Anyway, the chanting is so auspicious, Caitanya Mahāprabhu has given His benediction, ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpaṇam (CC Antya 20.12). We are suffering in this material world because we are not cleansed of our understanding or of our heart. The heart is not cleansed. So this chanting will help us to cleanse the heart.
- śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ
- puṇya-śravaṇa kīrtanaḥ
- hṛdy antaḥ stho abhadrāṇi
- vidhunoti suhṛt satām
- (SB 1.2.17)
Chanting is so nice that as soon as you take to chanting, or hear about Kṛṣṇa—the chanting is also hearing about Kṛṣṇa—so immediately the cleansing process begins, ceto-darpaṇa-mārjanaṁ (CC Antya 20.12). And as soon as our heart is cleansed, bhava-mahā-davāgni-nirvāpaṇam, then we become free from the blazing fire of this material existence. So chanting is so auspicious, therefore Parīkṣit Mahārāja here, Śukadeva Gosvāmī says, varīyān eṣa te praśnaḥ kṛto loka-hitaṁ nṛpa SB 2.1.1. In another place also, Śukadeva Gosvā..., Sūta, Sūta Gosvāmī says, yat kṛtaḥ kṛṣṇa-sampraśno yayātmā suprasīdati. When the great saintly persons in the Naimiṣāraṇya inquired about Kṛṣṇa, he replied like that. Yat kṛtaḥ kṛṣṇa-sampraśnaḥ: "Because you have inquired about Kṛṣṇa, it will cleanse your heart, yenātmā suprasīdati. You will feel a very transcendental bliss, comfort, within your heart."
So varīyān eṣa te praśnaḥ kṛto loka-hitam (SB 2.1.1). Loka-hitam. Actually our, this movement is the prime welfare activities to the human society, loka-hitam. It is not a business. Business means my hitam, my benefit only. It is not. It is Kṛṣṇa's business. Kṛṣṇa's business means Kṛṣṇa is for everyone; therefore Kṛṣṇa's business is meant for everyone. We therefore welcome everyone. There is no distinction. "Come here and chant," loka-hitam. And a sādhu, a saintly person should always think of loka-hitam. That is the difference between sādhu and ordinary man. Ordinary man, he thinks only of himself, or expanded himself, for family, for community, for society, for nation. These are all expanded selfishness. Expanded. When I am alone, I am thinking of my benefit only. When I am little grown up, I think of my brothers and sisters, and when I am little advanced, I think of my family. Little advanced, I think of my community. Little advanced, I think of my country, my nation. Or I can think of the whole human society, internationally. But Kṛṣṇa is so big that Kṛṣṇa includes everyone. Not only human society, animal society, bird society, beast society, tree society—everything. Kṛṣṇa says, ahaṁ bīja-pradaḥ pitā: (BG 14.4) "I am the seed-giving father of all these forms."
