In this connection, there is a statement in the Fourth Canto of the Śrīmad-Bhāgavatam, wherein King Pṛthu says to his subjects: "My dear citizens, please note that the Supreme Personality of Godhead, Hari, is actually the deliverer of all fallen conditioned souls. No demigod can perform this act of delivering the conditioned souls, because the demigods themselves are conditioned. A conditioned soul cannot deliver another conditioned soul. Only Kṛṣṇa or His bona fide representative can deliver him. The Ganges water which is flowing down from the toe of Lord Viṣṇu falls upon the earthly planet and other planets and thereby delivers all the conditioned sinful living entities. So what need is there to speak of the deliverance of persons who are always engaged in the service of the Lord? There is no doubt about their liberation, even if they have stocks of sinful activities from many, many births." In other words, a person who is engaged in the worship of the Deities can minimize his stock of sinful reactions coming from many, many previous births. This process of worshiping the Deity has already been described, and one should try to follow these rules and regulations seriously.
In the Liṅga Purāṇa there is a statement about glorifying and singing about the Lord. It is said there: "A brāhmaṇa who is constantly engaged in singing the glories of the Lord is surely elevated to the same planet as the Supreme Personality of Godhead. Lord Kṛṣṇa appreciates this singing even more than the prayers offered by Lord Śiva."
When a person loudly chants the glories of the Lord's activities, qualities, form, etc., it is called saṅkīrtana. Saṅkīrtana also refers to the congregational chanting of the holy name of the Lord.
In the Viṣṇu-dharma there is a statement glorifying this process of congregational chanting: "My dear King, this word 'Kṛṣṇa' is so auspicious that anyone who chants this holy name immediately gets rid of the resultant actions of sinful activities from many, many births." That is a fact. There is the following statement in Caitanya-Caritāmṛta: "A person who chants the holy name of Kṛṣṇa once can counteract the resultant actions of more sinful activities than he is able to perform." A sinful man can perform many, many sinful activities, but he is unable to perform so many that they cannot be wiped out by one single uttering of "Kṛṣṇa."
In the Seventh Canto, 9th Chapter, 17th verse, of Śrīmad-Bhāgavatam, Mahārāj Prahlāda offers the following prayers to the Lord: "My dear Lord Nṛsiṁha, if I can be elevated to the position of Your servant, then it will be possible for me to hear about Your activities. You are the supreme friend, the supreme worshipable Deity. Your pastimes are transcendental, and simply by hearing of them one can counteract all his sinful activities. Therefore, I shall not care for all those sinful activities because simply by hearing about Your pastimes I shall get out of all the contamination of material attachment."
There are many songs about the Lord's activities. For example, there is the Brahma-saṁhitā, sung by Lord Brahmā, Nārada-pañcarātra, sung by Nārada Muni, and Śrīmad-Bhāgavatam, sung by Śukadeva Gosvāmī. If these songs are heard by any person, he can easily get out of the clutches of material contamination. There should be no difficulty in hearing these songs of God. They are coming down from many, many millions of years ago, and people are still taking advantage of them. So why, at this time, should one not take full advantage and thus become liberated?
