Chandikeshwara

Chandikeshwara is a great devotee of Lord Shiva. It is believed that Chandikeshwara forever lives in a state of deep meditation. It is believed that He is the one who keeps records of who visits the temple and also takes care of the properties of Lord Shiva. 

He is also considered as one of the symbols of Lord Shiva like Nandhi, Vibhuti, Rudraksha and Vilva/Belpatra leaves.

While praying to Chandikeshwara, devotees clap or rub their hands. This is to show Chandikeshwara that their hands are empty and they are not taking anything from the temple as He is considered to be the care taker and guardian of the temple belongings.
