The temple is revered in the verses of Tevaram, the 7th century Saivite canonical work by the three saint poets, namely, Appar, Sambandar and Sundarar. As the temple is revered in Tevaram, it is classified as Paadal Petra Sthalam, one of the 275 temples that find mention in the Saiva canon.
The temple is counted as one of the temples built on the northern banks of River Kaveri.The unique feature of this temple is that all the presiding deities are named Mangalam, indicating prosperity. Parvathi as Mangalambigai, Vinayagar as Mangala Vinayagar, Vimanam (Tower) as Mangala Vimanam, Theertham (Temple Tank) as Mangala Theertham all indicate prosperity.
The temple is one of a few temples in South India where Kaali Attam, a dance depiction of Hindu deity Kali is performed. During the KaaLiyaa Attam performance, an evil form depiction succumbs against the dancer performer depicting Kali.[6] The temple and the nearby Suryanar Kovil are closely associated in worship practices. Devotees have to visit Suryanar Kovil after visiting the Thirumangalakudi temple.
The temple priests perform the puja (rituals) during festivals and on a daily basis. Like other Shiva temples of Tamil Nadu, the priests belong to the Shaiva community, a Brahmin sub-caste. The temple rituals are performed six times a day; Ushathkalam at 6:30 a.m., Kalasanthi at 8:00 a.m., Uchikalam at 12:00 a.m., Sayarakshai at 5:00 p.m., and Ardha Jamam at 8:00 p.m. Each ritual comprises four steps: abhisheka (sacred bath), alangaram (decoration), naivethanam (food offering) and deepa aradanai (waving of lamps) for both Mangalapureeswarar and Mangalanayagi.
The worship is held amidst music with nagaswaram (pipe instrument) and tavil (percussion instrument), religious instructions in the Vedas (sacred texts) read by priests and prostration by worshipers in front of the temple mast.
