Alwar thirunagiri is a panchayat town in Thoothukudi district in the state of Tamil Nadu. It is next to Srivaikuntam on the Tirunelveli – Tiruchendur Highway, Tamil Nadu. It’s about 31 km from Tirunelveli and 29 km from Tiruchendur, on the banks of the river Tamirabarani.
Alwar thirunagari Permual Temple is one of the Nava Tirupathi, nine Hindu temples dedicated to Lord as Adinatha swamy.. All these 9 temples are classified as Divya Desams, the 108 temples of Vishnu revered by the 12 poet saints, or Alwars. It is also referred to as Aathi Kshetram, Varaaha Kshetram, Theertha Kshetram, Thaantha Kshetram and Sesha Kshetram and Thiru Kurugur.
The place is believed to be the birthplace of the azhwar saint Nammalvar. Just as in other avatars, Lord Vishnu is believed to have incarnated as Nammalvar. The reason assigned to the incarnation is that Vishnu has incarnated in all 3 class of castes, but not in the fourth.
Deities
The Moolavar here is Aadi Naathan or Aadi Piraan. Taayaars here are Aadi Natha Valli and Kurukoor Valli. There is a shrine to Nammalwar. As an infant, Nammazhwar crawled and sat in yogasana in a hole of a tamarind tree. The tamarind tree, in which he resided (Tiruppulialwar) is the sthala vriksham here. The name Alwar tirunagari is attributed to Nammalwar’s presence.
Legend has it that Indra was absolved of his curse here. It is believed that Lakshmana incarnated as the tamarind tree here. Vishnu is believed to have been under a vow of celibacy, when Lakshmi meditated upon him to marry him and therefore Vishnu took her in the form of a garland of flowers (magizha malar maalai). There is another legend that Agasthyar had been blessed by Shiva, that there would be born a saint (Nammalwar) in this area, who would enthrone the language Tamil to a status equal to that of Sanskrit.
Temple
This temple covers an area of 5 acres and has three prakarams and a 5 tiered rajagopuram. The Tirumanjana Mandapam, the tirumamani mandapam and the Kannadi Mandapam are of great beauty. There are shrines to Rama, Venugopala, Narasimhar, Varaha here.
This temple is regarded as the Budhastalam (mercury) and being the ninth Divyadesam in the Tirunelveli area, it is regarded as Parama padam itself.
Alwar Tirunagari is also known for Araiyar Sevai, where the Divya Prabanda Pasurams (verses) are recited with expression, music and rhythm as in Srirangam and Srivilliputtur. This temple boasts of a nadaswaram made of stone.
Festivals
The asterism of each Alwar is celebrated here, as in Srirangam. Garuda Sevai in the tamil month of Vaikasi (Vishaka asterism – the birthday of Nammalwar) witnesses the grand Garuda Sevai, where festival images from all of the nine Nava Tirupatis congregate here. Nammalwar is mounted on the Hamsavahanam. The Paasurams on each of these deities are recited then, during this grand festival. This is the most important of the festivals in this area, and it draws thousands of visitors.
