Vairaang was one of the sons of Diti. His wife's name was Vairaangee. They had the son named Taarak (Taarak+Asur = Taarakaasur). Another Raakshas born to Diti was married to Surasaa. Their children were Shoorpadm, Sinhmukh, and Ajaamukhee. Taarak and Shoorpadm grew up together and Taarak became the emperor in Shonitpur, and Shoorpadm in Veermahendra.

Taarak was determined to conquer Devtaa but it was not an easy task so he resolved to get Var from Brahmaa Jee. He did a severe Tap and asked the Var from Brahmaa Jee that he wouldn't die. Brahmaa Jee said that "he shouldn't ask for impossible, so he might ask for another Var." Then he thought that he should ask that he should die under certain conditions, then he might be immortal.

At that time Shiv Jee was in Samaadhi, and none could disturb His Tap for His fury. So He could not marry and there was no question of His son. And even if He had the son, he will be so small that he will not be able to harm him. So he asked that he should die only by the hands of son of Shiv Jee when he is only seven days old. Brahmaa Jee said "So be it" and went away.

Now he threw all the three worlds in fright. Indra gave him His Airaavat elephant, Kuber gave him his all wealth. All good things became Taarak's property. He drove out Devtaa from Swarg and appointed Raakshas there. Devtaa could not bear all this and went to Brahmaa Jee. Brahmaa Jee came to Taarak and said - "You are very brave and courageous, but you should not harass Devtaa like this, let them live in peace in Swarg Lok."

Taarak obeyed Brahmaa Jee and came back from Swarg to Shonitpur. But his wickedness did not subside  and Devtaa continued to live in fear and troubles. Then Brahmaa Jee suggested that now there is only one way to kill him that a son should be born to Shiv Jee and he should kill him. So arrange the marriage of Shiv Jee to Paarvatee Jee who was doing Tapasyaa to get Shiv Jee as Her husband.

This job was also done, but still no son was born to Shiv Jee. With a great difficulty Kaartikeya was born on the 6th day of Maargsheersh Maas (that day is called 'Skand Shashti'). At the time of birth he had six mouths and had divine weapons of Shakti - Shool and Mahaa Astra, in his hands.

Kaartikeya was the son of Shiv Jee so he grew fast with a great valor, courage, intelligence, power and strength. Brahmaa Jee Himself performed his Jaat Karm Sanskaar (ceremonies performed at the time of birth of a child). Shiv Jee blessed him to kill the Asur and declared him as the commander of the army of Devtaa. On that day all Devtaa presented him various gifts separately. Soorya Dev gave him a chariot with a speed of thought; Yam Raaj, the Devtaa of Netherworld, gave him Dand; Agni Dev gave him Mahaa Shakti (great power); and Arun gave him Kukkut (cock) bird symbolizing the eternity of time. He rode on peacock. And he along with some other Devtaa started from Kailaash to Shonitpur to kill Taarakaasur.

Meanwhile Twashtaa, the divine architect, built a city near the silver mountain Rajatadri for Kaartikeya. Vishnu enthroned him there and declared him as the protector of the universe. Now Indra sent a messenger to Taarak that if he did not stop his atrocities he should be ready for war. Indra knew that Taarak will not agree for this so He prepared His army with Kaartikeya as its army chief and started towards Taarak's place.

Taarak thought how come that Indra was showing such a courage? He went up the palace and looked at the horizon from where a great army was coming to his palace. The war started. Indra was defeated by Taarak. Veerbhadra also kept him engaged for a long time. Then Mahaavishnu Himself tried His Chakra (divine disc), but failed against Taarak's Shakti. Then Brahmaa Jee ordered Kaartikeya to kill Taarak as only he could kill Taarak according to His Vardaan to Taarak.

So Kaartikeya forwarded to kill Taarak. Taarak insulted Devtaa to send a baby to fight with him instead of any Indra, Vishnu, Shiv etc Devtaa. Both looked up at Shakti weapon. Once Kaartikeya fell down with the hit of Taarak but soon he got up and attacked him. Then Taarak fell down, but when he got up this time the whole environment got dull. Kaartikeya greeted his parents in his mind, and threw his trident into Taarak's chest and killed him.
