PURPORT

Dhruva Maharaja's becoming angry, overwhelmed with grief, and envious of the enemies was not incompatible with his position as a great devotee. It is a misunderstanding that a devotee should not be angry, envious or overwhelmed by lamentation. Dhruva Maharaja was the King, and when his brother was unceremoniously killed, it was his duty to take revenge against the Yaksas from the Himalayas.
