When Siva said to Ganesha and Murugan, “Whoever goes around the universe first will get this mango,” Murugan immediately took off on his peacock to go around the universe, while Ganesha was thinking how to do that (He has got only a slow moving mouse). When Murugan was going around, He met Rishi Ahasthir. Murugan created Tamil language and taught Tamil to Ahasthir (so, Ahasthir was the first Tamil student). This delayed Murugan and in the mean time Ganesha circumambulated (pradakshina) Siva and Parvathi and received the Mango, and Murugan arrived just in time (teaching us that parents are the universe). The Tamil word “Murugan” means “Beautiful.” No wonder Murugan created that word to describe Him.
Lord Siva is the Supreme Being of the universe, not one of many gods. To Saivites Siva is the supreme being; to Vaishnavites Vishnu is the supreme being. The soul starts with experiencing the world. On one side the soul is pulled by veiling grace toward the world. On the inside the soul is pulled by revealing grace toward God. Resolving karma, maturing in the world, fulfilling dharma, we move toward imperturbability, realization, moksha.
