Abstract: Quark-condensate contributions to m dyn , the quark mass generated by the dynamical breakdown of chiral symmetry, are shown to arise from only the first two terms of the operator-product expansion (OPE) for the appropriate O ( g 2 ) nonperturbative vacuum expectation value. Since the m | p | expansion parameter of the OPE is unity on the gauge-invariant p = m dyn propagator pole, such truncation of OPE contributions is an essential support to the calculation of m dyn .
