Sadaiya Nayanar

The Tamil Periya Puranam, a twelfth-century hagiography by Sekkizhar and the main source about the sixty-three Nayanars, only dedicates one hymn to him, naming his son Sundarar and wife Isaignaniyar.

Sadaiya Nayanar and his wife lived in Tirunavalur, in the kingdom of Thirumunaipadi, in the present-day Indian state of Tamil Nadu.

[5] The Hindu spiritual guru Sivananda Saraswati (1887–1963) praises the non-attachment to samsara and the worldly things, which he demonstrates by giving away his child without hesitation.

[5] As Nambi Arurar grew up and attained a marriageable age, Sadaiya Nayanar started searching for a suitable wife for his son.

[5][4] Sundarar refers to his father Sadaiyan in the Tiruthonda Thogai, a hymn to Nayanar saints, which is the first compilation of the list.

The images of the Nayanars are found in many Shiva temples in Tamil Nadu.
