The list of the Nayanars was initially compiled by Sundarar (Sundararmurthi). In his poem Tiruthonda Thogai he sings, in eleven verses, the names of the Nayanar saints up to Karaikkal Ammaiyar, and refers to himself as "the servant of servants". The list did not go into the detail of the lives of the saints, which were described in detail in works such as Tevaram.
In the 10th century, king Raja Raja Chola I collected the volumes of Tevaram after hearing excerpts of the hymns in his court. His priest Nambiyandar Nambi began compiling the hymns into a series of volumes called the Tirumurai. He arranged the hymns of three saint poets Sambandar, Appar and Sundarar as the first seven books which he called the Tevaram. He compiled Manikkavasakar's Tirukovayar and Tiruvasakam as the eighth book, the 28 hymns of nine other saints as the ninth book, the Tirumandiram of Tirumular and 40 hymns by 12 other poets as the tenth book.
