There are some people who to go to Bengaluru to Delhi with open window. They see so many visions, scenes and all kinds of visions and darshans and reach Delhi. There are some people whose windows are closed, they also reach Delhi. There is one danger if your window is open, you may see some middle station and think that Delhi has come and get down. But the journey itself will be very juicy. For people whose window is closed, you will not get anywhere in the middle, you will reach Delhi for sure, but journey itself will be little dry. But both will reach Delhi.
