Abstract : This thesis focuses specifically over the culture of Kaingang people, considering shamanism, cosmology and religion. It approaches the Kaingang shamanic complex, seeking to relate religion, the savage forest and the spirituality in the formation of the Kaingang specialists from the Xapecó's Indigenous Land: kujá, benzedor (blesser) and remedieiro (medicine man). The research was carried out in four villages: Sede, Olaria, Baixo Samburá and Pinhalzinho. Starting from the bibliographic research and through continuous contacts with indigenous interlocutors, following the paths already been written by other non-indigenous researchers who analysed the Kaingang shamanism. At the beginning of the thesis are presented general information about my people, through information from mythology, history and archaeology. Follow it we present the different processes of formation of each specialist, some them requiring much more of spirituality and contact with their spiritual guides jagre, and the spirits of the savage forest, that is, the owner of the bush. Every specialist who moves to the savage forest needs to ask permission of the owner to enter, whether to collect medicines from the bush or to purify. Each one is chosen to follow the path of wisdom, spirituality in relation to the customs and traditions of the Kaingang people. And each specialist has the tribal brand Kame or Kanhru, asking to have experts from both sides, so the cosmological balance is kept in order. The specialists in healing kujá, benzedor and remedieiro have a spiritual relation with the savage forest, with the owner of it, venhkagta and jagre, the difference in the formation of each one is the form of choice of the expert, the time of duration and the requirements that involve the processes of formation of each one. The kujá is considered the strongest, because it prepares for much longer, through eleven specific stages, the "correntes" (chains). The formation of the benzedor is different from the kujá, this can last for a maximum of five years and only a few benzedors mentioned that they received spiritual guides. The masters who teach the traditional knowledge to the kujá and to the benzedor are older specialists (kófa). The formation of the therapist can last for a maximum of 3 years and this may vary, since these specialists are not chosen by other specialists along with their spiritual guides, their formation depends on the person's own initiative to wish to learn from the Kaingang sages about the power of healing from the medicines from the savage forest.
