In the morning of Day 4 of the 2016 Arunachala Karthigai Festival, the vahana for Lord Chandrasekara is the naga.
The use of the word naga usually refers only to mythological serpents while snakes living in nature are called sarpas. However the word naga is also used to represent the cobra.
The cobra which is seen coiled around the neck of Lord Shiva, represents power over destruction and creation. It primarily represents rebirth, death and mortality—due to the casting of its skin thus being symbolically "reborn". The snake also represents Kundalini Shakti and as a vahana of Lord Shiva depicts desires kept under control of the Divine.
