“He conquers the world, who patiently puts up with the abuse of his neighbours. He who controls his anger, as a horseman breaks an unruly horse, is indeed a charioteer and not he who merely holds the reins, but lets the horse go whither it would. He who sheds his anger just as a snake its slough, is a real hero. He who is not moved despite the greatest torments inflicted by others, will realize his aim. He who never gets angry is superior to the ritualist who faithfully performs for a hundred years the sacrifices ordained by scripture. Servants, friends, brothers, wife, children, virtue and truth abandon the man who gives way to anger. The wise will not take to heart the words of boys and girls.”
Sukracharya imparts wisdom to his daughter Devayani who is angry after being treated badly by her companion Sarmishta.
