ŚVETĀŚVATARA UPANISHAD · 4.17

एष देवो विश्वकर्मा महात्मा सदा जनानां हृदये संनिविष्टः ।
हृदा मनीषा मनसाभिकॢप्तो य एतद् विदुर् अमृतास् ते भवन्ति ॥

eṣa devo viśvakarmā mahātmā sadā janānāṃ hṛdaye saṃniviṣṭaḥ ।
hṛdā manīṣā manasābhikḷpto ya etad vidur amṛtās te bhavanti ॥

That god, the maker of all things, the great Self, always dwelling in the heart of man, is perceived by the heart, the soul, the mind;--they who know it become immortal.
