What is Sikhism and who is a Sikh? This book surveys the history of the sect, showing how various circumstances influenced the criteria by which people could be identified. One belief is that Sikhism is the complete acceptance of the teachings of the tenth Guru, Gobind Singh. According to the tradition, a true Sikh must be of the Khalsa, the community founded by Guru Singh; yet, there are many who belong to families with a Khalsa heritage but no longer observe the tradition in its full rigor. And, there are many others who regard themselves as Sikhs but do not follow the discipline of the Khalsa, such as the so-called Sahaj-dhari Sikhs. McLeod examines these discrepansies and disagreements, offering a new discussion and analysis of who and what defines Sikhism.
