This stage proposal has as one of its hypothesis the idea that is productive thinks the initiation ritual of female Ticuna Indians as a repression machine of desiring-production of neophytes who pass by it. Everything indicates that this repression would fall in alliances with non-humans that happened in the time of myth and that the ritual, through a "cathartic prophylaxis", would avoid. Non-human beings appear in the ritual in the figure of the masked, trying to steal the girls to them. We may ask if this alliance relationship "demoniacal," that happens with the maskeds in the ritual, would have implications for the desires and affections that are expected of the girls and the relationship that they will establish with their relatives? In this sense, can we say that the ritual pullout of neophytes hair is a kind of "symbolic castration"? The research mainly focuses on the ritual steps, the songs, the counseling and the manipulation of the bodies of the girls and the participants of the ritual. But also can not do without a memory analysis of older people in relation to ritual and an observation of the relationship between the girls and their closest relatives. It is intended to realize an analysis of the affects - such as, anxiety, aggression, fear, desire, etc. - that pervade and compose the bodies of the girls and their relatives.
