Kṛṣṇa is sitting within your heart, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). Kṛṣṇa is with you, but you do not know. But as soon as you try to chant and hear, hear Kṛṣṇa's name, then immediately the cleansing of your heart begins, ceto-darpaṇa-mārjanam. Then bhava mahā-dāvāgni-nirvāpanam (CC Antya 20.12), as soon as your heart is cleansed . . . Heart is cleansed means you understand that you are not this material body. That is cleansing of heart. Everything is going on on this misunderstanding that "I am this body"—"I am Indian," "I am American," "I am this," "I am that." This is the grossest type of misunderstanding. So that becomes clear. Then you stand on your own position, brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54). There are so many things we'll gradually follow. Therefore if we chant Kṛṣṇa's name without any offense . . . There are ten kinds of offenses, but in the beginning, even there is offense, you go on chanting and gradually, as your heart will be cleansed . . . That is explained by Śrī Caitanya Mahāprabhu.
- ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpanaṁ
- śreyaḥ-kairava-candrikā-vitaraṇaṁ vidyā-vadhū-jīvanam
- ānandāmbudhi-vardhanaṁ prati-padaṁ pūrṇāmṛtāsvādanaṁ
- paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam
- (CC Antya 20.12)
So if you follow the instruction and if we chant, even though we do not understand in the beginning what is the effect of chanting Hare Kṛṣṇa mantra, but it will show its effect if you go on chanting. Just like I began this movement in America. I did not ask them anything; I simply invited them, "Please come and chant with me." And just see the result. It is practical. I never bribed them, nor I showed any magic. I simply asked them, "Chant Hare Kṛṣṇa." And see the result. It is practical.
Acyutānanda: Another question: "Why is oṁ not figured in your . . . (indistinct) . . .? All should come to the banner of oṁ instead of praying to so many gods. By doing so there would be unity throughout the land."
Prabhupāda: Kṛṣṇa says, praṇavaḥ sarva-vedeṣu (BG 7.8): "I am the oṁkāra in all Vedic mantras." Oṁ tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti. Oṁkāra is as good. That is also Kṛṣṇa. So either you chant oṁkāra or Kṛṣṇa, there is no difference. But in the śāstras it is recommended that you chant Hare Kṛṣṇa, not oṁkāra. So you have to accept śāstra. And Caitanya Mahāprabhu practically demonstrated. He was chanting Hare Kṛṣṇa. Kṛṣṇa-varṇam, kṛṣṇaṁ varṇayati, Hare Kṛṣṇa. So we have to follow the śāstra and the great saintly person. Otherwise there is no difference between oṁkāra and Kṛṣṇa. But because śāstra recommends harer nāma harer nāma (CC Adi 17.21), we have to accept it.
