This is a National Geographic Special episode " Keepers of the Dream." It occured to me that the rituals of these ancient and obviously able people were imortant to them, believing that the activities, useless as it seems to outsiders, strengthened their belief and guarantied preservation of paradise. The House to house walking is a similar ritualized activity, with little real impact on the intendet aim, and puzzling to say the least, to onlookers.
The film had scenes of a remote rock oasis, that you'd swear was sculpted by a genius landscape architect, but clearly a natural formation, and the place where Petro glyphs, cave paintings were done thousands of years before the fictional Mid-east garden of eden could have existed.
but rituals did and still do
one August campaign finished, next: more ritual walking .
