You will always notice an idol of a bull sitting on a raised platform facing the deity just outside the temple of lord Shiva. He is called Nandi and is considered to be one of Shiva’s chief attendants and also serves as a mount of the god. There are temples dedicated solely to Nandi across india. There are a lot of legends and stories related to Nandi.
I made these pictures in one such Shiva temple that I visited near my city.
