Bhagavad Gita Chapter 13, Verse 19

इति क्षेत्रं तथा ज्ञानं ज्ञेयं चोक्तं समासतः | मद्भक्त एतद्विज्ञाय मद्भावायोपपद्यते ||

iti kṣetraṁ tathā jñānaṁ jñeyaṁ coktaṁ samāsataḥ mad-bhakta etad vijñāya mad-bhāvāyopapadyate

Thus the field, knowledge, and that which is to be known have been briefly described. My devotee, having understood this, attains My nature.

Krishna summarizes what has been taught: the field (kṣetra), knowledge (jñāna), and that which is to be known (jñeyaṁ—the Supreme). 'Iti kṣetraṁ tathā jñānaṁ jñeyaṁ coktaṁ samāsataḥ'—thus the field, knowledge, and that which is to be known have been briefly described. 'Mad-bhakta etad vijñāya'—My devotee, having understood this. 'Mad-bhāvāyopapadyate'—attains My nature. When you understand the distinction between field and knower, when you understand the qualities that lead to knowledge, when you understand the Supreme—you attain the nature of the Supreme. This means you realize your true nature—the knower, not the field. You recognize yourself as the eternal consciousness, not the temporary body. This is liberation—freedom from identification with the field, realization of your true nature as the knower.
