The garbhagriha (sanctum) is 15 ft high and 10 ft wide. It has the Jaya-Vijaya - the gatekeepers of Vishnu's abode - brass sculptures flanking the central icon of Siddhivinayaka. It has a dome-shaped stone ceiling. Like all Ashtavinayaka shrines, the central Ganesha image is believed to be svayambhu (self-existent), naturally occurring in the form of an elephant-faced stone. The central icon of Siddhi-Vinayaka is seated cross-legged with his consort Siddhi seated nearby, though often she is hidden with flower garlands and the sindoor paste that covers the image. The icon is sheathed in brass and with its trunk turned to the right. The sanctum also has a Shiva-panchayatana (Shiva surrounded by Ganesha, Vishnu, the Goddess and the Sun-god Surya) and a shrine to goddess Shivai.
