The sublime form of religious performances to free oneself from all reactions of sins is suggested herein by the greatest authority, Śrī Śukadeva Gosvāmī. Kīrtanam, or glorifying the Lord, can be performed in very many ways, such as remembering, visiting temples to see the Deity, offering prayers in front of the Lord, and hearing recitations of glorification of the Lord as they are mentioned in the Śrīmad-Bhāgavatam or in the Bhagavad-gītā. Kīrtanam can be performed both by singing the glories of the Lord in accompaniment with melodious music and by recitation of scriptures like Śrīmad-Bhāgavatam or Bhagavad-gītā. The devotees need not be disappointed in the physical absence of the Lord, though they may think of not being associated with Him. The devotional process of chanting, hearing, remembering, etc., (either all or some of them, or even one of them) can give us the desired result of associating with the Lord by discharging the transcendental loving service of the Lord in the above manner. Even the very sound of the holy name of Lord Kṛṣṇa or Rāma can at once surcharge the atmosphere spiritually. We must know definitely that the Lord is present wherever such pure transcendental service is performed, and thus the performer of offenseless kīrtanam has positive association with the Lord. Similarly, remembrance and prayers also can give us the desired result if they are properly done under expert guidance. One should not concoct forms of devotional service. One may worship the form of the Lord in a temple, or one may impersonally offer the Lord devotional prayers in a mosque or a church. One is sure to get free from the reactions of sins provided one is very careful about not committing sins willingly in expectation of getting free from the reactions of sins by worshiping in the temple or by offering prayers in the church.
(Srimad Bhagavatam--------2:4:15-----purport).

"Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear." Thus the Lord takes all responsibility for one who surrenders unto Him, and He indemnifies such a person against all reactions of sins.
mala-nirmocanaṁ puṁsāṁ
jala-snānaṁ dine dine
sakṛd gītāmṛta-snānaṁ
saṁsāra-mala-nāśanam
"One may cleanse himself daily by taking a bath in water, but if one takes a bath even once in the sacred Ganges water of Bhagavad-gītā, for him the dirt of material life is altogether vanquished."
(Bhagavad-Gita--------introduction).

One cannot, however, be engaged in the penance of devotional service without being completely free from all sins. As stated in the Bhagavad-gītā, only a person who is completely free from all reactions of sins can engage himself in the worship of the Lord. Brahmājī was sinless, and therefore he faithfully discharged the advice of the Lord, "tapa tapa," and the Lord, being satisfied with him, awarded him the desired result. Therefore only love and penance combined can please the Lord, and thus one is able to attain His complete mercy. He directs the sinless, and the sinless devotee attains the highest perfection of life.
(Srimad Bhagavatam--------2:9:23-----purport).

The Lord is so kind that He has spread the River Ganges throughout the universe so that by taking bath in that holy river everyone can get release from the reactions of sins, which occur at every step. There are many rivers in the world which are able to evoke one's sense of God consciousness simply by one's bathing in them, and the River Ganges is chief amongst them. In India there are five sacred rivers, but the Ganges is the most sacred. The River Ganges and Bhagavad-gītā are chief sources of transcendental happiness for mankind, and intelligent persons can take shelter of them to go back home, back to Godhead. Even Śrīpāda Śaṅkarācārya recommends that a little knowledge in Bhagavad-gītā and the drinking of a little quantity of Ganges water can save one from the punishment of Yamarāja.
(Srimad Bhagavatam--------3:5:41-----purport).

This kind of admission is very beneficial as long as one does not again commit sin. Cheating and hypocrisy are not tolerated by higher authorities. If one understands what sin is, he should give it up with sincerity and regret and surrender unto the lotus feet of the Supreme Personality of Godhead through His agent, the pure devotee. In this way, one can be freed from the reactions of sin and make progress in devotional service. However, if one continues committing sins after making some atonement, he will not be saved. In the śāstras, such atonement is compared to an elephant’s bathing.
(Sri Caitanya Caritamrta------2:24:253--------purport).
