BṚHADĀRAṆYAKA UPANISHAD · 3.7.8

यो दिवि तिष्ठन् दिवो ऽन्तरो यं द्यौर् न वेद यस्य द्यौः शरीरं यो दिवम् अन्तरो यमयत्य् एष त आत्मान्तर्याम्य् अमृतः ॥

yo divi tiṣṭhan divo ’ntaro yaṃ dyaur na veda yasya dyauḥ śarīraṃ yo divam antaro yamayaty eṣa ta ātmāntaryāmy amṛtaḥ ॥

'He who dwells in the heaven (dyu), and within the heaven, whom the heaven does not know, whose body the heaven is, and who pulls (rules) the heaven within, he is thy Self, the puller (ruler) within, the immortal.'

F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
