The domestication of ayahuasca as Daime meant a certain indigenization of Acrean Christianity. Narrative moments like grasping the vine in Peru make clear that these forces lie across the boundary of the “other world” — in this case, the mysterious forest, and that there is power (as well as danger) in the crossing of these boundaries. Irineu Serra’s casa, situated between forest and city, continues to be relevant not only to the people who participate in it, but also for Acre’s efforts to identify and celebrate its own cultural identity.
