More recently, I demonstrated against racism with a comrade who was a turbaned Sikh. He addressed a rally and spoke about Muslim-Sikh unity. I understand that there is now a Gurdwara as near as Preston. Sikhs are part of British society. My google search for "Sikh" images found pictures of Sikhs on British streets and one picture of a uniformed Sikh standing behind the Queen. In Leicester, we bought Indian food from a Sikh shop to bring back to Lancaster where our neighbours are Muslims, not Sikhs or Hindus.
It is good to know that there will be a Sikh community in the Terran Empire. When a Terran Naval spaceship is almost destroyed in battle with Merseians, Commander Ranjit Singh in Section Two assumes command - becomes acting captain - unless and until a superior officer turns out to be alive. Ranjit orders Ensign Flandry in Section Five to man a gun in case the enemy returns. Flandry replies, "'Aye, aye, sir.'" (Ensign Flandry, London, 1976, p. 203)
Later, the text confirms that acting Captain Ranjit Singh is bearded. Correct, uncut hair being one of the five Signs of Sikhism. That is all that we are told but it is enough to confirm that, like the Mahayana Buddhist Sangha and the Jerusalem Catholic Church, the Sikh Khalsa thrives under Emperor Georgios.
