Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Prahlada Maharaja loudly chanted the holy name of Lord Nrsimhadeva. May Lord Nrsimhadeva, roaring for His devotee Prahlada Maharaja, protect us from all fear of dangers created by stalwart leaders in all directions through poison, weapons, water, fire, air and so on. May the Lord cover their influence by His own transcendental influence. May Nrsimhadeva protect us in all directions and in all corners, above, below, within and without.
