The Tevaram gathers the devotional hymns of three Tamil Shaiva poet saints, Sambandar, Appar and Sundarar, composed roughly between the seventh and ninth centuries and addressed to Shiva as experienced through pilgrimage to specific named temples across the Tamil region. Each hymn typically praises Shiva as present at a particular temple site, weaving together theology, geography and intense personal devotion, which has made the Tevaram a significant historical source for the early history and layout of Tamil Shaiva temple worship, not only a devotional text.
The three poets are counted among the sixty three Nayanars, the Tamil Shaiva devotional saints, and their combined output fills eleven of the twelve books of the Tirumurai, the compiled canon of Tamil Shaiva scripture, making them by far its most extensively represented contributors. Their hymns are composed in fixed metrical patterns intended for singing, and Tevaram recitation and singing remain an active part of temple ritual in Tamil Shaiva practice today, performed by trained temple singers called otuvars as part of ongoing worship rather than only studied as historical literature.
Modern printed editions of the Tevaram, produced from the nineteenth century onward following the rediscovery and organization of Tamil Shaiva manuscript material by scholars such as U. V. Swaminatha Iyer and others working on Tamil literary recovery, standardized a text that had previously circulated across dispersed manuscripts and localized temple traditions.
