Muthappan Temple

Sree Muthappan is a Hindu deity worshipped commonly in Kannur district of north Kerala state, South India. Muthappan and Thiruvappan, are considered to be a manifestation of Shiva and Vishnu, and hence Muthappan. It is said that if you call Him with Bhakti, He hears your prayer.
Worship of Muthappan is unique, in that it does not follow the Sattvic (Brahminical) form of worship, as in other Hindu temples. The main mode of worship is not via idol worship, but via a ritual enactment of Muthappan, performed daily at the Parassinikadavu temple. Fish is used as an offering to Muthappan, and people of all castes, religions and nationalities are permitted to enter the temple and take part in the worship.
Muthappan is also the principal deity in the ritualistic Theyyam dance (Muthappan Theyyam) performed in the famous Parassinikkadavu temple. The ritual performers of Muthappan Theyyam belong to the tribal community of Kerala. It is unique because in Kerala both the upper-caste Brahmins, and the lower-caste tribals, both have a significant contribution to the major forms of worship
Sree Muthappan is believed to be the personification of two divine figures - Thiruvappana and Vellatom. The dual divine figures Thiruvappana and Vellatom are similar to those of the Theyyamkaliyattem of the Northern Malabar region.
