Thiru Innambur is the holy spot where sages like Agasthiyar were initiated with knowledge of literature. Hence the names Ezhuthu arivitha naathar, Ezhuthari naathar, Aksharapureeswarar for the presiding deity.
Thiru Innambur is at 2 kms from Puliyancheri(enroute Kumbakonam and Swamimalai). Students who worship here would succeed in examinations and excel in their academics. Devotees have claimed that their memory powers have enhanced after worshipping here frequently!
