In this article, the author develops a clinical practice of Meshing-Network-Linking within a group psychoanalytic approach to linking. He defines the characteristics of the network with reference to the theory of complexity. The birth of a network cannot be decreed. The privileged indication of a network practice concerns anamorphoses. They are transitional phases in the individual and group life cycle (perinatality, peri-adolescence, peri-senescence), and the breaches/troubles that bring into play individual, family group, institutional or social containing capacities in transformation. The author proposes a metapsychology of the meshing-network liking with reference to his conceptualisation of the meshing, demeshing and remeshing of psychic contents. He likens the architecture of the rhizome, (Deleuze, Guattari), with that of the spongenetwork which seems to him to offer a better account of the topology of network linking. The example of the mythical Rasta network developed from action research training and supervision, illustrates a topologicaland topographical modelisation of the remeshing of network linking. The process of transformation is manifested by the emergence of a meta-containing capacity. Network linking has a function of narrative support. It is a praxis of the ephemeral. The practice of supervisions is justified for supporting the transfero- countertransférential issues mobilised in Meshing-Network-Linking.
