Upanishadic scriptures. Early life When Ramanuja and his guru Yadava Prakaasa parted ways due to their differences in interpreting the Vedic literature, Ramanuja became a devotee of the Varadaraja Perumal temple in Kanchi. During this period, Ramanuja's discourses and fame reached far and wide. Yamunacharya, the Vaishnavite acharya and the religious head of the Ranganathasamy temple at Srirangam had been closely following Ramanuja from a very young age. When it was time to pass on the legacy, the acharya decided that he would call upon Ramanuja. Accordingly, he summoned Sri Mahapurna, a disciple who was helping him out with the temple affairs and asked him to go to Kanchi and bring Ramanuja. When Mahapurna met Ramanuja and informed him of his guru's desire, Ramanuja was overjoyed and they both immediately left for Srirangam. But bad news awaited them at Srirangam and they both learned that Yamunacharya had died. Heart-broken, Ramanuja then left for Kanchi and refused to worship Sri Ranganatha for he held him responsible for taking away Yamunacharya from this world. As for Mahapurna, he began to assist Tiruvaranga Araiyar, the son of Yamunacharya in managing the temple affairs. But as time passed by, Tiruvaranga Araiyar and other senior members of the Vaishnavite order felt that there was a vacuum after Yamunacharya's demise and that they lacked a person who could interpret the Vedas and Sastras like Yamunacharya. So it was finally decided that Sri Mahapurna should once again go and invite Ramanuja to Srirangam. Meanwhile, in Kanchi, Ramanuja met with Kanchipurna, a fellow devotee, regularly and soon decided that he would become Kanchipurna's disciple. When he approached Kanchipurna about this, Kanchipurna politely refused as he did not belong to the same caste as Ramanuja and told him that he would get a more appropriate guru. After this Kanchipurna left for Tirupati to worship Lord Venkateswara and would return only after six months. When he finally came back, it was through him that Lord Varadaraja conveyed his wish to Ramanuja. Accordingly, Kanchipurna advised Ramanuja that it was the Lord's wish that he leave for Srirangam and find solace in Sri Mahapurna. Induction into Vaishnavism After it was decided that Mahapurna would go and invite Ramanuja to Srirangam, the acharya left for Kanchi with his wife. While on his way to Kanchi, Mahapurna and his wife decided to take some rest at Maduranthakam, a place that is located 40 km
