Part of 18: Mokṣha Sanyās Yog — मोक्षसंन्यासयोगअध्येष्यते च य इमं धर्म्यं संवादमावयोः।ज्ञानयज्ञेन तेनाहमिष्टः स्यामिति मे मतिः॥
adhyeṣhyate cha ya imaṁ dharmyaṁ saṁvādam āvayoḥ jñāna-yajñena tenāham iṣhṭaḥ syām iti me matiḥ
And he who studies this sacred dialogue of ours, by him I shall have been worshipped through the sacrifice of wisdom; such is my conviction.
There are four kinds of sacrifice -- Vidhi? Japa? Upamsu and Manasa. Vidhi is ritual. Japa is recitation of a Mantra. Upamsu is Japa done in a whisper. Of the four kinds? JnanaYajna or the wisdomsacrifice comes under Manasa and is, therefore, the highest. The Gita is eulogised as a JnanaYajna. He who studies this scripture with faith and devotion will attain the fruit that is eal to that of performing JnanaYajna or meditation on a deity and the like.
