabha said ,"Oh vishnu in reality you are powerless now you are defeated at the end of your life" saying thus he severed his Bramharandhra and snatched his skin of Tiger.
Eulogy of Devas to Veerbhadra
And than Shree Sharabheshwar withdrew his appaling form,and all universe seemed sublime again pleasant air filled the atmosphere,Devas offered celestial flowers and sung his stotra,"Oh the Philanthropic form of Shiva you are the ultimate Guardian our Saviour but terrible than death and slayer of evil ,protector of dharma and the ones who come in your refuge.Oh Sanatana Shiva you were before the beginning and you will be there even after Mahapralaya ,oh God of Trinity and Devas there is nobody above you, you are Poorn Swatantra and the only God who is known in Vedas as "Eko hi Rudro".you destine the Leelas of Devas and everything is your Leela only".Thus spake shree Veerbhadra Oh Devas the people who want my devotion shall worship Narsimha too,it pleases me,I offer Namaskar to Narsimha" and he flew away to Kailasa and presented the skin of Shree Narsimha which turned white, to MahaShiva since than Shiva is known as Vyaghrambar Dhari, the one who wears Tiger skin ,The Clad in Tiger skin.
