In the Bhagavad-gītā it is taught what is God, what is nature of God and who is God, and what are these living entities, we living entities, and what is our relationship. These things are taught in the Bhagavad-gītā. We have to find out. Kṛṣṇa, the Supreme Personality of Godhead, He says,
- ahaṁ sarvasya prabhavo
- mattaḥ sarvaṁ pravartate
- iti matvā bhajante māṁ
- budhā-bhāva-samanvitāḥ
- (BG 10.8)
So Kṛṣṇa is the origin of everything. Ahaṁ sarvasya prabhavaḥ. Sarvasya means including all other demigods. Even Brahma, Lord Śiva, and even Viṣṇu, they are emanations from Kṛṣṇa. We have got in the Vedic literature how Kṛṣṇa is the original person. Therefore Arjuna accepted, paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12). And the Gosvāmīs, the Six Gosvāmīs, they have analyzed Kṛṣṇa's characteristics, Nārāyaṇa's characteristics, Lord Śiva's characteristics, Lord Brahmā's characteristics. They have analyzed very scrutinizingly everything and they have found it that Kṛṣṇa is cent percent God. Nārāyaṇa is ninety-six percent God, Lord Śiva is eighty-four percent God, Lord Brahmā is eighty-seven percent God. Of course, those who have studied Vedic literature, especially the book named Bhakti-rasāmṛta sindhu which we have translated into English, Nectar of Devotion or The Science of Devotion... So you have to learn from the Vedic literatures what is God, what are the living entities, what is their relationship, what is our ultimate goal of life. But everything is very nicely and concise form is stated in the Bhagavad-gītā.
