Yes, this is true. The temple is at a height of about 3000 feet so the climate is normally cold and also every morning at 4; 30 am Abhishekam is done in which the idol is bathed with water, milk as well as other dravayam. After the bath sweat appears in form of fine water particles on the body of the idol . Sweat is wiped with silken cloth. On every thursday, when ornaments are removed before sacred bath it is noticed that they are warm.
