A chiral Lagrangian for massive pseudoscalar mesons is derived from the QCD-generating functional by the chiral bosonization method. The low energy region in the fermionic integral where ehiral noninvariant quark fluctuations dominate, is described by two mass parameters -an invariant cutoffA and a
