Dear Shri Ravi,
In all the discussions going on here about god, theism, agnosticism, etc., I feel we have two major groups or approaches. Some people are very sure that God exists and that the religious scriptures, advice from elders and Gurus, pravachanams, etc., tell you the correct method for knowing that God. So, for them, the tourist spot (destination in your analogy) is surely there and the bus route is what the religious scriptures, advice from elders and Gurus, pravachanams, etc., tell.
But don't you think there is a possibility of some others who may have lost their confidence or trust in what the religious scriptures, advice from elders and Gurus, pravachanams, etc., tell, and so would like to find out for themselves whether that tourist spot exists at all, and if it does, which bus route takes you fastest and most comfortably there? I suggest that you read the thread "Doubts about Hindu religion expressed by a swamiji in the making". This man went on to become a famous personage and champion of Hinduism but, nevertheless, he had doubts and that shows, at least to my mind, that getting such doubts is nothing sacrliegious but perhaps a signal of right progress, imho.
