Brahma's central icon (murti) made of marble was deified in the garbhagriha 718 AD by Adi Shankara. The icon depicts Brahma, seated in a crossed leg position in the aspect of creation of the universe (the Vishvakarma form). The central image is called the chaumurti (four-faced idol). It is of life size with four hands and four faces, each oriented in a cardinal direction. The four arms hold the akshamala (rosary), the pustaka (book), the kurka (kusha grass) and the kamandalu (water pot). Brahma is riding on his mount, the hamsa. The four symbols held by Brahma in his arms (the rosary, Kamandalu, book and the sacrificial implement kusha grass) represent time, the causal waters from which the universe emerged, knowledge and the system of sacrifices to be adopted for sustenance of various life-forms in the universe. Gayatri's image sits along with Brahma's in centre to his left. Savatri alias Sarasvati sits to the right of Brahma, along with other deities of the Hindu pantheon. Images of the peacock, Sarasvati's mount, also decorate the temple walls. Images of the preserver-god Vishnu, life-sized dvarapalas (gate-keepers) and a gilded Garuda (eagle-man, mount of Vishnu) are also seen in the temple.
