One unattained dream of Ponniyin selvan was to bring back the indra haram and mani mudi of pandya kings which was with king mahinda of sri lanka.He died without attaining that objective.
But his son the greatest ever tamil(probably indian)ruler rajendra removed that black mark.He attacked rohana.Mahinda as usual ran into forest.Rajendra chased him and got the indra haram and manimudi.He crowned his son in madurai.
And there are many towns in name of madhuranthakam.Many chola kings were called as mathuranthakan.What does that mean?
Mathura-mathurai anthakan-yeman
(Chinna paluvettarayar's name was kalanthaka kandar,meaning yema of yema)whenever madhurai was burnt chola kings gave themselves that title it seems.
