Kṣetra Kṣetrajña Vibhāga Yoga

Krishna introduces the decisive distinction: the field (kṣetra) — the body, the senses, the mind — and the knower of the field (kṣetrajña) — the witness consciousness that observes all of it. He who truly knows this distinction, knowing himself to be the knower and not the field, knows the truth of things. This is the jñāna that liberates.
