The part "weak immorality" which I've marked off above with two asterisks
should be "weak morality" according to the reading of the CSCD text:
itthili"nga.m dubbalakusalena pati.t.thaati (As 322) --- the feminine sex is
(re-)established through weak moral action or conduct. I would prefer
"strong immoral conduct" for "grossly immoral conduct" (balava-akusalena) in
contrast to "weak immoral conduct" (dubbala-akusalena).
