Systemic laterality (left/right)

Systemic laterality is a convention used by many Constellation facilitators —documented by authors such as Joan Garriga, Brigitte Champetier, and Bertold Ulsamer— that assigns symbolic meaning to the left and right sides of the client (or a representative) in the Constellation space.

Predominant convention (not absolute):

Client's left side: maternal, feminine, past, unconscious, receptive dimension. The mother and maternal lineage tend to be placed here.

Client's right side: paternal, masculine, future, conscious, action-oriented dimension. The father and paternal lineage tend to be placed here.

Possible bases: Systemic laterality resonates with (1) neurological findings on hemispheric lateralization —right hemisphere related to affect, early bonding, symbolic maternal (managed by the body's left hemisphere); left hemisphere with reason, language, symbolic paternal—; (2) ancient cultural symbolic traditions —in many cultures, left is 'feminine-receptive,' right is 'masculine-active'—.

Important caveat: It is NOT an absolute rule. Some Constellation facilitators work by inverting or without this convention. What matters is internal coherence in each session and the reading of how the field moves, not the imposition of rigid patterns.

Clinical diagnosis: When a client spontaneously chooses to place the mother on the right side and the father on the left, this inversion often reveals something systemic —mother with a paternal function, father with a maternal function, or inversion of parental roles—. It is information, not an error.
