 This, states Pashaura Singh, may have been the result of the traditional Sikh schools in Amritsar of 18th– and 19th–century which included Vedanta as a standard part of the Sikh learning.According to W. H. McLeod – a historian and Sikhism scholar, the "Suraj Prakash" contains "somewhat higher proportion" of Sikh history, but it is mostly ahistorical mythology and untrustworthy source of Sikh history.Max Arthur Macauliffe extensively but selectively used the "Suraj Prakash", in cooperation with Kahn Singh Nabha, for his six-volume "The Sikh Religion" series that presented Sikh scriptures and history to the Western world in early 20th-century.
