The temple priests perform the
pooja (rituals) during festivals and on a daily basis based on Vaiksana Agama. As at other Vishnu temples of Tamil Nadu, the priests belong to the
Vaishnavaite community, a Brahmin sub-caste. The temple rituals are performed six times a day:
Ushathkalam at 7 a.m.,
Kalasanthi at 8:00 a.m.,
Uchikalam at 12:00 p.m.,
Sayarakshai at 6:00 p.m.,
Irandamkalam at 7:00 p.m. and
Ardha Jamam at 10:00 p.m. Each ritual has three steps:
alangaram (decoration),
neivethanam (food offering) and
deepa aradanai (waving of lamps) for both Neelamegha Perumal and Tirukannapura Nayagi. During the last step of worship,
nagaswaram (pipe instrument) and
tavil (percussion instrument) are played, religious instructions in the
Vedas (sacred text) are recited by priests, and worshippers prostrate themselves in front of the
temple mast. There are weekly, fortnightly, and monthly rituals performed in the temple. The major festival, the twelve-day Brahmotsavam is celebrated during the
Tamil month of Vaikasi (April - May). Masi Mahotsavam is another ten-day festival during the Tamil month of Masi (February - March). During these festivals the legend of marriage of Padmasini with Sowrirarjan is enacted. As per the legend, Uparasiravasu, the ruler of fisherman community was trying to remove grains from a storehouse, when a watchman intercepted. Later during the day, the same watchman appeared as Vishnu to the ruler. He was pleased and got his daughter Padmasini married to Vishnu. The festive idol is so depicted to render a hand to his consort. During the festival,
sacred water used during the ablution of the festive deities is distributed to devotees. There are religious discourses, musical performances and floats organized during the festival. The other Vaishnavite festivals like
Krishna Janmashtami, Karthigai, Tamil New Year, Margali ten-day festival, Sankranti, Panguni Uttiram and Rohini Utsavam are celebrated. ==Food offering==
