The Nambudiri Brahmins (Malayalam: നമ്പൂതിരി nambũdiri, also transliterated Namputiri, Namboothiri) are Hindu Brahmins from the Indian state of Kerala, who are considered the most orthodox Brahmins in India. Its members regard themselves as the true repositories of the ancient Vedic religion and of the traditional Hindu code[2]. They perform rituals in temples of Kerala based on Tantra Vidhi, a complex and ancient branch of Tantric traditions found only in Kerala, and some Mahakshetras ("Great Temples") around India (which have a Nambudiri acting as the Head Priest). Namboothiris follow the conservative and ritualistic Śrauta traditions and the ancient Purva Mimamsa, unlike the majority of other Brahmins in India who follow the Vedanta.
