Dadāmi buddhi-yogaṁ tam. Tam means "unto Him." Whom? Bhajatāṁ prīti-pūrvakam. Those who are engaged in devotional service with love and faith. Because God is within you. You haven't got to search out where is God. Īśvaraḥ sarva-bhūtānām, hṛdy antaḥ-sthaḥ (BG 18.61).
We have begun this chapter śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ . . . (SB 1.2.17).
(aside) You are sleeping, this boy.
Śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ. Anyone who is engaged in hearing about Kṛṣṇa . . . to whom? To Him, not those who are sleeping. Those who are actually hearing, śṛṇvatām. Śṛṇvatām means hearing, not sleeping. To such person. Bhajatāṁ prīti-pūrvakam, and engaged in devotional service. Buddhi-yogaṁ dadāmi tam, "I give intelligence." It doesn't require . . . if he's sincere, if he's actually a devotee, Kṛṣṇa will help him.
Guru-kṛṣṇa-kṛpā. Guru is secondary, another mercy of Kṛṣṇa. Kṛṣṇa is helping within and without. That without help is guru, Kṛṣṇa's representative. So Kṛṣṇa is always ready to help us, and when Kṛṣṇa is helping us, it is very easy to understand Him. Therefore a devotee is beyond all doubts. Beyond all doubts. There is no doubt. Not that blindly we are accepting Kṛṣṇa as the Supreme Personality of Godhead. No. We have got all our arguments, scientific, philosophical, anything. Then we accept Kṛṣṇa. That acceptance is nice. That is uttama-adhikārī.
Kaniṣṭha-adhikārī, madhyama-adhikārī and uttama-adhikārī. There are three stages of devotees—lower class, middle class and first class. The first-class devotee is without any doubt. The third-class devotee, he's accepting, he's accepting: "Here is God," that's all. But he has many doubts. The second class, he, although he has got doubts, he's accepting on the authority of Vedas. That is second class. And the first class, he knows perfectly well that "Here is God."
That is the . . . the sarva-saṁśayaḥ. Chidyante. They are beyond all doubts. "Yes, Kṛṣṇa, the Supreme Personality of Godhead. Here is Kṛṣṇa. In this temple here is my Lord is standing. He has very kindly, mercifully, He has come to accept my service." That is first-class devotee. Just like Caitanya Mahāprabhu: as soon as He saw Jagannātha in the temple, immediately fainted. "Here is My Lord; I was searching after."
So there are stages. So those who are first class . . . here it is stated ato vai kavayaḥ. Kavayaḥ means first class. Ato vai kavayo nityam. Perpetually, eternally. Bhaktiṁ paramayā mudā: devotional service. Transcendental, paramayā. The devotional service . . . for the third-class devotee, the devotional service is also third class.
And the . . . although third class, first class, second class, we are distinguishing, it is not ordinary, material first class, second class. Even in the spiritual world there is such divisions. The same division. Just like in the light, in the sunlight, there is division: the sunshine, the sun globe and the sun god. There are three divisions. It is not that because you are in the sunshine you know what is the sun globe or what is sun god. That is another stage.
Similarly, just to become a devotee on the devotional service, there are stages. Stages. That is kaniṣṭha-adhikārī, madhyama-adhikārī. So uttama-adhikārī, uttama-adhikārī first class. He's firmly convinced, "Kṛṣṇa is the Supreme Personality of Godhead." Nobody can deviate. He can convert others to understand Kṛṣṇa, that He's the Supreme Personality of Godhead, but nobody can convert him that Kṛṣṇa is not God. That is not possible. That is first class.
So here it is said: ato vai kavayo nityaṁ bhaktiṁ paramayā mudā vāsudeve bhagavati (SB 1.2.22). Therefore those who are actually in the knowledge of Kṛṣṇa consciousness, science of God, they firmly fixed up in the devotional service of Kṛṣṇa, Vāsudeva. Vāsudeve bhagavati. Then what about the third class? The third class also, if he stick to the devotional service according to the rules and regulation, vāsudeve bhagavati bhakti-yogaḥ nayojitaḥ . . . (SB 1.2.7). Nayojita means "Just begun." Janayaty āśu vairāgyaṁ jñānaṁ ca yad ahaitukam. Then that devotional service to Vāsudeva, Kṛṣṇa, will gradually help him how to become vairāgya, how to become detached with material attraction, and how to acquire knowledge about Kṛṣṇa. Everything will come.
So for the kaniṣṭha-adhikārī, we must stick to the principle. Gradually, everything will be revealed. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234). In the beginning, because we have got blunt material senses, we cannot understand what is Kṛṣṇa, what is Kṛṣṇa's service; ataḥ śrī-kṛṣṇa-nāmādi . . . what is Kṛṣṇa's chanting of name. We are thinking that this is chanting, just like we chant so many vibrations, this is also like that. We cannot understand. But if we take up all this devotional service in right earnestness to serve the Lord, then everything will be gradually revealed.
That is required. But if we become slack in following the rules and regulation, then we remain the third class. We cannot raise ourself to the second-class, first-class position. Therefore all doubts remain. This is the position.
