Bhagavad Gita 15.18

यस्मात्क्षरमतीतोऽहमक्षरादपि चोत्तमः।अतोऽस्मि लोके वेदे च प्रथितः पुरुषोत्तमः॥

yasmātkṣaramatīto'hamakṣarādapi cottamaḥ |ato'smi loke vede ca prathitaḥ puruṣottamaḥ ||

As I transcend the perishable and am even higher than the imperishable, I am declared to be the highest Purusha in the world and in the Vedas.

I am beyond comparison with the Eternal and the non-eternal; I am known as the Supreme Personality, the Highest God, by scriptures and sages.

Our plain-language meaning of this verse is waiting for scholar review.
