  The original results for the baryon-pion couplings in the large $N_c$ QCD can
be understood in a simpler way in the Hartree-Fock picture. The large $N_c$
relation and its $1/N_c$ correction between the heavy baryon-meson coupling and
the light baryon-meson coupling are emphasized. Application to the
baryon-$\rho$ meson interactions is straightforward. The implications of recent
experimental result for the strong coupling constants of the heavy baryon
chiral lagrangian are discussed.
