Sarveṣām apy aghavatām idam eva suniṣkṛtam. Suniṣkṛtam. Nāma-vyāharaṇaṁ viṣṇor yatas tad-viṣayā matiḥ. Now the Viṣṇudūta says, sarveṣām apy aghavatām. Aghavatām means those who are sinful. Agha means sin, and vatām means who are possessors of sinful life. Sarveṣām, "Of all kinds of sinful persons," sarveṣām apy aghavatām idam eva suniṣkṛtam, "this is the only process by which he can become immediately freed from the reaction." Idam eva suniṣkṛtam. What is that? Nāma-vyāharaṇam: "Simply chanting this mantra," vyāharaṇa. Nāma-vyāharaṇaṁ viṣṇoḥ. Not that any other name.
The foolish persons, they say that, "You chant any name, any name," sometimes demigods' names, sometimes his beloved's name. They think that any name, chanting . . . because the Māyāvādīs, they think that everyone is God—"Even the demigods, they are God. I am God. You are God"—therefore they say that any name you chant and you will be freed. But that's not a fact. Here it is said clearly, vyāharaṇaṁ nāma viṣṇoḥ: "only the Supreme Personality of Godhead Viṣṇu's name," viṣṇu-sahasra name. There are list of one thousand names of Viṣṇu.
So Kṛṣṇa and Viṣṇu, the same, and it is stated in the śāstras that by chanting one thousand holy names of Viṣṇu you can get the result of chanting . . . once chanting the name of Rāma. If you, say, only chant Rāma, by this chanting, you immediately get the result of chanting thousand times Viṣṇu's name. And by chanting three times Lord Rāma's name you get the result of chanting once Kṛṣṇa's name. Therefore by chanting Kṛṣṇa's name you get all the good results.
Caitanya Mahāprabhu therefore recommends this. He recommends; not that He has manufactured. He recommends the śāstric injunction: harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21). So the harer nāma or viṣṇu-nāma or devotional service to Viṣṇu . . . Śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23). You should always remember this, because sometimes rascals mislead that "Any name."
In Bengal it is very popular. There is a party, they chant kālī-kīrtana, "Kālī, Kālī, Kālī," imitation. Or there are so many so-called avatāras. There was another rascal, he added his wife's name. (laughter) Yes. And the rascal, (chuckles) foolish scholars also accepted.
