Bhagavad Gita · 13.34

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

yathā prakāśhayaty ekaḥ kṛtsnaṁ lokam imaṁ raviḥ kṣhetraṁ kṣhetrī tathā kṛtsnaṁ prakāśhayati bhārata

Just as one sun illuminates this entire world, so the knower of the field illuminates the entire field, O Bharata.
