  We calculate the masses of the vector and axial-vector mesons as well as the
nucleon and the delta resonance in the chiral symmetry restored vacuum. This is
accomplished by separating the quark operators appearing in the QCD sum rules
for these hadrons into the chiral symmetric and symmetry breaking parts
depending on the contributions of the fermion zero modes. We then extract the
vacuum expectation values of all the separated parts of the quark operators
using the QCD sum rule relations for these hadrons with their vacuum masses and
widths. By taking the chiral symmetry breaking parts to be zero while keeping
the symmetric operators to their vacuum values, we obtain the chiral symmetric
part of the hadron masses. We find that the masses of chiral partners, such as
the $(\rho,a_1)$ and $(K^*,K_1)$, become degenerate to values between 500 and
600 MeV in the chiral symmetry restored vacuum, while parity partners
$(\omega,f_1)$ that are chiral partners only in the limit where the
disconnected diagrams are neglected remain non-degenerate with masses
$(655,1060)$ MeV, respectively. The masses of the nucleon and the Delta are
also found to reduce to about 500 and 600 MeV, respectively, in the chiral
symmetric vacuum. This shows that while chiral symmetry breaking is responsible
for the mass difference between chiral partner, both the meson and baryon
retain non-trivial fraction of their masses in the chiral symmetry restored
vacuum.
