The idol of Lord Tulsishyam is said to be 3000 years old. It is made up of black stone. There is a hot sulphur sprint near the temple that is believed to have curative powers. A few studies with regard to similar stretches across the world have triggered wild speculation about the cause, with some suggesting it could be due to the gravitational pull from dark matter that exists on a parallel universe! Others talk of optical illusion or magnetic and gravitational anomalies.
