FromĀ Pronoia -- How the Whole World is Conspiring to Shower You With Blessings by Rob Brezsny, page 236:
"In the Babemba tribe of South Africa, when a person acts irresponsibly or unjustly, he is placed in the center of the village, alone and unfettered. All work ceases, and everyone in the village gathers in a large circle around the accused. Then each person in the tribe speaks to the accused, one at a time, recalling the good things the person had done in his life. Every experience that can be recalled with detail and accuracy is recounted. All his positive attributes, good deeds, strengths, and kindnesses are recited carefully. This ceremony often lasts for several days . At the end a joyous celebration takes place, and the person is symbolically and literally welcomed back into the tribe."
