Thiruvasagam (Tamil: திருவாசகம் lit. "sacred utterance") is a volume of Tamil hymns composed by the ninth century Shaivite bhakti poet Manikkavacakar. It contains 51 compositions and constitutes the eighth volume of the Tirumurai, the sacred anthology of Tamil Shaiva Siddhanta.
The main message of the hymns is that the body is temporary and worldly comforts are the root cause of pain and sorrow. One should rather pray to leave the body and attain liberation (moksha). Soul should have control over the body: the ultimate highness in one's life is to reach Lord Shiva's feet.
Legend has it that Manikkavacakar was appointed as minister by king Arimarttanar and sent to purchase 10,000 horses from Arab traders but spent the money building a temple in Tirupperunturai.
