If you study "Shree Brahma-Purana", you will be very happy to know, that "Shree NaraSimha-Mahatmya" is a part of "Shree Brahma-Purana".
I will cite some brilliant Verses from "Shree NaraSimha-Mahatmya" in my blog, just laconic posts in 3-6 Verses.
भक्त्या दृष्ट्वा तु तं देवं प्रणम्य नरकेसरीम् /
मुच्यते पातकैर् मर्त्यः समस्तैर् नात्र संशयः
"Shree Brahma-Purana", 55.5: "By devoutly visiting Bhagavan Shree NaraSimha and by bowing to Lord Shree NaraSimha one is liberated from all the sins. There is no doubt in this".
नरसिंहस्य ये भक्ता भवन्ति भुवि मानवाः /
न तेषां दुष्कृतं किंचित् फलं स्याद् यद् यद् ईप्सितम्
"Shree Brahma-Purana", 55.6: "Those men on the earth who are the bhaktas of Bhagavan Shree NaraSimha, incur no sin at all. The will have all their wishes and dreams fulfilled"
तस्मात् सर्वप्रयत्नेन नरसिंहं समाश्रयेत् /
धर्मार्थकाममोक्षाणां फलं यस्मात् प्रयच्छति
"Shree Brahma-Purana", 55.7: "Hence, by all means one should resort to Bhagavan Shree NaraSimha, since Lord Shree NaraSimha grants kama, artha, dharma and Moksha".
