ŚVETĀŚVATARA UPANISHAD · 6.17

स तन्मयो ह्य् अमृत ईशसंस्थो ज्ञः सर्वगो भुवनस्यास्य गोप्ता ।
स ईशे अस्य जगतो नित्यम् एव नान्यो हेतुर् विद्यत ईशनाय ॥

sa tanmayo hy amṛta īśasaṃstho jñaḥ sarvago bhuvanasyāsya goptā ।
sa īśe asya jagato nityam eva nānyo hetur vidyata īśanāya ॥

He who has become that, he is the immortal, remaining the lord, the knower, the ever-present guardian of this world, who rules this world for ever, for no one else is able to rule it.
