May Lord Nṛsiṁhadeva, who appeared as the enemy of Hiraṇyakaśipu, 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.
