Religious doctrine is a feature that has been interwoven in people's lives since then. The belief that God is the primary cause of good and evil in the world gave rise to the worship of God. People of the Sangam period followed the worship of minor deities, nature worship and major worship. During the Sangam period each type of area had its own deities. In this way the people of Mullai land worshiped Mayon (Tirumal), the people of Kurinji land worshiped Seyon (Murugan), the people of Marutha land worshiped Venda (Indra), and the people of Neythal land worshiped Varuna. However, there are many evidences in the Sangam literature that 'people also worshiped shiva' during the Sangam period itself.

The majority of hymns in some of the Sanga literature works such as Etuthogai and paththupattu praises Shiva and Muruga, which are the symbols of Saivism. Thirumurugatruppadai in Pathitrupathu and Kurundogai in etuthogai praise Lord Muruga.  Apart from Parippadal and Natrinai (Tirumal) from the Etuthogai, all the other five books contain hymns praising Lord Shiva. In addition, it is mentioned that all the songs of God's greetings, except for Kalithogai were sung by the poet who sang Bharatam. However, doubts arise as he is said to have sung about Tirumal in Naritanai and the name of the person who sang it in the Kalithogai is not known. The aim of this article is to see how the norms of saivam have been presented.
