In April 1921, Mohandas Karamchand Gandhi wrote in his journal "Young India" about the need for an Indian flag, proposing a flag with the "charkha" or spinning wheel at the centre. The idea of the spinning wheel was put forth by Lala Hansraj, and Gandhi commissioned Pingali Venkayya to design a flag with the spinning wheel on a red and green banner, the red colour signifying Hindus and the green standing for Muslims. Gandhi wanted the flag to be presented at the Congress session of 1921, but it was not delivered on time, and another flag was proposed at the session. Gandhi later wrote that the delay was fortuitous since it allowed him to realise that other religions were not represented; he then added white to the banner colours, to represent all the other religions. Finally, owing to the religious-political sensibilities, in 1929, Gandhi moved towards a more secular interpretation of the flag colours, stating that red stood for the sacrifices of the people, white for purity, and green for hope.
