The temple priests perform the "pooja" (rituals) during festivals and on a daily basis. Like other Shiva temples of Tamil Nadu, the priests belong to the Shaivaite community, a Brahmin sub-caste. The temple rituals are performed by pandit six times a day; Ushatkalam at 5:30 a.m., Kalashanti at 8:00 a.m., Uchikalam at 10:00 a.m., Sayarakshai at 6:00 p.m., Irandamkalam at 8:00 p.m. and Arddha Jamam at 10:00 p.m. Each ritual comprises four steps: "abhishekam" (sacred bath), "alankaram" (decoration), "naivedyam" (food offering) and "deepa aradhanai" (waving of lamps) for both Arunachaleshvara and Unnamulai Amman. The worship is held amidst music with "nagaswaram" (pipe instrument) and "tavil" (percussion instrument), religious instructions in the Vedas read by priests and prostration by worshippers in front of the temple mast. There are weekly rituals like ' and ', fortnightly rituals like "pradosham" and monthly festivals like "amavasai" (new moon day), "kruttika", "purnima" (full moon day) and "chaturthi".
