"Those who represented the reformist sector of the Singh Sabha movement came to be known as the Tat Khalsa (the ‘True Khalsa’ or the ‘Pure Khalsa’). Opposing them, and increasingly disadvantaged by the strength of Tat Khalsa ideals and determination, were the conservatives of the so-called Sanatan Khalsa. By the turn of the century the exponents of Tat Khalsa theory had asserted an effective claim to interpret the nature of tradition and to enunciate the approved pattem of Sikh behaviour."
