The Ninth Sikh Guru. He was martyred by Emperor Aurangzeb for refusing to convert to Islam and for defending the right of Kashmiri Hindus to practice their own faith — people who were not even his own. He is called "Hind di Chadar" — the shield of India. His poetry in the Adi Granth meditates on impermanence, detachment, and the peace of the Name.
