Caitanya Mahāprabhu said, prithivite achhe yata nagarādi grām sarvatra prachār haibe more nāma. This is His prophecy. In the entire world, in all the villages and towns, everywhere, my preaching, this saṅkīrtana will spread. You will please practice it. This is very simple and easy. Sthāne sthitāḥ śruti-gatāṁ tanu-vāṅ-manobhir (SB 10.14.3). Stay situated in your place. Whatever work you are doing, there is no need to give it up. But engage in the chanting of the Names of Kṛṣṇa, and from the mouth of the pure devotee hear the glories of the Supreme Lord Kṛṣṇa. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam (SB 7.5.23). So you all kindly hear from the lips of the pure devotee. Don't hear from those who are professionally engaged in reciting the glories of Kṛṣṇa for maintaining their livelihood. Hear from the lips of those who have renounced everything for the Supreme Lord. Satāṁ prasaṅgān mama vīrya-saṁvido bhavanti hṛt-karṇa-rasāyanāḥ kathāḥ (SB 3.25.25). By hearing from the lips of such devotees, one very quickly develops devotional service provided one practices good conduct of life.
Ādau śraddhā tataḥ sādhu-saṅgo . . . (indistinct) To practice devotional service, one must accept the following principles: utsāhān, one must be very enthusiastic that in this very life one will attain the Supreme Lord; dhairyāt, with patience, one must not become disturbed, one must execute the principles as given in the revealed scriptures; utsāhān dhairyāt niścayād and one must be confident that since I have taken shelter of the Supreme Lord and the Supreme Lord guarantees that anyone who takes shelter of Him gets relieved from all the sinful reactions.
