The Nalayira Divya Prabandham is a monumental text that captures the devotion of the Alvars to Lord Vishnu. The hymns are composed in Tamil and cover a wide range of subjects, from the praise of Vishnu's avatars to the philosophical and devotional teachings of the Alvars. These hymns form the foundation of the Srivaishnavism tradition, which emphasizes the worship of Vishnu as the supreme deity. The work was compiled and preserved by the famous theologian and philosopher, Nathamuni. It remains a key text for understanding the development of devotional poetry in Tamil Nadu.
