CHĀNDOGYA UPANISHAD · 3.11.3

न ह वा अस्मा उदेति न निम्लोचति ।
सकृद् दिवा हैवास्मै भवति ।
य एताम् एवं ब्रह्मोपनिषदं वेद ॥

na ha vā asmā udeti na nimlocati ।
sakṛd divā haivāsmai bhavati ।
ya etām evaṃ brahmopaniṣadaṃ veda ॥

And indeed to him who thus knows this Brahma-upanishad (the secret doctrine: of the Veda) the sun does not rise and does not set. For him there is day, once and for all.
