143. Is there in this world any man so restrained by humility that he does not mind reproof, as a well-trained horse the whip?
144. Like a well-trained horse when touched by the whip, be ye active and lively, and by faith, by virtue, by energy, by meditation, by discernment of the law you will overcome this great pain (of reproof), perfect in knowledge and in behaviour, and never forgetful.
DHAMMAPADA, Chapter 10. Punishment
