Tirukkadaimudi Temple of Tamil Nadu is also called "Sadaiyar Koyil". The temple is situated near the banks of River Cauvery. In this temple Lord Shiva is worshipped as "Kadaimudinathar" or "Lord Kiluvai" as he appeared under the Kiluvai Tree. The looping of the River Cauvery, in an almost westward flow is considered to be of significance here.

Structure of Tirukkadaimudi Temple
The presiding deity "Kadaimudinathar" or "Anthi Samrakshaneeswarar" is housed in a west facing shrine. There are also shrines here for Nataraja, Bhairava and the Tevaram trinity. Shiva Linga has 16 stripes known as "Shotasa Linga". Wealth is classified under 16 heads; hence it is believed that those worshipping Kadaimudinathar will achieve all the wealth.

The Ambal shrine is dedicated to "Abhiramavalli". The shrine is facing towards south with an entrance. Woman awaiting marriage use to tie a Mangalsutra to the Goddess for early wedding. When marriage proposals conclude happily, they take back the Mangalsutra, tie it on their neck, worship and again leave it with Mother. Their belief is that doing so would ensure the longevity of their Mangalsutra till the end of their life.
