The Nalayira Divya Prabandham (Tamil: நாலாயிர திவ்ய பிரபந்தம்) is a collection of 4,000 Tamil verses (Naalayira in Tamil means 'four thousand') composed before 8th century AD, by the 12 Alvars, and was compiled in its present form by Nathamuni during the 9th – 10th centuries. The work is the beginning of the canonization of the 12 Vaishnava poet saints, and these hymns are still sung extensively even today. The works were lost before they were collected and organized in the form of an anthology by Nathamuni.
