Thirumurai (Tamil: திருமுறை, meaning holy division) is a twelve-volume compendium of songs or hymns in praise of Shiva in the Tamil language from the 6th to the 11th century CE by various poets in Tamil Nadu. Nambiyandar Nambi compiled the first seven volumes by Appar, Sampandhar and Sundarar as Tevaram during the 12th century. During the course of time, a strong necessity was felt by scholars to compile Saiva literature to accommodate other works. 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. The eleventh is compiled by Karaikal Ammaiyar, Cheraman Perumal and others. The contemporary Chola king was impressed by the work of Nambi and included Nambi's work in the eleventh Tirumurai. Sekkizhar's Periya Puranam, composed a century later, contains the life depiction of all the 63 Nayanmars. The response for the work was so tremendous among Saiva scholars and Kulothunga Chola II that it was included as the 12th Tirumurai. Tirumurai along with Vedas and Saiva agamas form the basis of Saiva Siddantha philosophy in South India and Sri Lanka.

Tirumurai in anthology supersedes Sangam literature, which is predominantly secular in nature. The entire Tirumurai is in viruttam meter or lines of four. The principal characteristics of the head-rhyming is influenced both by syllabic and moric prosody. Poets Hymns The Shaiva Tirumurais are twelve in number. The first seven Tirumurais are the hymns of the three great Shaivite saints, Sambandar, Appar and Sundarar. These hymns were the best musical compositions of their age. The first three Tirumurais (meaning parts) of Tevaram are composed by Sambanthar, the next three by Appar and the seventh one is composed by Sundarar. Appar and Sambanthar lived around the 7th century, while Sundarar lived in the 8th century. During the Pallava period these three travelled extensively around Tamil Nadu offering discourses and songs characterised by an emotional devotion to Shiva. Their hymns include allegations against Jain monks and criticism of Jainism. Sambanthar was a
