In plain words
The gods once asked Prajāpati: 'By which mantras, when the god is praised with them, does he become glad and show us his own self? Tell us, Lord.' And Prajāpati answered them like this: 'Om — u — Om: he who is truly the divine Lord Narasiṃha, and who is also Brahmā — to him; the Lord who is also the syllable Om — to him, hail, hail. Om — sa — Om: he who is Narasiṃha, and who is the four measures of Om — to him, hail, hail. Om — va — Om: he who is Narasiṃha, and who is every Veda with its branches and its ancillary lore — to him, hail, hail. Om — to — Om: he who is Narasiṃha, and who is the five sacred fires — to him, hail, hail. Om — mu — Om: he who is Narasiṃha, and who is the sacred utterances earth, sky, and heaven — to him, hail, hail. Om — kha — Om: he who is Narasiṃha, and who is the eight guardians standing at the world's directions — to him, hail, hail. Om — nṛ — Om: he who is Narasiṃha, and who is the eight Vasus — to him, hail, hail. Om — si — Om: he who is Narasiṃha, and who is the Rudras — to him, hail, hail. Om — ha — Om: he who is Narasiṃha, and who is the sun-gods, the Ādityas — to him, hail, hail. Om — bhī — Om: he who is Narasiṃha, and who is the eight wandering planets — to him, hail, hail. Om — ṣa — Om: he who is Narasiṃha, and who is earth, water, fire, air, and space, the five elements themselves — to him, hail, hail. Om — ṇa — Om: he who is Narasiṃha, and who is time itself — to him, hail, hail. Om — bha — Om: he who is Narasiṃha, and who is Manu, the first lawgiver — to him, hail, hail. Om — dra — Om: he who is Narasiṃha, and who is death — to him, hail, hail. Om — mu — Om: he who is Narasiṃha, and who is Yama, who governs the dead — to him, hail, hail. Om — tyu — Om: he who is Narasiṃha, and who is Antaka, the one who brings all things to their end — to him, hail, hail. Om — mu — Om: he who is Narasiṃha, and who is the very breath of life — to him, hail, hail. Om — tyu — Om: he who is Narasiṃha, and who is the sun — to him, hail, hail.

Om — sya — Om: he who is Narasiṃha, and who is every living soul — to him, hail, hail. Om — ha — Om: he who is Narasiṃha, and who is simply everything — to him, hail, hail. With these, Prajāpati told the gods: praise the god constantly with these thirty-two mantras, and he will be pleased and will show you his own self. So it is for anyone: praise the god constantly with these mantras, and you will see the god, you will see everything, and you will pass into immortality — for anyone who knows this. Here ends the Great Upaniṣad.

[32] Thus Prajāpati spoke those [mantras] to them: whoever praises the deity constantly with these thirty-two mantras — thereupon the deity becomes pleased and shows his own self. Therefore, whoever praises the deity constantly with these mantras, he sees the deity, he sees everything, and he attains immortality — whoever knows this. Thus [ends] the Great Upaniṣad.
