Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: O King, Vrtrasura, the commander in chief of the demons, advised his lieutenants in the principles of religion, but the cowardly demoniac commanders, intent upon fleeing the battlefield, were so disturbed by fear that they could not accept his words.
