Lord Shiva is the principal deity. The pratishta is believed to be in two moods, Ugramoorthy (fierce) and Mangala pradayakan (auspicious). A common belief is that Lord Shiva is showering his blessings to his son Lord Ayyappa to fight against all evil spirits while throwing all anger to the evils. As in many Shiva shrines, a number of oxen are protected in the temple premises.
Three Poojas are held here every day. The morning section includes Usha pooja, noon section with Ucha pooja and the desk section concludes with Deeparadhana. Special weekly days are Sunday, Monday and Friday.
The 'Maha Shivaratri' held annually is one of the noted festivals of the temple. Besides Shivarathri, the temple celebrates its Thiruvutsavam every year in grand style. At times of Sabarimala pilgrimage, devotees from various states visits the temple for welfare and sake.
