Murugar is the second son of Siva and Parvati, brother of Lord Ganesha. Murugar is worshipped widely in Southern India.
He was once upset that Lord Siva gave the sacred fruit to Ganesha and tricked him out of winning it. He is said to have left the Himalayas, the abode of Lord Siva & Parvati and settled down on a hill top in Tamilnadu in the South. Most of the Murugar temples are located on top of small hills and he is also known as the Kundra Kadavul (Lord who is seated on a hill, kundru - hill).
Murugan is symbolized by the weapon spear (Vel in Tamil) and his
vehicle the Peacock. Murugan is also called as Arumugam, which means 'six faces' in Tamil.
It is beleived that anyone who worships God Murugan will have their prayers answered instantly.
Lord Muruga is considered very handsome, brave, just. Even though he was seen as a playful youngster, he was also extremely knowledgeable – enough to test Lord Brahma himself. When reprimanded by Lord Siva, he justified his action by telling Siva the meaning of the OM (pranava mantram). He is therefore known as Swaminathan, one who preached even to Siva.
His other namas (names) are Subrahmanya, Shanmukha, Kaartikeya, Skanda, Kumara, Devasenapati, Saravanabhava, Guha, Swaminathan, etc.
Lord Muruga has two consorts - Valli and Devasena. Valli is a tribal girl and Devasena is the daughter of Indra, the king of the Devas.
