Periyalvar (c. 9th century), also known as Vishnuchittar, was one of the twelve Alvar saints of South India who are known for their affiliation to the Vaishnava tradition of Hinduism.
The verses of Periyalvar and the other Alvars are recited as a part of daily prayers and during festive occasions in several Sri Vaishnava temples in South India.
[3] According to the Vaishnavite tradition, Vishnucitta or Periyalvar incarnated on this earth in the 47th year after the beginning of the Kali Era (3102 BCE).
Divya Suri Saritra by Garuda-Vahana Pandita (11th century CE), Guruparamparaprabavam by Pinbaragiya Perumal Jiyar, Periya tiru mudi adaivu by Anbillai Kandadiappan, Yatindra Pranava Prabavam by Pillai Lokacharya, commentaries on Divya Prabandam, Guru Parampara (lineage of Gurus) texts, temple records and inscriptions give a detailed account of the Alvars and their works.
The songs of Prabandam are regularly sung in several the Vishnu temples of South India daily and also during festivals.
[6][7] Periyalvar was born into a Brahmin family in Srivilliputhur, near Madurai and was named Vishnuchittar meaning "one who has Vishnu in his mind".
He renounced many aspects of common life of a man i.e., getting educated , getting married and have children, earning money, but instead focus on Bhakti (devotion), especially on doing simple tasks for god.
Once during random rounds around the city, the Pandyan king Vallabhadeva thought to take rest in a nearby temple.
The prize is 1,00,000 gold coins, tied to a large pillar, which will definitely fall if god is convinced about the answer whoever tells.
Bhudevi understood, and on Earth, when Vishnuchitta was offering water to the Tulasi plants, he found a baby crying.
[8] Apart from his native Srivilliputhur, he visited Thirukoshtiyur, Sri Ranganathaswamy Temple, Srirangam, Tiruvellarai and Alagar Kovil.
The devotees of the Sri Vaishnava sect of Hinduism pay respect to the Alvars in addition to their worship of Vishnu.
The verses of Alvars are recited as a part of daily prayers and during festive occasions in most Vishnu temples in South India.
[9] The Periyalvar Mangalasasanam festival (also called Aani Utsavam) is celebrated every year during the Tamil month of Aadi (July - August) in the Vadapadrasayi temple in Srivilliputhur.
After early morning special pujas, the presiding deities, Sri Rengamannar and Goddess Andal are taken in decorated palanquins to the car.
The festival marks the adoption of presiding deity, Andal, by Periyalvar after he found her near a Tulsi plant in the garden of Vadabadrasai Temple at Srivilliputhur on the eighth day of the Tamil month of Adi.
