 Thus far Shiva temples only had images of god forms, but after the advent of Rajaraja, the images of the Nayanar saints were also placed inside the temple.Nambi arranged the hymns of three saint-poets Sambandar, Appar and Sundarar as the first seven books, Manikkavacakar's "Tirukovayar" and "Tiruvacakam" as the eighth book, the 28 hymns of nine other saints as the ninth book, the "Tirumandiram" of Tirumular as the tenth book, and 40 hymns by 12 other poets, "Tirutotanar Tiruvanthathi"–the sacred "anthathi" of the labours of the 63 Nayanar saints–and Nabmi's own hymns as the eleventh book.The first seven books were later called as "Tevaram", and the whole Saiva canon, which came to include Sekkizhar's "Periya Puranam" (1135 CE) as the twelfth volume, is wholly known as "Tirumurai", "the holy book".
