"Nanak's religion consisted in the love of God, love of man and love of godly living. His religion was above the limits of caste, creed and country. He gave his love to all, Hindus, Muslims, Indians and foreigners alike. His religion was a people's movement based on modern conceptions of secularism and socialism, a common brotherhood of all human beings. Like Rousseau, Nanak felt 250 years earlier that it was the common people who made up the human race. They had always toiled and tussled for princes, priests and politicians. What did not concern the common people was hardly worth considering. Nanak's work to begin with assumed the form of an agrarian movement. His teachings were purely in Punjabi language mostly spoken by cultivators. He appealed to the downtrodden and the oppressed peasants and petty traders as they were ground down between the two mill stones of Government tyranny and the new Muslims' brutality. Nanak's faith was simple and sublime. It was the life lived. His religion was not a system of philosophy like Hinduism. It was a discipline, a way of life, a force, which connected one Sikh with another as well as with the Guru."
