In plain words
Brahman alone is, one without a second; no plurality exists here. To know both Kṣetra—the field—and Kṣetrajña—the one who knows it—is what is called Jñāna.
Close to the Sanskrit
Brahman is one alone, Advaya—non-dual; here no multiplicity whatsoever exists. Knowledge of Kṣetra, the field, and Kṣetrajña, the knower of the field—that knowing is called Jñāna.
