As we have been discussing at various points, Kalki collected materials and compressed everything and put into PS. His main idea should have been to bring such points to reader's attention than suppressing them because the story-line was not covered under the era!
Soodamani Vihara was one such example... but there existed a Buddist Vihar during RR's period according to other scholars!
Easana siva pandhithar was the Chief priest of Rajarajeswaram. His name figures as Poonguzhali's uncle...
Sundarachozhan aadoorasalai constructed by Kundavai after RR ascended to throne in 985 AD... it also figures..
Ironically, Sundarapperuamal koil was Sundhara Chozhan Vinnagaram - from where our Govindarajan Kapisthalam (GK) Mooppanar hailed and almost was to have become the Prime Minister of India!
