Srimad Bhagavatam Canto 04, Chapter 26, Text 22

SB 4.26.22

paramo ’nugraho dando
 bhrtyesu prabhunarpitah
balo na veda tat tanvi
 bandhu-krtyam amarsanah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
My dear slender maiden, when a master chastises his servant, the servant should accept this as great mercy. One who becomes angry must be very foolish not to know that such is the duty of his friend.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
It is said that when a foolish man is instructed in something very nice, he generally cannot accept it. Indeed, he actually becomes angry. Such anger is compared to the poison of a serpent, for when a serpent is fed milk and bananas, its poison actually increases. Instead of becoming merciful or sober, the serpent increases its poisonous venom when fed nice foodstuffs. Similarly, when a fool is instructed, he does not rectify himself but actually becomes angry.
