If you want real knowledge, take it from Bhagavān. Bhagavān uvāca. Then your knowledge is perfect. That is our process. We, we have taken Bhagavad-gītā as it is, and we are preaching. We don't preach anything else which Bhagavān does not say. Bhagavān says, man-manā bhava mad-bhakto mad-yājī mām . . . (BG 18.65). We are canvassing, "My dear sir, you just become a devotee of Kṛṣṇa. You always think of Kṛṣṇa." Kṛṣṇa says, man-manā bhava mad-bhaktaḥ. We say, "You just think of Kṛṣṇa." The same thing. There is no change. We do not interpret any way, "This man-manāḥ means this, and mad-bhaktaḥ means that." No. We don't do that. We present as it is. Therefore if Kṛṣṇa sees that, "One is presenting My message as I have given," then He is pleased. Therefore it is said, kintu prabhor yaḥ priya eva tasya. He has become very dear because he do not nonsensically . . . he does not nonsensically change the meaning that, "This meaning's that, this meaning's that." Why? When Kṛṣṇa has said, that is everything perfect. Why should I change it? That is guru-priya.
Suppose if you say something and if somebody takes it as it is and behaves like that, then you become pleased. And if you say to your son or to your servant something and he misunderstand and talks something else, then he becomes angry, "What this nonsense has understood?" Similarly, a guru does not change the word of Kṛṣṇa. Therefore he's called Bhagavān, servant Bhagavān. Kṛṣṇa is the master Bhagavān, master God, and the guru, who is serving Kṛṣṇa sincerely, he's the servant God. Therefore śāstra says, sākṣād-dharitvena samasta-śāstrair uktas tathā bhāvyata eva sadbhiḥ. In the morning also these boys, they sing, Narottama dāsa Ṭhākura, āra nā koriho mane āśā. If you have got a pure, bona fide guru, then whatever he says, you do it. You don't think of anything else. Āra nā koriho mane āśā (Narottama dāsa Ṭhākura). No more. That is all right.
So we have to receive knowledge from Bhagavān or from a person who is servant of Bhagavān, not that another imitation Bhagavān. Then you'll spoil your life. That will not help you. So Bhagavān says, atha te sampravakṣyāmi. Sam means samyak, "In full," full knowledge, not partial. Atha te sampravakṣyāmi. Pra means prakṛṣṭa-rūpe. Vakṣyāmi. Vakṣyāmi means "I shall speak." Tattvānām. Tattvānām . . . tattva is one. Absolute Truth, it cannot be two; but there are different phases of understanding the Absolute Truth. Therefore here it is plural number, tattvānām. Tattva is one. That is explained in another place: vadanti tat tattva-vidas tattvaṁ yaj jñānam advayam (SB 1.2.11). Although tattva is realized in different phases, three phases, brahmeti paramātmeti bhagavān iti śabdyate. Brahman, impersonal feature, brahmeti paramātmā. First localized feature, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). That is Paramātmā.
