శ్రీ నృసింహ మంత్ర రాజము

ఉగ్రం వీరం మహా విష్ణుం జ్వలంతం సర్వతోముఖం |

నృసింహం భీషణం భద్రం మృత్యు మృత్యుం నమామ్యహం ||

उग्रं वीरं महा विष्णुं ज्वलन्तं सर्वतो  मुखं | 

न्रुसिम्हम भीषणं भद्रं मृत्यु मृत्युम नमाम्यहम ||

"I surrender and bow to Lord Narasimha, who is ferocious and heroic, who is Maha Vishnu, radiant and glowing from all sides, who is omnipresent, who is terrific, who is adorable, who bestows auspiciousness and who is the death of death personified."

When recited with sincere devotion, the above Mantra Raja will come to the rescue of the person in times of need, sudden aberrations and obstacles in life.
