count, for which Nathamuni explained, once he finish singing these 10 pasurams 12,000 times, Nammalvar himself will come and he need not bother about the count. He kept full faith in Nammalvar and started singing the pasurams with dedication under the tamarind tree under which Nammalvar himself sat 4,000 years ago (in relation with Nathamunigal's period). Once he completed 12,000 times, Lord Aravamudhan advised Vishvaksenar (the head or the chief of the army of Lord) to go and bless the Saint Nathamuni again as Nammalvar (Nammalvar is believed to be the avatar of Vishvaksena). Thus, Nammalvar himself came in front of Nathamuni and granted him all the 4,000 pasurams of all Alvars instead of just 1,292 written by him. He came back with immense happiness and thanked Aravamudhan and Nammalvar profusely. Nathamuni, thus, revived the Naalayira Divya Prabandham, hence becoming the first acharya of the Sri Vaishnava tradition. Nathamuni is considered to be an incarnation of a Nityasuri in Vaikuntha, named Gajananar. His grand disciple is Ramanuja himself, who is considered as an incarnation of Adiseshan. The relationship between Nammalvar and Nathamuni is attested by the Guru-paramparā, Divya sūri charita, and Prappannāmŗta. The Prappannāmŗta also attests that Nathamuni was born in the village Viranarayana. Viranarayana is today generally identified as Kattumannarkoil. Nathamuni is said to have died at Gangaikonda Cholapuram. His father's name was Iśvara Bhaṭṭa and his son's name was Iśvaramuni. His grandson was Yamunacharya who was probably named in commemoration of a pilgrimage that Nathamuni took to the banks of the Yamuna along with his son (Iśvara Muni) and daughter-in-law. It is believed that his other names were Sadamarsana Kula Tilakar, Sottai Kulaththu Arasar, and Ranganatha Acharya. Life history Compilation of the Naalayira Divya Prabandham He spent time travelling in North India. He learned about Naalayira Divya Prabhandam, but he heard only ten hymns. He wanted the rest. He recited 12,000 times, Kanninun Siruthambu, a poem in praise of Nammalvar. Nammalvar appeared and gave the 4000 hymns (Naalayira Divya Prabhandam). He was the one who brought back the 4000 hymns. In addition to teaching the hymns to his two nephews at Srirangam, he introduced them into the Srirangam temple service at the Sri Ranganathaswamy Temple, Srirangam, where he was the temple administrator.The story goes that Nathamuni, while at the Vishnu temple at Kattumannar Koil his native place, heard some Brahmins from the Southern end of the Peninsula recite
