Bhagavad Gita 13.33

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

yathā prakāśayatyekaḥ kṛtsnaṃ lokamimaṃ raviḥ |kṣetraṃ 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.

As the one Sun illuminates the entire earth, so the Lord illuminates the entire universe.
