Darker Reality of Sikhism

The truth of Sikhism which was hidden from the world, only this much was told to us and the world that Sikhism is a very good religion which does not differentiate on the basis of caste and religion and when the world faces trouble then Sikhism is the first one to reach out for help, they organize langar, do not ask for any money, do not show off but the black British and British politicians did not tell how many difficulties Sikhism has gone through and in the matter of their religious book also, more has been told about Guru Granth Sahib only but most of the people do not know about the two other books written by their Guru and by history I do not mean 1984 but the story of 200 and 300 years ago, that time was hidden, in 1984 also wrong information, wrong things and false things were told.
