1978 Sikh–Nirankari clashes
The turning point in the Sikh-Nirankari relationship is believed to have come after Avtar Singh took over as the sect chief in 1943. He not only proclaimed himself “Satguru” but also introduced a book “Avtar Bani” and allegedly tried to copy Sikh symbols like starting the system of Sat Piare etc. He was successful in organising Nirankaris into a powerful sect. However, in his book “A History of The Sikhs”, Khushwant Singh noted that the fundamental difference between both was that the Nirankaris were worshiping gurus other than the 10 recognised by the Sikhs.
