"There is some evidence to show that the association of Vasudeva with the Pāndya country is old. In the fourth century B.C. the grammarian Katyayana explains the word Pāndya as 'one sprung from an individual of the clan of the Pandus or the king of their country'. Katyayana therefore associates the Pāndya country with the Pandus or Pāndavas whom epic tradition intimately connects with Vasudeva."
