Kṛṣṇa is the paramaḥ pumān, although there is no difference between Rāma and Viṣṇu and Nārāyaṇa and Kṛṣṇa. They are the same, same potency. Just like the candle, first candle, and lit up another candle, it is second candle. But the second candle is not less in power of lighting. The same. But still this is first, this is second. Similarly, kṛṣṇaḥ svayaṁ samabhavat paramaḥ pumān yo (Bs. 5.39). Kṛṣṇa is the original, kṛṣṇas tu bhagavān svayam. Ete cāṁśa kalāḥ puṁsaḥ kṛṣṇas tu bhagavān svayam (SB 1.3.28). All others, they're incarnation or kalā, but Kṛṣṇa is the avatārī, the source of all incarnation.
So bhakta-sane vāsa. Satāṁ prasaṅgān mama vīrya-saṁvido (SB 3.25.25). The kṛṣṇa-kathāḥ, or the discussion about the Supreme Personality of Godhead, becomes very pleasing, and satām, when they're discussed among the devotees. Nondevotees, he may go on speaking, but it is dry. It does not give any relish. Therefore it is advised, satāṁ prasaṅgān, one should discuss Kṛṣṇa consciousness amongst the devotees. So just contrary to this, Sanātana Gosvāmī says that:
- avaiṣṇava-mukhodgīrṇaṁ
- pūtaṁ hari-kathāmṛtam
- śravaṇaṁ na kartavyam . . .
Avaiṣṇava, who is not a Vaiṣṇava, Māyāvādī . . . Māyāvādī philosophy is very dangerous. Caitanya Mahāprabhu has personally said, māyāvādī haya kṛṣṇe aparādhī. They're offenders to Kṛṣṇa. Just like the literatures . . . what is that literature, Kṛṣṇa is black something?
Indian man: Viṣṇu-sahasra-nāma.
Prabhupāda: Huh?
Indian man: Some commentary by this Viṣṇu-sahasra-nāma.
Prabhupāda: Kṛṣṇa is unknown, a black thing. A Māyāvādī, great philosopher of this city, he has explained like that. The Māyāvādī philosopher, Dr. Radhakrishnan, "It is not to Kṛṣṇa." So the Māyāvādīs' only business is—because they're avaiṣṇava, not Vaiṣṇava—only business is to kill Kṛṣṇa. Sanātana Gosvāmī has, in his Hari-bhakti-vilāsa, has very strongly recommended that "Don't hear anything from . . . about Kṛṣṇa, from the Māyāvādīs or the avaiṣṇavas." Those who are follower, those who are advanced in Kṛṣṇa consciousness, they can protest. They can immediately chastise the rascal, "What you are nonsense speaking?" But a kaniṣṭha-adhikārī, he cannot challenge; therefore it is forbidden for them: not to hear, kaniṣṭha-adhikārī. For an advanced devotee, this Māyāvādī cannot do anything, but those who are neophyte, they become sometimes victim. Therefore, it is better to forbid them, not to hear.
