  A general strategy is formulated for computing bound state spectra in the
framework of functional renormalisation group (FRG). Dynamical "coordinates"
characterising bound states are introduced as coupling parameters in the
$n$-point functions of effective fields representing the bound states in an
extended effective action functional. Their scale dependence is computed with
functional renormalisation group equations. In the infrared an interaction
potential among the constituting fields is extracted as smooth function of the
coupling parameters. Eventually quantised bound state solutions are found by
solving the Schr\"odinger eigenvalue problem formulated for the coupling
parameters transmuted into coordinates. The proposed strategy is exemplified
through the analysis of a recently published FRG study of the one-flavor chiral
Nambu--Jona-Lasinio model.
