Bhagavad Gita · 15.6

न तद्भासयते सूर्यो न शशाङ्को न पावकः।यद्गत्वा न निवर्तन्ते तद्धाम परमं मम॥

na tad bhāsayate sūryo na śhaśhāṅko na pāvakaḥ yad gatvā na nivartante tad dhāma paramaṁ mama

That supreme abode of mine is not illumined by the sun, nor by the moon, nor by fire. Those who reach it never return — that is my supreme dwelling.

— Bhagavad Gita 15.6
