The main idol, at 5.5 feet high, was carved using ancient idol-making techniques called Katu Sarkara Yogam as laid down in the classical texts or Shilpa Shastras. This involves using several types of wood, clay, Ayurvedic herbs, milk, ghee, jaggery, turmeric, sandalwood, camphor, gold, silver, sand and natural glue. The annual festival at the temple falls on the day of the star sign Thiruvathira in Kumbham (February–March) as per the lunisolar Hindu calendar. The aarattu falls on the eleventh day, the last day of the festival, when the deity is taken out in a grand procession for a ritualistic bathing ceremony.
