"Prominent amongst the Tat Khalsa reformers were scholars such as Bhai Kahn Singh of Nabha and the prolifically versatile writer Bhai Vir Singh. Closely associated with them was the Englishman M. A. Macauliffe.*? Together with others who shared the same attitudes and concerns, these authors were responsible for moulding and recording a version of the Sikh tradition which remains dominant in intellectual circles to the present day. It is important to remember that, when we read literature dealing with the Sikh tradition, we are usually reading perceptions which have been refracted through a Tat Khalsa lens. The reminder is essential if we are to achieve genuine detachment in any analysis of Sikh history, doctrine, or behaviour. Repeatedly we must draw attention to the impressive success achieved by scholars and writers associated with the Singh Sabha movement, for only thus can we hope to disengage our own interpretations from their continuing influence."
