यस्मात्क्षरमतीतोऽहमक्षरादपि चोत्तमः। अतोऽस्मि लोके वेदे च प्रथितः पुरुषोत्तमः।।

yasmāt kṣaram atīto ’ham akṣarād api cottamaḥ ato ’smi loke vede ca prathitaḥ puruṣottamaḥ

yasmāt (because) kṣaram (the fallible) atītaḥ (transcendental) aham (I am) akṣarāt (to the infallible) api (also) ca (and) uttamaḥ (the best) ataḥ (therefore) asmi (I am) loke (in the world) vede (in the Vedas) ca (and) prathitaḥ (celebrated) puruṣa-uttamaḥ (as the Supreme Person).

Because I am transcendental, beyond both the fallible and the infallible, and because I am the greatest, I am celebrated both in the world and in the Vedas as that Supreme Person.

Kṛṣṇa defines His highest title: Puruṣottama. He explains that because He is transcendental to both the ‘Kṣara’ (the fallible material world) and the ‘Akṣara’ (the infallible spiritual world), He is celebrated as the Supreme Person. He is above both matter and spirit. This is the climax of the chapter. Kṛṣṇa distinguishes Himself from the individual souls (who are fallible) and the liberated souls (who are infallible). He is the ‘Uttama’ or the Best. This defeats the idea that God is just an impersonal force or that every soul is exactly equal to God. There is a hierarchy, and Kṛṣṇa is at the summit. By knowing Kṛṣṇa as the ‘Puruṣottama’, we find a concrete object for our devotion. He is not just an energy to be merged into; He is a Person to be loved. This understanding is the highest conclusion of the Vedas, and it simplifies our spiritual journey into a direct relationship with the Supreme.
