The project means HUGE MONEY to people like TR Baalu - that's why they are so keen on Setusamudram. We should not lose sight of this most important point.
Personally, I dont believe that Rama or Krishna are historical characters though I consider Mahabharata and Ramayana the greatest epics (even ahead of the Iliad / Odyssey) in the world and Rama epitomizes great qualities - love , strength, courage, righteousness, respect for elders ..!
For that matter it is my opinion that any historical person who claimed / claims that he had communicated with God / had a message from God is a LIAR!!!
