At the heart of Tamil Saiva Siddhanta lies a tapestry of sacred hymns and ritual manuals that marry fervent devotion with precise spiritual discipline. By and large, two streams feed this tradition:

1. The Tirumurai “Library”
   • Tevaram (Volumes I–III): The ecstatic hymns of Appar, Sambandar and Sundarar, still echoing through Chennai’s ancient temples each Margazhi.
   • Tiruvacakam and Tirukkovaiyar (Volume IV): Manickavasagar’s emerald-toned verses on Siva’s grace.
   • Tirumantiram (Volume VI): Thirumular’s yogic aphorisms—akin to a Tamil Patanjali—bridging devotion and nondual insight.
   • Periya Puranam (Volume XII): Sekkizhar’s epic account of the 63 Nayanmar saints, spotlighting lives lived “all for Siva.”
   Collectively known as the Twelve Tirumurai, these volumes were recently honored in a UNESCO-backed project digitizing palm-leaf manuscripts—a nod to their timeless cultural value.

2. The Shaiva Agamas
   • Twenty-eight Agamas, with Kamika, Karana and Mrgendra standing out for detailed temple-worship and tantra-inspired rites. These Sanskrit-Tamil hybrids outline everything from tantric physiology to temple architecture, keeping ritual purity razor-sharp.
   • Agama traditions saw fresh interest during last year’s International Yoga Day, when a Chennai seminar highlighted their subtle chakric maps—proof that ancient manuals can still spark modern conversations about body, breath and mind.

Meykandar’s School adds another vital layer:
• Siva Jnana Bodham and Siddhanta Muktavali—dense jewels of logical proof and philosophical finesse. These works forged a systematic Saiva Siddhanta philosophy in medieval Tamilakam, giving structure to ecstatic outpourings found in the Tirumurai.

Taken together, the Tirumurai hymns, the Agamas’ ritual playbook and Meykandar’s crisp doctrinal treatises form the backbone of Tamil Saiva Siddhanta. They continue to inspire everything from temple festivals to digital archives, keeping the flame of devotion and liberation burning bright across centuries.
