The present paper analyses the Siddh Gosti, a composition of Guru Nanak to understand the interface of Guru Nanak’s philosophy with prevailing philosophical traditions of his time. The study views the composition as an effort on the part of the Guru to engage with and demolish the philosophical hegemony of an established belief system that held sway in Northwest India in order to make way for the establishment of his own philosophy. Guru Nanak does this by providing new interpretations of (...) constructs which the Siddhs and Naths concerned themselves with. These new interpretations were more practicable, socially relevant and humane as compared to the ways of the Siddh and Nath Yogi traditions thus making Sikhism a more acceptable religion. (shrink)
