ghnantam bahu sapantam va
My dear followers, never treat a learned brahmana harshly, even if he has sinned. Even if he attacks you physically or repeatedly curses you, always continue to offer him obeisances.
Lord Krsna offers this instruction not only to His personal associates but to all those who claim to be followers of the Supreme Personality of Godhead.
