Bhagavad Gita Chapter 18, Verse 70

अधियेष्यते च य इमं धर्म्यं संवादमावयोः | ज्ञानयज्ञेन तेनाहमिष्टः स्यामिति मे मतिः ||

adhiyeṣyate ca ya imaṁ dharmyaṁ saṁvādamāvayoḥ jñāna-yajñena tenāham iṣṭaḥ syām iti me matiḥ

And he who will study this righteous conversation between us, by that sacrifice of knowledge, I will be worshipped by him. Such is My opinion.

Krishna gives the final assurance about studying the Gita. 'Adhiyeṣyate ca ya imaṁ dharmyaṁ saṁvādamāvayoḥ'—and (ca) he who (yaḥ) will study (adhiyeṣyate) this righteous conversation (imam dharmyam saṁvādam) between us two (āvayoḥ). 'Jñāna-yajñena tenāham iṣṭaḥ syām iti me matiḥ'—by that sacrifice of knowledge (jñāna-yajñena tena), I (aham) will be worshipped (iṣṭaḥ syām) by him. Such is My opinion (iti me matiḥ). This is the final assurance: whoever studies this righteous conversation between Krishna and Arjuna (the Bhagavad Gita), by that sacrifice of knowledge, Krishna will be worshipped by him. Studying the Gita is itself a form of worship—a sacrifice of knowledge. When you study the Gita with devotion, you are worshipping Krishna through knowledge. This is the assurance: study the Gita, and Krishna will be worshipped by you.
