Did Shakespeare say that he wrote "Hamlet" after the death of Hamlet himself ? The Greek historian Megasthenes has stated that Chandragupta Maurya was the 138 King in the lineage of Shri Krishna. This means that Shri Krishna did exist in the bygone era and that Mahabharat did really occur. It was a custom to keep a track of the Kings lineage. The Chinese traveller confirms the above. Manahbharat being a true account of a occured War, such lineages are seen to be recorded. Archaeological excations has discovered the submerged city of Dwaraka. This is the same Dwaraka as mentioned in the Mahabharat. [ The city of Dwaraka has been reckoned to have drowned in between 2000-3000 B.C.] The astronomical recordings in the Mahabharat "epic" and other scriptures (Bhagwat), given the correct positions of the planets and stars during that time. How could a work of fiction be proved using mathematical tools ?
