I am not qualified to say anything about the different between Buddhism and Bon as they are practised in your village — or in Nepal in general. Perhaps I can just say this: at first the Buddhists criticised the Bon priests for relying on the gods, and ignoring the laws of cause and effect — karma. They argued that it was not the gods, or the priests that have the power to make one’s life better, but one’s own actions and mentality. Later, when Bon became an organized religion, the Bonpos also stressed the importance of karma, rebirth and of reliance on one’s own mind as the path to liberation. Therefore both Buddhism and Bon now contain similar paths to liberation. Equally, throughout history neither Buddhists nor Bonpos have thought it wise to ignore the local gods and spirits. So perhaps there need not be too much conflict between these traditions.
