Symplanicity is a concept developed by Michel Bogé, inspired by Carl Jung’s idea of synchronicity, to describe an acausal and atemporal relationship between the material world and the symbolic realm. While synchronicity emphasizes meaningful coincidences in time, symplanicity shifts this relation toward the intersection of planes of reality. Symplanicity often appears through symbolic lines of meaning on geographical maps.

Symplanicity should not be confused with coplanarity or symplanarity. In geometry and the sciences, these terms simply describe elements lying on the same physical plane or surface. Symplanicity takes this idea further by extending it into the metaphysical domain, suggesting that the plane itself can carry meaning. Connecting the dots on a map works much like connecting ideas in the mind: as alignments and patterns take shape, a new understanding of reality begins to emerge.
