At Karamadai, a place near Mettupalayam there lived people by the name " Thottiyars ". One of the Thottiya had a (Karai Pasu) cow. All off a sudden, for a few days the cow did not give him milk.

Filled with anger the thottiya followed the cow and found his cow shedding milk to a Kaarai bush, the thottiya became very furious and with his knife banged the bush and a sound exploded from the bush and blood started gushing out of the bush, people knowing this rushed to the spot and found a Suyambu Lingam inside the bush, the same night the God appeared in the dream of thottiya and ordered the thottiya to glorify him with " Chandana Kaapu ", So did the thottiya and found that it was a beautiful Ranganathar Suyambu (which is said to be growing in size every year).

Located at 30 kms from Coimbatore on Ooty road.
