[1] Tiruvasakam and Tirukovayar by Manickavasagar are included as the eighth, nine parts are compiled as the ninth Tirumurai out of which most are unknown, and the tenth as Tirumandiram by Tirumular, the famous Siddhar.
They made a tremendous impression on the people by singing the praise of Shiva in soul-stirring devotional hymns.
During the Pallava period these three travelled extensively around Tamil Nadu offering discourses and songs characterised by an emotional devotion to Shiva.
[7] Appar (alias Tirunavukkarasar) was born in the middle of the 7th century in Tiruvamur, Tamil Nadu, and lived about 81 years.
[7] Manikkavasagar's Tiruvasakam and Tirukovayar are compiled as the eighth Tirumurai and is full of visionary experience, divine love and urgent striving for truth.
[11] Tirumandiram represents another school of thought detailing agamic traditions, which run parallel to the bhakthi movement.
Nambi's Tirutottanar Tiruvanthathi followed an exclusive style of mincing Tamil and Sanskrit verses in anthati meter similar to Tevaram of the trio.
[14] Sekkizhar compiled and wrote the Periya Puranam listing the life stories of the sixty-three Shaiva Nayanars, poets of the God Shiva who composed the liturgical poems of the Tirumurai, and was later himself canonised and the work became part of the sacred canon.
[18] It is believed that by divine intervention Nambi found the presence of scripts, in the form of cadijam leaves half eaten by white ants in a chamber inside the second precinct in Thillai Nataraja Temple, Chidambaram.
[17][18] The brahmanas (Dikshitars) in the temple informed the king about the tradition that only when all three poets come together, that the chamber can be opened, and Rajaraja found a worakaround by consecrating the images of the saint-poets through the streets of Chidambaram.
[22] The focus of the moovars' (first three poets) hymns suggests darshan (seeing and being seen by God) within the puja (worship) offering.
[25] Though these two systems are overlapping, Agamic tradition ensures the perpetuation of the Vedic religion's emphasis on the efficacy of ritual as per Davis.
[25] Odhuvars, Sthanikars, or Kattalaiyars offer musical programmes in Shiva temples of Tamil Nadu by singing Tevaram after the daily rituals.
[28] One of the first anthologies of moovars' hymns called the Tevara Arulmuraitirattu is linked to Tamil Saiva siddhantha philosophy by grouping ninety-nine verses into 10 categories.
[28] The category headings are God, soul, bond, grace, guru, methodology, enlightenment, bliss, mantra and liberation - corresponding to Umapthi's work, Tiruvarutpayan.
