Bhagavad Gita 13.34

यथा प्रकाशयत्येकः कृत्स्नं लोकमिमं रविः।क्षेत्रं क्षेत्री तथा कृत्स्नं प्रकाशयति भारत ॥१३.३४॥

yathā prakāśayatyekaḥ kṛtsnaṃ lokamimaṃ raviḥkṣetraṃ kṣetrī tathā kṛtsnaṃ prakāśayati bhārata

Just as the one sun illuminates the entire world, so too does the Lord of the field (Supreme Self) illuminate the entire field, O Arjuna.
