13.19 So it has been told Krishna speaks

इति क्षेत्रं तथा ज्ञानं ज्ञेयं चोक्तं समासतः
मद्भक्त एतद्विज्ञाय मद्भावायोपपद्यते

iti kṣhetraṁ tathā jñānaṁ jñeyaṁ choktaṁ samāsataḥ
mad-bhakta etad vijñāya mad-bhāvāyopapadyate

So the field, and knowledge, and what is to be known, have been told in brief. My devotee, understanding this, comes to my own state.

Explanation

The summary, and a small word doing a lot.
