[2][3] Principal deity of the temple is Sree Muthappan, whose divinity is presented as a ritualistic theyyam enactment in two versions called Thiruvappan and Vellattam.
Vellattam is a minor version of the ritual enactment where the ornaments, decorations and parapharnelia are minimal thanks to which all actions including vaaythari (speech) is maximum and Attam (dance) will be at its peak.
Because the decorations are more and are of binding nature, the action is minimal and sluggish and the uriyaadal (replies to prayers) will be crisp, to the point and predictions will be accurate.
A version of the legend of Ponnu Muthappan is narrated here: The King of Ayyankara Vazhunnor of Eruvessi village and his wife,[7] Padikutty Amma, had no offspring.
Wearing a shield on his eyes, he left the family, and passed through various villages in Malabar, such as Kunnathurpadi, Puralimala, Padavil, Thillenkeri, Kannapuram, Parassinikadavu and Valluvankadav.
His wife prayed and offered to perform the rituals, Oottu, Tiruvappana and Amruthakalasam, to propitiate the boy in the month of Dhanu.
However, according to another version of the legend Muthappan climbed the coconut tree and emptied the toddy jar in the absence of Chantan.
[5] The ritualistic enactment of both the minimal and maxima versions of Sree Muthappan, Thiruvappana and Vellattam, is performed daily in the early morning and in the evening.
