Bhagavad Gita · 7.24

अव्यक्तं व्यक्तिमापन्नं मन्यन्ते मामबुद्धयः।परं भावमजानन्तो ममाव्ययमनुत्तमम्॥

avyaktaṁ vyaktim āpannaṁ manyante mām abuddhayaḥ paraṁ bhāvam ajānanto mamāvyayam anuttamam

The unintelligent think of Me, the unmanifest, as having come into manifestation, not knowing My supreme nature, which is imperishable and unsurpassed.
