Sage Narada once visited the celestial court of Lord Shiva at Mount Kailash to present to Him a fruit, the gyana-pazham (literally, the fruit of knowledge), that held in it the elixir of wisdom.
Upon Lord Shiva expressing his intention of dividing the fruit between his two sons, Ganesha and Karthikeya, the Sage counselled Him against cutting it. There at, He decided to award it to which ever of his two sons first circled the world thrice. Accepting the challenge, the Lord Karthikeya started his journey around the globe on his sacred bird, the peacock.
However, Lord Ganesha, who surmised that the world was no more than his parents Shiva and Shakti,circumambulated them. Pleased with their son's discernment, Lord Shiva awarded the fruit to Lord Ganesha. When the Lord Subrahmanya returned, he was furious to learn that his efforts had been in vain. In deep dudgeon, he decided to leave Mount Kailash, and take up his abode in a place where the land and people would be unequivocally his and for him. Thus, it was that He came to what is today known as Palani, a name derived from the manner of His Parents trying to mollify him and prevail upon him to return to Kailash - Gnana Pazham Nee appa (Tamil for "You are the fruit of wisdom sire") and thus, implying that being the embodiment of wisdom, he had no need for the fruit. Thus, being the abode of wisdom, the place took on its master's name - Pazham Nee or Pazhani, anglicised as Palani.
