One who chants the holy name of the Lord is immediately freed from the reactions of unlimited sins, even if he chants indirectly to indicate something else (sanketya), jokingly (parihasya), for musical entertainment (stobha), or even neglectfully (helana). This is accepted by all the learned scholars of the scriptures. SB 6.2.14

As a fire burns dry grass to ashes, so the holy name of the Lord, whether chanted knowingly or unknowingly, burns to ashes, without fail, all the reactions of one’s sinful activities. SB 6.2.18

Devotional service, beginning with the chanting of the holy name of the Lord, is the ultimate religious principle for the living entity in human society.  SB 6.3.22

O King, constant chanting of the holy name of the Lord after the ways of the great authorities is the doubtless and fearless way of success for all, including those who are free from all material desires, those who are desirous of all material enjoyment, and also those who are self-satisfied by dint of transcendental knowledge. SB 2.1.11

There may be discrepancies in pronouncing the mantras and observing the regulative principles, and, moreover, there may be discrepancies in regard to time, place, person and paraphernalia. But when Your Lordship’s holy name is chanted, everything becomes faultless. SB 8.23.16

My dear King, although Kali-yuga is an ocean of faults, there is still one good quality about this age: Simply by chanting the Hare Krishna mahä-mantra, one can become free from material bondage and be promoted to the transcendental kingdom. SB 12.3.51

Whatever result was obtained in Satya-yuga by meditating on Vishnu, in Treta-yuga by performing sacrifices, and in Dväpara-yuga by serving the Lord’s lotus feet can be obtained in Kali-yuga simply by chanting the Hare Krishna maha-mantra. SB 12.3.52

“I am not in Vaikuntha nor in the hearts of the yogés. I remain where My devotees engage in glorifying My activities.” It is to be understood that the Supreme Personality of Godhead does not leave the company of His devotees. Padma Purana

“The chanting of Hare Krishna is recommended for persons who commit offenses, because if they continue chanting they will gradually chant offenselessly. Even if in the beginning one chants the Hare Krishna mantra with offenses, one will become free from such offenses by chanting again and again”

(Padyavali 4)

“One who chants Krishna’s name and constantly remembers Him, even though living in this material ocean of nescience, is like the lotus, which is born in the water but is untouched by it: it’s position is transcendental. This great soul is capable of liberating all the suffering residents of the hellish planets. (Varäha Puräna)

The holy name of Lord Krishna is a reservoir of all transcendental happiness. It destroys the sins of the Kali-yuga. It is the most purifying of all purifying things. It is the saintly person’s food as he traverses the path to the spiritual world. It is the pleasure garden where the voices of the greatest saints, philosophers, and poets play. It is the life of the righteous and the seed of the tree of religion. May that holy name of Lord Krishna bring transcendental auspiciousness to you all.—author unknown (Padyavali 3)

Sri-KRSNA nama is the sweetest among all things that are sweet, and it stands supreme amongst all that is auspicious.It is the eternal, fully ripened spiritual fruit of the wish fulfilling tree of the Vedas. O best of the Bhrgus, if anyone even once offenselessly chants Sri-KRSNA nama, either with faith or indifference, Sri-KRSNA nama immediately delivers that person from the ocean of material existence.

Glorification of the Supreme Personality of Godhead is performed in the paramparä system; that is, it is conveyed from spiritual master to disciple. Such glorification is relished by those no longer interested in the false, temporary glorification of this cosmic manifestation. Descriptions of the Lord are the right medicine for the conditioned soul undergoing repeated birth and death. Therefore, who will cease hearing such glorification of the Lord except a butcher or one who is killing his own self? SB 10.1.4
