Hi that link says Jambudvipa is in the bible, but the reference they use is not the bible. Can you please provide me with the page and line where Jambudvipa is referenced in the bible?
The Bible says something along these lines "The merchants who having go to Jambudvip in the Southern sea to fetch great and precious gems feel refreshed after hearing the siblime lore of the Buddha". The comment made before 1890 says its Ceylon. The comment was made before the Buddha history revised incorrectly around 1890.
This is another reference with the correct history.
And another."Seih-lan is situated in Southern India, and is a large island in the sea, on the south east ,coast,its circumference been about 1000 le (300 miles) having in the centre lofty mountains ;on the coast the land in low and marshy . The country is characterised by much rain and constant thunder. The hills and valleys are beautifully ornamented with flowers and trees of great variety and beauty, the cries of animals rejoicing together fill the air with gladness,and the landscape abounds with splendour. In the forests are many elephants and the native use them instead of draught oxen or horses. The people are all of the Buddhist religion ;it is said that Buddha was born here....
