The temple priests perform the puja (rituals) during festivals and on a daily basis. The temple rituals are performed four times a day; Kalasanthi at 8:00 a.m., Uchikalam at 11:30 a.m., Sayarakshai at 6:30 p.m and Arthajamam 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 Ezhutharinathar and Nithya Kalyani.
There are weekly rituals like somavaram (Monday) and sukravaram (Friday), fortnightly rituals like pradosham, and monthly festivals like amavasai (new moon day), kiruthigai, pournami (full moon day) and sathurthi. Margazhi Tiruvathirai during the Tamil month of Margazhi (December - January), Kodabisheakam during Chittirai (April - May) and Aipassi Annabishekam during Aippassi (October - November) are the three festivals celebrated in the temple.

Temple vimana
It is one of the shrines of the 275 Paadal Petra Sthalams - Shiva Sthalams glorified in the early medieval Tevaram poems by Tamil Saivite Nayanars Tirugnanasambandar and Tirunavukkarasar. Tirugnanasambandar describes the feature of the deity as:
எழில்திக ழும்பொழி லின்னம்பர் மேவிய
நிழல்திகழ் மேனியி னீரே
நிழல்திகழ் மேனியீ னீருமை நினைபவர்
குழறிய கொடுவினை யிலரே.
Tirunavukkarasar describes the feature of the deity as:
மறியொரு கையர் போலும் மாதுமை யுடையர் போலும்
பறிதலைப் பிறவி நீக்கிப் பணிகொள வல்லர் போலும்
செறிவுடை யங்க மாலை சேர்திரு வுருவர் போலும்
எறிபுனற் சடையர் போலும் இன்னம்ப ரீச னாரே.
