  A method for constructing a complete set of relativistic three-quark states
in light front dynamics is implemented for the nucleon, N$^*$(1520) and
N$^*$(1535). This approach facilitates constructing states containing virtual
antiquarks. A physical interpretation is provided in terms of transition
amplitudes from quark to quark-gluon or quark-Goldstone boson Fock states of
chiral dynamics generated by flux tube breaking expected in QCD at intermediate
distances.
