Acharya Prashant: Chandogya Upanishad — Chapter 3, part 11, verses 2 and 3:
न वै तत्र न निम्लोच नोदियाय कदाचन । देवास्तेनाहंसत्येन मा विराधिषि ब्रह्मणेति ॥ ३.११.२ ॥
na vai tatra na nimloca nodiyāya kadācana | devāstenāhaṃsatyena mā virādhiṣi Brahmaṇeti || 3.11.2 ||
Never does this happen there; never did the sun set there nor did it rise. Oh Gods, by this, by my assertion of the Truth may I not fall from Brahm. ~ Chandogya Upanishad 3.11.2
न ह वा अस्मा उदेति न निम्लोचति सकृद्दिवा हैवास्मै भवति य एतामेवं ब्रह्मोपनिषदं वेद ॥ ३.११.३ ॥
na ha vā asmā udeti na nimlocati sakṛddivā haivāsmai bhavati ya etāmevaṃ Brahmopaniṣadaṃ veda || 3.11.3 ||
Verily, for him, the sun neither rises nor sets. He who thus knows this secret of the Vedas, for him, there is perpetual day. ~ Chandogya Upanishad 3.11.3
