In a village a Bestal district in Madhya Pradesh, only two types of people live who belong to a tribal class. The first type is known as class A, while the other is known as class B. In that village, there is no other type of person except these two. The activities of both of these types of persons are governed by perfectly patterned norms of social behavior. Each person of the tribe has to obey the norms. They are rigid about this.
As far as marriage is concerned, the following norms are to be followed:
(i) The people of class A cannot marry any other member of their own class, though they can marry members of class B.
(ii) After being married, each male member ceases to be a member of that class in which he was born, but automatically becomes the member of the class to which his wife belongs.
(iii) As far as females are concerned, they remain the members of their own class after being married.
(iv) On birth, the child automatically becomes the member of his mother’s class.
(v) When any male member becomes a widower or a divorcee, then he again belongs to the group in which he was born.
(vi) Nobody can marry more than one person
