Thiruvaikunda Vinnagaram (Vaikunta Nathan Perumal Temple), Thirunangur – Literary Mention
The temple is revered in Nalayira Divya Prabhandam, the 7th–9th century Vaishnava canon, by Periazhwar, Thirumalisai Alvar & Thirumangai Azhwar. The temple is classified as a Divyadesam, one of the 108 Vishnu temples that are mentioned in the book. During the 18th and 19th centuries, the temple finds mention in several works like 108 Tirupathi Anthathi by Divya Kavi Pillai Perumal Aiyangar.
Saint Tirumangai Azhwar, a great blessed soul, a William Wordsworth of Tamilnadu blending nature and spirituality, had drowned himself in the scenic beauty of this Divyadesa place Lord Vishnu had chosen and in his enticing handsomeness and the great Avatars He took to establish dharma and protect his devotees. His Mangalasasanam hymn may be regarded as a nutshell summary of the divine experience of Sage Veda Vysa of his glory in his Srimad Bhagavatham considered a lamp of wisdom-Gnana Deepam.
