The article discusses the complementarity and opposition of the Bon religion and Buddhism in Tibetan rituals. The Bon-po circumabulate sacred rites in a counterclockwise manner, contrasting Buddhism's clockwise method. One difference in the two religions are their approaches to Tibetan history, wherein Bon-po histographers claim that the Bon religion has been established in Tibet before Buddhism emerged. Another Bon-po claim is that the Buddha ?ākyamuni was a Bon-po teacher whose roots was within the lineage of Bon founder Gshen-rab Mi-bo.
