Some of the most notable temples are:
Adi Shankara, the originator of Advaita Vedanta, was born inKalady and was likely aNambuthiri. ManyHindu saints andswamis from many castes have lived in Kerala.Sree Narayana Guru, Enadinatha, Ilakkulaccanrar, Tiruppana were all outside the Brahminical caste fold;Cheraman Nayanar was a Kothayar; andChattampi Swamikal, Swami Sathyananda Saraswathi andSwami Chinmayananda, theNair caste. TheParayas of Kerala claim descent fromVasishtha.[6] There is a shrine in Kollengode in memory of a lower-caste saint, Paakkanar.[7] The theatrical dance of Rapayan Tullal is narrated by a descendant of Pakkanar.[8] ThePeriya Puranam, possibly written by a Paraya, describes the Parayas.[9]

Swami Sathyananda Saraswathi is popularly regarded as the father of contemporary Hindu renaissance in Kerala for the victorious movements he led for temple rights and the establishment ofHindu Aikya Vedi for integrating people of all castes into one religion. He is reckoned as the greatest karmayogi to upholdSanatana Dharma sinceSwami Vivekananda internationally. Sree Narayana Jayanti (Narayana Guru's birthday) and Sree Narayana Samadhi Day (the occasion of hissamadhi) are public holidays in Kerala.
Mata Amritanandamayi, known among her devotees asAmma, was selected to represent theHindu Dharma in the World Parliament of Religions in September 1991.[10]Bhagawan Nityananda was another important Hindu saint widely recognized.
Several Hindu movements important to thedevelopment of Hinduism took place in Kerala.[11] TheKarppillikkavu Sree Mahadeva Temple, (one of the most ancient in India) dedicated to the KirataAvatar ofLord Shiva still exists in Kerala.
According to Sudha Nambudiri, Thanthra Vidyapeedam, a low profileVedic andtantric pathshala (ritual school) inAluva founded by Kalpuzha Divakaran Namboodiripad and P. Madhavji in 1972 taught students in Kerala's temple shastra, Kerala's form of temple rituals, which followsAdi Shankara traditions in theGurukulam system.[12] Namboodiripad says Vidyapeedam only admits tententh standard passed boys with prior academic knowledge of theSanskrit language, selected on the basis of their individualhoroscopes every year. The seven year curriculum includes theoretical and practical studies in temple rituals based on Tantra Samuchayam, authored by Chennas Narayanan Nampoothiri, theVedas, theSanskrit language,Vaastu Shastra,Jyothisha,Yoga and meditation.[12] When completed, students are awarded a postgraduate level degree known asThanthraratna in Sanskrit byUjjain'sMaharishi Sandipani Rashtriya Ved Vidya Pratishthan and promotes students to temple priests or Sanskrit language teachers.[12] Aarsha Vidya Samajam founded by Aacharya Sri K R Manoj Ji at 1999 is an educational institution for preaching of Pancha Kartavyas; five duties: Adhyayana (Study), Anushthana (Practice), Pracharana (Promotion), Adhyapana (Teaching) and Samrakshana (Protection) of Sanathana Dharma. This institution was born with the Anugraha and Ashirwada of great Gurus for achieving the motto of Krinwantho Vishwamaryam; to make the whole world noble, through right education of Sanathana Dharma, which was not merely a divine call, but also a vision of the Aarsha Guru Paramparas, prayer of the Sadhaks, dream of our ancestors, and the birth purpose of our nation itself.
