Thir Anbil only gets a passing mention from Thirumazhisai Azhvaar but
he talks about the Sleeping Lord here alongside Kumbakonam Saarangapani and
Srirangam Ranganatha.

Naagathu Anaik Kudanthai, Vekka, Thiru Evvul
Naagathu Anai Arangam, Per, Anbil
Naagathu Paarkadal Kidakum
Aathi Nedumaal Anaipaar Karuthan Aavaan (2417)

The Lord who reclines in Kudanthai, Vekka, ThiruEvvalur, Srirangam, Koviladi and Anbil and who resides in the Ocean of Milk easily enters the hearts of his true devotees
