Of all the Shaiva sects I've looked into, Saiva Siddhanta appeals to me the most. But I think they put emphasis on the Agamas in addition to the devotional Tamil works, although I could be wrong about that. I'm also not sure how much they value the Puranas.
There are dualists,monists and bhaktas.
Vinayakaji has already explained his tradition's approach.
I'm monistic Saiva Siddhanta, and you are correct. Not much emphasis on Puranas, but really not all that much emphasis on scripture period. Its more of a living tradition, where the living Guru's words are the individualized scripture, so to speak.
In dualistic tradition I observed that Puranas may play certain roles but it is not what you are looking for,its not Purana centric as such.Many Puranas were translated from Sanskrit to Tamil long back,these are popular.At the nucleus is Siddhanta because it is derived from the Siddhanta Agamas.The Agamas are extensive,independent,on par with Vedas and are higher than others.(I heard that some venerable Acharyas of dualistic sampradaya considered the Agamas as self-sufficient in all respects and did not refer to any other scriptures.The monists it appears are relatively less exclusive than some dualists on this issue as they seem to give same priority to scriptures such as Veda-Upanishads)
True,point to be noted.But the common devotee not attached to a Guru lineage is mostly just a bhaktar with no scripture at all, just as the Nayanars were.
The Tirumurai is treated with much reverence by all.The Nayanars are held in high esteem by other traditions.(Virashaivas and Smartas)
[The hymns though are essentially devotional (and philosophical),they are also used in temples for ritualistic purposes and some are laden with potency due to which they are utilized for special applications(such as attaining various things,thwarting malefic effects etc.)].
The other thing I should mention is that temples often fit everyone, so the individual can be of whatever sect or mindset. and still do his thing. This is especially true of the non-congregational South style temples. At the one I attend we get a smattering of people from all over India and elsewhere. They come for the sannidhya (feeling of God's presence) not the philosophy. So if you can find a temple like that to go to, you can THINK about it any way you personally wish.
