The name of the Buddha Shakyamuni is translated as "Sage of the Sak family." However, whether the Buddha was really a Sak, no one has proven in science so far. Based on some similarities between Buddhism and Tengrianism, as well as on the striking similarity between Buddhist culture and Saka style, Kazakh archaeologist Arman Umarkhodzhiev puts forward a theory about the blood relationship of the Shakyamuni Buddha family with the prosperous Saka tribes that lived in the same era on the territory of modern Kazakhstan. For confirmation of their theory, the researchers go on an expedition to Nepal.
