This article deals with the experience of a group of users and workers in mental health services in Natal-RN, Brazil, students of undergraduate courses in health and professors and researchers from the area interested in discussing topics and experiences in mental health. Based on schizoanalysis and its cartographic method, we argue that the group functions as group-thought to be immanent space of production of thought to life through a rhizomatic operation. For both, the cartography was traced in three lines of composition built on notes logbook of the authors. They are: Line 1 - Tensions between the legitimacy of the University as a place of true vehicle of thought and building a group-thinking; Line 2 - New ways to experience the crisis: "the party day" and the group with the duties of care and support; Line 3 - The spin of new ways of exist: the requirements for a homogeneous group to trigger heterogeneous movements. We hope this cartography contributes to the production of new mental health practices that insist on the power of madness and meetings in the invention of life.
