Muṇḍaka Upaniṣad 3.1.7

3.1.7

bṛhac ca tad divyam acintyarūpaṃ sūkṣmāc ca tat sūkṣmataraṃ vibhāti.
dūrāt sudūre tad ihāntike ca paśyatsv ihaiva nihitaṃ guhāyām.

7. Vast, heavenly, of unthinkable form,
And more minute than the minute, It shines forth.
It is farther than the far, yet here near at hand,
Set down in the secret place [of the heart], even here among those who behold [It].
