The temple follows the traditions of the Thenkalai sect of Vaishnavite tradition and follows vaikanasa aagama. The temple priests perform the pooja (rituals) during festivals and on a daily basis. As at other Vishnu temples of Tamil Nadu, the priests belong to the Vaishnavaite community, a Brahmin sub-caste. The temple rituals are performed four times a day: Kalasanthi at 8:00 a.m., Uchikalam at 12:00 p.m., Sayarakshai at 6:00 p.m., and Ardha Jamam at 8:30 p.m. Each ritual has three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Bhakthavatchala Perumal and Kannamangai Thayar. During the last step of worship, nagaswaram (pipe instrument) and tavil (percussion instrument) are played, religious instructions in the Vedas (sacred text) and Nalayira Divya Prabandam are recited by priests, and worshippers prostrate themselves in front of the temple mast. There are weekly, monthly and fortnightly rituals performed in the temple.
During the Tamil month of Chittirai, Brahmotsavam, a 10-day festival is celebrated and the festival deity is taken in procession around the streets of the temple in different mounts each day. The other festivals associated with Vishnu temples like Krishna Jayanthi, Saturdays of Tamil month Puratassi, Navratri, Vaikunta Ekadasi and Vijayadasami are celebrated during the respective days.
