Maheshwar Bhakthas - 63 Nayanmargal

[viggop]

Pandya queen was Mangayarkarasi.She was also a devout shiva bhaktha and is also considered as a nayanmar.I dont think it was sampandhar who will curse the king to become sick.
It was sampandhar who called "Thirunavukarasar" by the name "appar"(a father).That is because sampandhar was a kid and appar was quite old enough to be his father.

Gnanasampandhar will come to present day chennai(mayilapur etc.). he is said to have broght back a dead girl to life in mayilapur
