Thus the legendary story associated with Sri Tirukkacchi Nambi Temple of Kanchipuram is considered of considerable importance.
The legendary story in this connection has several other segments. A thorough consideration of those segments would lead to reveal the entire history behind the construction of the temple.
As the legendary evidences depicts, Tirukkacchi Nambi was the teacher of Ramanuja. The story states that when Ramanuja requested Tirukkacchi Nambi to accept him as his disciple, the latter rejected the request and told Ramanuja that he was not well-versed in the Shastras and had no formal education, but Ramanuja insisted on becoming his student on account of his great devotion to Vishnu. It was at Nambi's request that Ramanuja brought a jar full of water everyday from a well about two miles away from Kanchi for worship at the Varadarajasvami temple.
According to Vaishnava lore, Varadarajasvami chose Tirukkacchi Nambi as his medium to convey to Ramanuja, the six famous tenets of Visishtadvaita which served as the guideline for Ramanuja's teachings.
