Nammalvar (Tamil: நம்மாழ்வார், lit. 'Our Alvar') was one of the twelve Alvar saints of Tamil Nadu, India, who are known for their affiliation to the Vaishnava tradition of Hinduism. The verses of the Alvars are compiled as the Naalayira Divya Prabandham, where praises are sung of 108 temples that are classified as divine realms, called the Divya Desams. Nammalvar is considered to be the fifth in the line of the twelve Alvars. He is highly regarded as a great mystic of the Vaishnava tradition. He is also considered to be the foremost among the twelve Alvars, and his contributions amount to 1352 among the 4000 stanzas in the Naalayira Divya Prabandam.
According to traditional scriptures, Nammalvar was born in 3059 BCE in Alwarthirunagiri; historically he flourished in 8th century CE. In Hindu legends, Nammalvar remained speechless from the moment of his birth, sitting under a tamarind tree when he first interacted with Madhurakavi Alvar, who saw a bright light shining to the south, and followed it until he reached the tree where the boy was residing.
The works of Nammalvar were compiled by Madhurakavi as four different works, the Tiruvaymoli (1,102 verses), Tiruviruttam (100 verses), Tiruvaciriyam (or Tiru Asiriyam - 7 verses) and Periya Tiruvantati (87 verses). The works of Nammalvar contributed to the philosophical and theological ideas of Vaishnavism.
The Garudasevai festival in Nava Tirupathi, the nine Vishnu temples in Thoothukudi region, and the Araiyar Sevai during the Vaikunta Ekadasi festival in Srirangam temple are dedicated to him. The verses of Nammalvar and other Alvars are recited as a part of daily prayers and during festive occasions in several Vaishnava temples in Tamil Nadu.
The word alvar means the one who dives deep into the ocean of the countless attributes of god. The Alvars are considered the twelve supreme devotees of Vishnu who were instrumental in popularising Vaishnavism. The religious works of these saints in Tamil, songs of love and devotion, are compiled as Nalayira Divya Prabandham containing 4000 verses and the 108 temples revered in their songs are classified as Divya Desam.
