In the Siva Purana, the name is mentioned with the syllables. Lord Siva said these two syllables ‘Krish’…’Na’.. these are the reservoir of all pleasure. The all attractive form of the Lord. These two syllables, are param brahma, and they are equal to 3000 times chanting the name of Vishnu, the sahasra-naam of Vishnu.
If you chant 3 times… or if you chant Hare Krishna once… the one name of Krishna has the same effect…That these names are specifically given… There are so many names given, and by chanting those specific vibrations, one gets delivered.
In the Srimad Bhagvatam, it says even if one circumstantially says that vibration he gets delivered. Accidentally if someone says that vibration…
There was one devotee of Lord Caitanya, he would regularly go to one Muslim magistrate and request him to chant “Hare Krishna”. But he would always avoid. but one day he said, “Alright, alright…Tomorrow I will chant Hare Krishna”. Hariiii Booool…..Hariiii Booool…..Hariiii Booool….Hariiii Booool…. “You have already chanted..you have already said the name of Krishna..you’ve begun..now dont stop.go on chanting..you have already delivered by accidentally chanting it. So go on chanting Hare Krishna…Hare Krishna…Krishna Krishna…Hare Hare…Hare Rama…Hare Rama…Rama Rama…Hare Hare…”
