This manual is a second-hand book, enriched by the experiences of the literary critic. It began as a conference/debate and was later transformed into a book on balega's recommendation.By listing moral and cultural values in this manual, we cover the way of life, language, rabbinate, canon law and lega psychology. It paints the Mulega as a leading people and a model to follow in the DRC for the foundation of a peaceful and prosperous state based on the rule of law.Sociologists and anthropologists disguised as Catholic missionaries have described Lega society. The specificity of balega customs led them to draw a parallel between Lega mores and the Hebraic customs contained in the Holy Bible. It was this hypothesis that served as the guiding thread in Masudi Malumba Thimoté's research.Going back in time, the traces of the Balega paved the migratory route followed by the Balega to Egypt, via Ubundu, Kisangani, Kirika (Uganda) and Nigeria. It was in Egypt, therefore, that the Lega people came into being as a result of interbreeding between a Jew (Leka) and a black Ethiopian woman (Seyah).
