It's very interesting to notify that in any practical case studying of curse or other presumed esoteric facts, always two classical point of view about the subject are found. The medical and the occult initiates one. The early medicals statements about the subject tell about some pathological mass paranoia. The expert said that someone's acting's, whose fully implicating himself into acts and words without any restraining center or environment, will automatically generate an advantageous general atmosphere to beliefs... New Caledonians doctors still studying this main theory. Some Melanesian natives folks ritual are very similar to other primitive esoteric cult in south pacific and further. We can easily conclude that those practices are common to islander populations.
The recurrences of some spirituality forms, in spite of a far geographic situations and many cultural diverging between the archipelagos, can be explained by a social reason. Without tutoring authority in society, thought habits will involving an hight sense of mysticism (collective pathology inherent, also a mass psychological phenomenon) Then usages and cultural habits will include a phantasmagoria's polytheistic universe and other primitive beliefs or cults referring to paganism as well...
THIS IS the medical point of view...
