Śrīmad-Bhāgavatam · Text 6.4.11
Who is speaking and story frame
आतिष्ठत सतां मार्गं कोपं यच्छत दीपितम् ।
पित्रा पितामहेनापि जुष्टं व: प्रपितामहै: ॥ ११ ॥
ātiṣṭhata satāṁ mārgaṁ
kopaṁ yacchata dīpitam
pitrā pitāmahenāpi
juṣṭaṁ vaḥ prapitāmahaiḥ
The path of goodness traversed by your father, grandfather and great-grandfathers is that of maintaining the subjects [prajās], including the men, animals and trees. That is the path you should follow. Unnecessary anger is contrary to your duty. Therefore I request you to control your anger.
