The sanctum can be entered through the south gateway, one the reclining Vishnu is facing. The doorway as one enters from the mukhamandapam, also called the Gayatri mantapa, is flanked by Jaya and Vijaya dvarapalas. The sanctum chamber is round, even though the vimana above is an oval projection. The circumambulation path (pradakshina-patha) is set in a square, to journey clockwise. This garbha-griya is surrounded by a raised square Tiruvunnali, encircling pillars and another inner square. As the visitor completes the circumambulation around the resting Vishnu, one sees four additional images. On the western wall inside the core sanctum is Vighnesvara (son of Shiva and Parvati, Ganesha, Shaivism), on the northwestern corner is Yoga-Ananta (Vishnu seated in yoga asana on Sesha, Vaishnavism), on the northeastern side is Yoga-Narasimha (Narasimha seated in yoga asana, Vaishnavism), and on the eastern wall is Durga (an aspect of Parvati, Shaktism).
