Bhagavad Gita 7.24 — God's supreme nature
अव्यक्तं व्यक्तिमापन्नं मन्यन्ते मामबुद्धयः। परं भावमजानन्तो ममाव्ययमनुत्तमम् ॥
avyaktaṃ vyaktimāpannaṃ manyante māmabuddhayaḥ | paraṃ bhāvamajānanto mamāvyayamanuttamam ||
Meaning
The unwise think of me, the unmanifest, as one who has merely taken a form. They do not know my supreme nature, imperishable and unsurpassed.
