SB 6.8.14

durgesv atavy-aji-mukhadisu prabhuh

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
May Lord Nrsimhadeva, who appeared as the enemy of Hiranyakasipu, protect me in all directions. His loud laughing vibrated in all directions and caused the pregnant wives of the asuras to have miscarriages. May that Lord be kind enough to protect me in difficult places like the forest and battlefront.
