The lines contained in the design of the spires is used to point upwards towards the Heavens. The compact design combined with the repetitive patterns create a sense of energy within the structure which is further strengthened by the arching spire walls. Although the northern temples are much smaller than most of the southern design, Kandarya Mahadeva appears to be much larger than it is because of its high platform and cluster of spires. The steps lead visitors into a large sanctuary containing a Shiva Lingam. The Shiva Lingam is a stone that represents the infinite nature of Shiva and is utilized for prayer and worship within the temple.
