Subject matter of 'soul and body' is indeed redundant, but tip-toeing into its dangerous realm can reveal some devastating truth.
The belief that soul resides in body and after death leaves the body is universal. This departure to heaven or another body is said to take place either immediately, or after the decomposition of the body. The good thing about this ascent is the blessing of 'Separation of Church and State' in some societies, type I. In these societies a graveyard is set aside for the dead, the statues of some revered individuals are erected in the main squares, but people are left alone to continue with their daily lives.
However, there are some other societies, type II, in which the soul, immediately after death but before covering the grave, is briefly extracted for registration purposes, but it is quickly returned to the grave to dwell and live with corps until Judgment Day, thus leaving no choice but to firmly believe that the dead are alive in their graves.
In this mentality, the dead, whether influential or a simple member of the family, can extensively control the daily life of the people. On the other hand, people can demonstrate their allegiance by donations or simply cooking some food, normally sweet, and take it to the graveyard. Since the dead do not rise, donors, to save face, share it with the crowd.
The dead, on their part, make it up to the beloved ones left behind! For instance, a shred of rag tied to or rubbed against the fence round the grave of certain deceased individuals can do magic works, such as generating money if kept in one's wallet, or the soil supposedly gathered from the same grave can be used as a cure for all diseases.
Male teenagers in these societies are constantly reminded of the horrors of the death and encouraged to watch the burial rituals; consequently, they see or hear horrible stories regarding what happens during death, in the grave or aftermath. For example, a boy can see the placement of the body in the grave, the removal of the shroud to show the face of the corps, the placing of a relative's hand on the shoulder of the corps. Next, he sees the relative's mouth brought down to the ear of the body, while firmly shaking the corps, and then loudly recites a long passage beginning with the following sentence, of course, in a language unknown to the deceased. 'Hear me, (name), son/ daughter of (father's name), (three times),' and the rest of the long passage.
Perhaps, Avram Noam Chomsky can add this centuries-old phenomenon to his previous discovery, Universal Grammar!
