Divya Prabandham
The Nalayira Divya Prabandham is a collection of 4,000 Tamil verses (Naalayiram in Tamil means 'four thousand') composed by the 12 Alvars, and was compiled in its present form by Nathamuni during the 9th – 10th centuries. The work, an important liturgical compilation of the Tamil Alvars, marks the beginning of the canonization of 12 Vaishnava poet saints, and these hymns are still sung extensively today. The works were lost before they were collected and organized in the form of an anthology by Nathamuni.
The Divya Prabandham sings the praise of Narayana (or Vishnu) and his many forms. The Alvars sang these songs at various sacred shrines known as the Divya Desams. The Tamil Vaishnavites are also known as Ubhaya Vedanti (those that follow both Vedas, i.e., the Sanskrit Rigveda, Yajurveda, Samaveda and Atharvaveda, as well as the Tamil-language Tiruvaymoli, a work which many South Indian devotees regard as the Tamil Veda). In many temples — Srirangam, for example — the chanting of the Divya Prabhandham forms a major part of the daily service.
