What to read after Bhagat Singh WHY I AM AN ATHEIST? (Other Letter)?

Bhagat Singh (1907 – 23 March 1931) was an Indian socialist revolutionary whose two acts of dramatic violence against the British in India and execution at age 23 made him a folk hero of the Indian independence movement.Bhagat Singh was an outstanding revolutionary and martyr of the Indian anti-colonial movement. He represented the youth who were dissatisfied with Gandhian politics and groped for revolutionary alternatives. Bhagat Singh studied the European revolutionary movement and was attracted to anarchism and communism. He became a confirmed atheist, socialist and communist. He realised that the overthrow of British rule should be accompanied by the socialist reconstruction of Indian society and for this political power must be seized by the workers. Bhagat Singh and B.K. Dutt enunciated their understanding of revolution in a statement made in connection with the Assembly Bomb case on 6th June, 1929:'By Revolution we mean that the present order of things, which is based on manifest injustice must change. Producers or labourers, in spite of being the most necessary element of society, are robbed by their exploiters of their labour and deprived of their elementary rights. The peasant who grows corn for all, starves with his family; the weaver who supplies the world market with textile fabrics, has not enough to cover his own and his children's bodies; masons, smiths and carpenters who raise magnificent palaces, live like pariahs in the slums. The capitalists and exploiters, the parasites of society, squander millions on their whims.'
