This video is taken from the udham singh movie, udham singh gave the ultimate sacrifice to his country. He came to London and killed governor of Punjab odwer for killing thousands of innocent people on vaisakhi day in Punjab 1919 at jallianwala bagh Amritsar. While the british were trying to divide india, udham singh was trying to keep all the citizens united after coming to the uk he used the alias mohammed ram udham singh azad much to the british disgust.
This song is about tolerance and equality written by the great sufi (muslim) saint baba bulleh shah. His teachings are very relevant to the world today.
