9.18.44

उत्तमश्चिन्तितं कुर्यात् प्रोक्तकारी तु मध्यम: । अधमोऽश्रद्धया कुर्यादकर्तोच्चरितं पितु: ॥ ४४ ॥

uttamas cintitam kuryat prokta-kari tu madhyamah adhamo ’sraddhaya kuryad akartoccaritam pituh

uttamah
the best
cintitam
considering the father’s idea
kuryat
acts accordingly
prokta-kari
one who acts on the order of the father
tu
indeed
madhyamah
mediocre
adhamah
lower class
asraddhaya
without any faith
kuryat
acts
akarta
unwilling to do
uccaritam
like stool
pituh
of the father.

A son who acts by anticipating what his father wants him to do is first class, one who acts upon receiving his father’s order is second class, and one who executes his father’s order irreverently is third class. But a son who refuses his father’s order is like his father’s stool.
