Entrance to the middle sanctum (jaba tengah) is marked with three white-painted paduraksa portals. The entrance to the left is used for entry, while the entrance to the right is used for exit. The central door is usually closed and is only opened during the pura's main festival e.g. the biannual piodalan festival. The central portal is where sacred objects, heirloom, and offerings could pass during festival time. All three flight of stairs which lead to the paduraksa portals is flanked with mythical figures of Naga. Sculptures inspired by the epic of Mahabharata, e.g. of Arjuna, Bima, and Yudhistira dots the landscape of the stair climb. On the uppermost level of these is the statue of Krishna, the worldly form of Vishnu.
