Abstract : In this essay, an ethnography of events was carried out during psicographic letters for loved ones sessions. The sessions were promoted in Florianópolis in a group that does not maintain any relationship to the Brasilian Spiritist Federation (FEB) and in São Paulo in a center and in a group both linked with FEB, were psychographic letters sessions where conducted. From observations of these sessions it was possible to make comparisons and to identify a manifestation of a variant of the traditional Kardecist spiritism. One of the interests was to show how these distinct kardecist spiritual sessions happen, payin attention to the way the medium writer promotes the contact between the spiritual and the earthly plane to produce the letters. We thus indentify two patterns: one from the events and one from the houses linked to FEB. This distiction made it possible to identify a psychographic agency coming from a traditional Kardecist spiritiest religious sistem, which organizes itself in independent federations and organizes large events of psychographic writting events open to the public.
