Rajaraja didn't have 2 meikeerthis. 'Thirumagal pola' is the only one meikeerthi he had. 'Kandalur chalai' is the second line. Every year the meikeerthi grows by appending that year's victories.
The given text of Rajendra - I 's meikeerthi is from the middle. First few lines are missing. The first line is 'Thirumanni valara...'.
Then I guess, even 'Alaikadal neduvul palakalam seluththi' must also be that of Rajendhra II or III. or it is in middle of Rajendhra I's meikeerthi, right?
My understanding is, the meikeerthi is added or created after a great accomplishment. Gaingai kondathu oru maaperum seyal ( I may have used word inccorectly here) athepol kadaaram kondathum.
I think, I can expect a good response from all other members too, on this for debate and lets go on to Rajendhra's expendition towards Sindhu.
