sarvabhūteṣu yenaikaṃ bhāvam avyayam īkṣate avibhaktaṃ vibhakteṣu tajjñānaṃ viddhi sāttvikam
Translation
That by which one indestructible Being is seen in all beings, inseparate in the separated, know thou that knowledge as pure.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
Sattvic knowledge is defined as seeing the one imperishable reality, undivided, within all the apparently separate beings — a non-dual seeing that looks past multiplicity to unity. This is essentially chapter 13’s culminating insight, recognizing the same field-knower everywhere, recast here as the top tier of a threefold epistemology rather than as a standalone realization.
