ŚVETĀŚVATARA UPANISHAD · 6.14

न तत्र सूर्यो भाति न चन्द्रतारकं नेमा विद्युतो भान्ति कुतो ऽयम् अग्निः ।
तम् एव भान्तम् अनुभाति सर्वं तस्य भासा सर्वम् इदं विभाति ॥

na tatra sūryo bhāti na candratārakaṃ nemā vidyuto bhānti kuto ’yam agniḥ ।
tam eva bhāntam anubhāti sarvaṃ tasya bhāsā sarvam idaṃ vibhāti ॥

The sun does not shine there, nor the moon and the stars, nor these lightnings, and much less this fire. When he shines, everything shines after him; by his light all this is lightened.

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