Historical facts are uniformally similar for everyone but their interpretation varies. Very few historians' interpretation agrees with each other's. Every historian has his own point of view.It keeps on changing with the passage of time. In fact, the past is interpreted in the light of the present and it is a continuing process. This is particularly correct about the Sikh history. There is not so much diversity of opinion in the interpretation of any other nation's history as it is in the case of Sikh history.
