Thanks to Bhante Yuttadhammo, Nina, Robert, et al...
I'm still absorbing all of this but still feel joy at the many examples
of kusala citta here.

The authors of the PED attribute the definition of pu~n~na as cleansing

The more common definition is closer to, "merit, good, goodness,
meritorious action" per A.K. Warder.

With Thanks & Metta,
