Karpaka Vinayakar or Desi Vinayaka Pillaiyar is the presiding deity here, and he is portrayed with two arms and a trunk curled towards his right in the valampuri mode. This 6 feet tall mammoth image of Ganesha is a bas relief in an excavated cave, off of a hill in the precincts of the temple. Scholars says that Lord Vinayaga is the Lord of wisdom, which is confirmed by the head of elephant in the shape of sacred mantram "OM". When we draw a line from the broken left tusk, starting upward, then turning left to wards right ear and after passing through the bended left tusk up to the tip of trunk, Tamil alphabet "O" appears. The Lingam in the hand indicates the alphabet "M". Together they form "OM". This is confirmed by the lord here "Valamburi Pillayar". As Vinayagar satisfies the wishes of his devotees like Karpagam tree, he is also known "Karpaga Vinayagar".
Here Lord Vinayaga appears with 2 hands unlike in other places where he is seen with 4 hands. Also he is seen seated without Angusapasam, with his legs folded and stomach not touching the Asanam in the form of "Artha Padma" Asanam.
