If we understand Kṛṣṇa tattvataḥ, not superficial . . . here the word is used yatas tattvāvabodhanam. Tattvāvabodhanam: "Kindly explain to me that bhakti-yoga by which we can fully understand the truth, Absolute Truth." Tattvāvabodhanam.
So how that tattva can be understood? That is explained by Kṛṣṇa, that janma karma ca divyaṁ me yo jānāti tattvataḥ (BG 4.9). So we have to understand Kṛṣṇa tattvataḥ, by truth. And how? We can understand that Kṛṣṇa says in the Bhagavad-gītā, bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). This is tattva word. So tattvāvabodhanam. Devahūti is asking Kapiladeva that, "Kindly describe that process of yoga by which we can understand in truth, tattvāvabodhanam, not superficially." Tattvāvabodhanam. And in another place the tattva is described in three ways: vadanti tat tattva-vidas tattvaṁ yaj jñānam advayam (SB 1.2.11). They are not different. That is, everything is tattva. Tattva . . . there are three kinds of tattva: brahmeti paramātmeti bhagavān iti śabdyate. This very thing, tattva, is described in three features: impersonal Brahman, localized Paramātmā, and at the end Bhagavān.
So understanding of Bhagavān means understanding of Brahman and Paramātmā. But understanding of Brahman or Paramātmā is not understanding of Bhagavān. Therefore the Brahmavādīs, the Paramātmavādīs, they are impersonalists. They cannot understand the Supreme Being, Personality of Godhead, Kṛṣṇa. They cannot understand. That is the defect. Therefore some yoga system, jñāna-yoga system or dhyāna-yoga system, and there is bhakti-yoga system. That bhakti-yoga system is the perfect. And jñāna-yoga system or dhyāna-yoga system, that is partial understanding, Paramātmā feature. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). In that way you can understand, you can come to the platform of understanding samaḥ sarveṣu bhūteṣu. But that is not perfection. Still you have to go. Samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām (BG 18.54). After realizing samaḥ sarveṣu bhūteṣu, this principle, then you will have to enter into the devotional service, parā-bhakti. Parā-bhakti means transcendental. Bhakti means parā. Bhakti does not mean material. Material . . . it looks like material activities, but it is not material activities. Just like the example can be given just like a man, a boy is flying kite. He is, what is called, the reel? Latai? So sometimes he brings down the kite and sometimes he allows the kite to go. There are two kind of playing. So similarly, the one kind of activities means you are becoming free from the resultant action of activities, and one kind of activity is you are becoming entangled.
