Krishna introduces a staggering metaphysical addition to the previous definition. He says: O descendant of Bharata (bhārata), you must clearly understand (viddhi) that I Myself am also the Knower of the field (kṣetra-jñaṃ cāpi māṃ). But unlike you, I am the Knower situated perfectly within *all* bodies and all fields simultaneously (sarva-kṣetreṣu). Furthermore, the actual, factual understanding of these two entities—the field of activity and the Knower(s) of the field (kṣetra-kṣetrajñayor jñānaṃ yat)—that precise comprehension is what I consider to be true, supreme knowledge (taj jñānaṃ mataṃ mama).
