Vande Mataram to me signifies only the energy and passion our freedom fighters displayed. It is a song that brings to memory a picture of committed, united and determind Indians acting as one to achieve a set objective. To me it is not a song sung in the praise of any God but one that was sung to enthuse people and get them involved in a movement.
It is sad that some people refuse to sing it today. I have my doubts on their reasons for not singing it. That said, I think it must be left to the individual. Such things cannot, need not and should not be imposed.
