The basic grammar of the third and final Tamil Sangam is "Tholkappiyam" composed by "Tholkappiyar", who according to critics is referred as Rishi Jamadagni's brother "Sthiranadumagni" and uncle of Parshurama. He categorically uses a Prakrit (Tamil:Pagatham) Tadbhava "Mayakkam", which is the root of the word Maya(m). He says that the entire creation is a blurred flow between State of matter or "Pancha Bhutas". This concept of Maya is of the school of Agastya, who was the first Tamil grammarian and the guru of Tholkappiyar.
