Star, you have fallen in to hole that you wished to avoid!
If the Vedas are an obsolete form of the Quran is the message in Vedas also from the one God that you and I believe in?
Obsolete means older, does God have a habit of changing his views regularly! Like Hollywood does he come out with sequels – Terminator, Terminator 2 etc?
Lastly can you tell me why the Lord who sent 124000 Prophets should have decided to stop with Mohamed the Prophet?
I sincerely don’t want to embarrass or offend you. I want just to make you realize that in matters of faith there is no rationale just faith. Faith makes you think that everything that your religion teaches is right and every thing that someone else’s religion teaches him totally wrong ! It is the same for a Hindu , a Muslim , Christian to anyone else . The way out lets each man follow what his faith demands of him .
