As per Hindu legendary beliefs, Sage Narada visited the celestial court of Shiva at Mount Kailash to present to him a fruit, the gnana-palam (literally, the fruit of knowledge). He decided to award it to whichever of his two sons who first encircle the world thrice. Accepting the challenge, Murugan started his journey around the globe on his mount peacock. However, Ganesha, who surmised that the world was no more than his parents Shiva and Shakti combined, circumambulated them and won the fruit. Murugan was furious and felt the need to get matured from boyhood and hence chose to remain as a hermit in Palani.
The idol of the Muruga in Palani was created and consecrated by sage Bogar, one of Hinduism’s eighteen great siddhaars, out of an amalgam of nine poisonous herbs or Navapashanam.
