Poigai Azhwar (also spelt Poygai Alvar or Poigai Alvar or Poygai Azhwar) is one of the twelve azhwar saints of South India, who are known for their affiliation to Vaishnava tradition of Hinduism. The verses of azhwars are compiled as Nalayira Divya Prabandham and the 108 temples revered are classified as Divya desam. Poigai is one of the three principal azhwars, with the other two being Bhoothathazhwar and Peyazhwar, collectively called Muthalamazhwargal who are known to be born out of divinity. Poigai composed hundred verses that are classified as Muthal Tiruvandadhi and his composition is set in the Andhadhi style in which the ending syllable is the starting one for the next verse. According to traditional account, the first three azhwars belong to Dwapara Yuga (before 4200 BC). Modern historians place the period of azhwars from the 5th to 8th centuries AD, but the chronology and relation between each other is disputed. As per Hindu legend, Poigai was found in a small pond near the Yadhotakaari temple at Tiruvekkaa. In Tamil, small pond is called poigai, and since he was found in a pond, he got the name Poigai. As per legend, the three azhwars were once were confined in a small dark enclosure during a rain in Thirukovilur and they experienced a fourth individual among them. They found out that it was god Vishnu and Poigai wished to see his face continuously but could view only from the simmering light of the lightening. With a view to maintain the continuity of light, he instantly composed hundred songs wishing light to emerge. The other two continued composing hundred songs each on Vishnu. The works of these earliest saints contributed to the philosophical and theological ideas of Vaishnavism. Along with the three Saiva nayanmars, they influenced the ruling Pallava kings of the South Indian region, resulting in changing the religious geography from Buddhism and Jainism to the two sects of Hinduism.
