Bhagavad-gītā is the essence of all Vedic literature. Sarva-gavopanisadam(?). It is the essence of all Vedic literature. Therefore Kṛṣṇa says. . . What is the purpose of Vedas? You may be very learned scholar in Vedas, then what you have learned, Vedānta? Vedānta means the last knowledge of Vedas. So Vedānta is, Kṛṣṇa is explaining in the Bhagavad-gītā, vedānta-kṛd vedānta-vit cāham.
- sarvasya cāhaṁ hṛdi sanniviṣṭo
- mattaḥ smṛtir jñānam apohanaṁ ca
- vedaiś ca sarvair aham eva vedyo
- vedānta-vit vedānta-kṛd ca aham
- (BG 15.15)
So the summary is there. Kṛṣṇa is sitting, sarvasya ca aham, hṛdi, within the heart, sanniviṣṭaḥ, "I am seated there." Īśvaraḥ sarva-bhūtānām (BG 18.61). And He is giving intelligence and forgetfulness. Why one is forgetful of Kṛṣṇa and why one is conscious of Kṛṣṇa? That is also due to Kṛṣṇa. One who has tried to forget Kṛṣṇa, then Kṛṣṇa is giving him opportunity to forget Kṛṣṇa. One who is trying to know Kṛṣṇa, then Kṛṣṇa is giving intelligence to know Kṛṣṇa. This is the process. Kṛṣṇa is there. If you want to know Kṛṣṇa, then Kṛṣṇa will give you intelligence how to know Him. If you want to forget Kṛṣṇa, then He will give you, mislead you in such a way that you will forever forget Kṛṣṇa. Sarvasya cāhaṁ hṛdi sanniviṣṭaḥ (BG 15.15).
That is also explained in the Bhagavad-gītā: tān ahaṁ dviṣataḥ krūrān kṣipāmy ajasram andha-yoniṣu (BG 16.19). Those who are asuras, demons, trying to defy the existence of God, Kṛṣṇa, Kṛṣṇa is putting him in such circumstances, in such family, in such society, in such community, in such country that he will have no opportunity to know Kṛṣṇa. Tān ahaṁ dviṣa. . . Because he is envious of Kṛṣṇa, wants to forget Kṛṣṇa, so Kṛṣṇa is putting him in such circumstances. And one who is little eager to know Kṛṣṇa, then Kṛṣṇa is giving the intelligence.
- teṣāṁ satata-yuktānāṁ
- bhajatāṁ prīti-pūrvakam
- dadāmi buddhi-yogaṁ taṁ
- yena mām upayānti te
- (BG 10.10)
Everything is said there. Teṣāṁ satata-yuktānām. Anyone who is twenty-four hours engaged in. . . How he is engaged? Bhajatām: simply for bhajana. Bhajana means worshiping, "How to worship Kṛṣṇa." Satata-yuktānām, and twenty-four hours anxious, "How to serve Kṛṣṇa? How to serve Kṛṣṇa?" To become mad after Kṛṣṇa, such person. Just like Caitanya Mahāprabhu says, śūnyāyitaṁ jagat sarvaṁ govinda-viraheṇa me (Śikṣāṣṭaka 7): "I see everything vacant being separated from Govinda." This is called love. So, of course, it is not possible to come to that position like Caitanya Mahāprabhu. That is mahā-bhāva, mahā-bhāva. It is not for any human being to come to that stage. But Caitanya Mahāprabhu has shown how to become mad after Kṛṣṇa by His life when He was in Jagannātha Purī, Caitanya. At night He would go out and fall down on the sea or somewhere. Nobody knows. The door was closed, and still, He would get out and go, and, "Where is Kṛṣṇa? Where is Kṛṣṇa?" Then His assistants, secretaries, would go out and find out Him. So for eighteen years He was in that way in Jagannātha Purī. That is called mahā-bhāva.
