satvik i agree wid u dat 2day & from da time of British Sri Lanka was known as Ceylon & also as Sinhaldweep. but i hav read in Jayasi's Padamavat dat Sinhaldweep was sumwhere btwn Orissa & Bengal region & Sri Lanka was also known as Lanka only at dat time. he has mentioned it as Lanka dweep & alongwid 6 oder dweep, &even he mentioned Jamboodweep not as whole of India but only N.India.
1 more interesting thing i hav read in sum history book (wen i went 2 Delhi 4 da coaching of UPSC exams & also i luv history after science , literature & geography) dat 2days inhabitants of Sri Lanka r called Sinhals & their ancestors came from da Bengal region.
