Explanations:The Alvars were a group of 12 Vaishnava saints who lived in Tamil Nadu between the 7th and 9th centuries CE. They were known for their devotional poetry and their intense devotion to Lord Vishnu. The Alvars' influence on Vaishnavism in South India was profound, and their works are still revered today.
Ramanuja, born in Tamil Nadu, was a significant philosopher and theologian who lived in the 11th and 12th centuries CE. He is known for his contributions to the development of Vaishnavism and for his philosophical system known as Vishishtadvaita. Ramanuja's teachings were deeply influenced by the Alvars, particularly their devotional approach to worship and their emphasis on the importance of bhakti (devotion) as a means to attain moksha (liberation).
Ramanuja's philosophy was a synthesis of the teachings of the Alvars and the Upanishads. He emphasized the importance of devotion to Lord Vishnu and the role of a guru in guiding the devotee. Ramanuja's influence on Vaishnavism in Tamil Nadu and beyond was significant, and his teachings continue to be studied and practiced today.
The other options, Poigai Alvar, Bhoothath Alvar, and Pey Alvar, are all part of the 12 Alvars themselves. They are not figures who were influenced by the Alvars but are instead considered the original sources of Vaishnava devotional poetry and theology. Therefore, they do not fit the criteria of being influenced by the Alvars and being born in Tamil Nadu.
In summary, Ramanuja is the correct answer because he was born in Tamil Nadu and was deeply influenced by the Alvars, whose devotional poetry and theology significantly shaped his own philosophical and religious teachings.
