तिरुमंत्रम्

The Tirumantiram () or Thirumantiram is a Tamil poetic work, written either in the 2nd century BCE and 4th century CE by Tirumular. It is the tenth of the twelve volumes of the Tirumurai, the key texts of Shaiva Siddhanta and the first known Tamil work to use the term. The Tirumantiram is the earliest known exposition of the Shaiva Agamas in Tamil. It consists of over three thousand verses dealing with various aspects of spirituality, ethics and praise of Shiva. But it is more spiritual than religious and one can see the difference between Vedanta and Siddhanta from Tirumular's interpretation
