In 1906, the Transvaal government promulgated a new Act compelling registration of the colony's Indian and Chinese populations. At a mass protest meeting held in Johannesburg on 11 September that year, Gandhi adopted his still evolving methodology of Satyagraha (devotion to the truth), or nonviolent protest, for the first time.[79] According to Anthony Parel, Gandhi was also influenced by the Tamil moral text Tirukkuṛaḷ after Leo Tolstoy mentioned it in their correspondence that began with "A Letter to a Hindu".[80][81] Gandhi urged Indians to defy the new law and to suffer the punishments for doing so. Gandhi's ideas of protests, persuasion skills and public relations had emerged.
