This paper proposes the Relational Emergence Model (REM) as a generative extension of Relational Quantum Mechanics (RQM). While RQM defines physical states as relative correlations between systems,it does not explicitly address how such correlations are dynamically produced. The REM introduces emph{differentiation} as a generative process through which relational distinctions become articulated and subsequently stabilizedinto effective classical structures via decoherence. More precisely, differentiation is formalized as a bipartition-selecting map$mathcal{D}$---not a unitary operator, but a descriptive structural selection---that produces explicit system--observer correlations from apre-relational Hilbert space. Environmental decoherence then suppresses off-diagonal coherences, stabilizing effectively classical facts. Rather than asserting any equivalence between quantum theory and Buddhist philosophy, this work identifies a structural correspondence between relational quantum interpretations and the concepts of dependent origination(prat={i}tyasamutp=ada) and emptiness ('{s}={u}nyat=a). The central contribution of REM is a shift from the emph{definition} ofrelational states to the emph{modeling of the generation} of relational structure itself.
