So that Kṛṣṇa you cannot understand vedeṣu, simply by studying Vedic literature. Although the Vedas means, Vedānta means, to understand Kṛṣṇa. Vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). But unfortunately, because we do not take the shelter of Kṛṣṇa or His devotee, we cannot understand what is the purpose of Vedas. That will be explained in the Seventh Chapter. Mayy āsakta-manāḥ pārtha.... Mayy āsakta-manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ. Mad-āśrayaḥ. Asaṁśayaṁ samagraṁ māṁ yathā jñāsyasi tac chṛṇu (BG 7.1). If you want to understand Kṛṣṇa asaṁśayam, without any doubt, and samagram, and in full, then you have to practice this yoga system.
What is that yoga? Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). Mad-āśrayaḥ yogaṁ yuñj... Yogaṁ yuñjan, mad-āśrayaḥ. Mad-āśrayaḥ, this word is very significant. Mat means... "Either you take directly..."That is not very easy thing. "...shelter of Me, or one who has taken shelter of Me, you take shelter of him."
