Buddhist Scriptures give two different descriptions about the location of Kapilavastu, the native place of Buddha. One description puts it near the Himalayas, while the other puts it in Mid-India. Whereas all the studies in the past assumed the former description to be true, the latter was never refuted. There was no way to reject one of them, and it remained an unsettled historical issue. This was resolved in this study by application of Geometry. The required information was gleaned from Buddhist scriptures and travel accounts of Chinese pilgrims. The results show that Kapilavastu was situated in South-Kośala region. This is interesting and important as it goes against the present belief that Buddha was born in Nepal.
