The interior of the small sanctum (garbhagriha) holds an approximately high Shiva-lingam with four faces (mukhalinga) with elaborate hair style, three of which exude calm with meditating closed eye, smiling posture. The fourth face of Shiva is shown as energized and in action, with wide open mouth, raised nostrils and slightly bulging open eyes likely the terrible aspect in his form as Bhairava. Stella Kramrisch dates the linga inside this temple to the 8th century. The faces of the mukhalinga represent the Panchamukha aspects of Shiva iconography, where Tatpurusha, Aghora (Bhairava, Rudra), Vamadeva and Sadyojata face the four cardinal directions, while Ishana the fifth is beyond space, all directions and time as the formless absolute in Hindu theology. They symbolize the creation (Vamadeva), maintenance (Tatpurusha), destruction (Aghora), and introspective subtle reflective Sadyojata aspects of Shiva as the metaphysical Brahman.
