"Kholobar" is a unique book. It is the first ever publication on the proto-Bulgarian high priests ( the kholobar) - a special knowledge that has been determined to be passed on by word of mouth. Spas Mavrov has taken the risk to reveal some of this sacral knowledge on paper being one of the few ( or even maybe, the only) living principles of the alst Bulgarian shaman Doytcho who has yielded up his soul many years ago. In "Kholobar" we see how the priest of Tng-Ra the one and only God of proto-Bulgarians (heralds of the first monotheistic religios doctrine in the world), served Him through sacred principles and rules and no commandments except the warning "Heaven is watching".
