Bhagavad Gita 15.12

यदादित्यगतं तेजो जगद्भासयतेऽखिलम्।यच्चन्द्रमसि यच्चाग्नौ तत्तेजो विद्धि मामकम् ॥१५.१२॥

yadādityagataṃ tejo jagadbhāsayate’khilamyaccandramasi yaccāgnau tattejo viddhi māmakam

That light which resides in the sun, illuminating the whole world; that which is in the moon and in the fire—know that light to be Mine.
