6.. Sikh Lehar "The author deals with the Sikh religion and its domination by the capitalist Sikh class. While Sikh Gurus propagate Sikhism for the benefit of the Sikh masses, modern Sikh rulers exploit it for their own benefit. The author also compares Sikhism and Marxism. This is a critical analysis of the real and actual concept of the Sikh movement enshrined in Gurbani and its political reality." Kishan Singh ,1978.
