  I discuss the comparison of the current theoretical calculations of
epsilon'/epsilon with the experimental data. Lacking reliable ``first
principle'' calculations, phenomenological approaches may help in understanding
correlations among different contributions and available experimental data. In
particular, in the chiral quark model approach the same dynamics which
underlies the Delta I = 1/2 selection rule in kaon decays appears to enhance
the K -> pi pi matrix element of the Q_6 gluonic penguin, thus driving
epsilon'/epsilon in the range of the recent experimental measurements.
