Definitions for "Congruence"
A term coined by Walt Freitag for play which merges two or more GNS modes. As he puts it: "A congruent decision is a decision made by a participant (GM or player) during play that cannot, on the basis of the visible behavior resulting from the decision, be categorized as belonging to a specific mode of decision-making enumerated by the underlying model. In the context of the GNS model there are exactly four possible congruencies, representing the four combinations of two or more modes for which a decision may be ambiguous." Others have disagreed over whether sustained congruent play is possible. References: GNS and "Congruency"

State of being unified, and completely sincere, with all aspects of a person working together toward an outcome” (O'Connor, 230). “When goals, thoughts and behavior are in agreement” (Andreas, 332).
In general relativity, a congruence (more properly, a congruence of curves) is the set of integral curves of a (nowhere vanishing) vector field in a four-dimensional Lorentzian manifold which is interpreted physically as a model of spacetime. Often this manifold will be taken to be an exact or approximate solution to the Einstein field equation.
In the theory of smooth manifolds, a congruence is the set of integral curves defined by a nonvanishing vector field defined on the manifold.
