Chanting mahamantra is completely authorised process. It’s not that only Lord Caitanya Mahaprabhu presented this process Five hundred years ago. We find here that five thousand years ago in the Bhagavatam Sukadeva Goswami also is confirming the process, saying that the constant chanting of the holy name of the Lord is a doubtless and fearless way of success for all. You see, whether one is free from all material desires, whether one desires all material enjoyment, or whether one is self-satisfied, a yogi. Either for the devotees, for the materialists or for the yogis, chanting Hare Krishna is a perfect process recommended for all. So to get the maximum effect, it advises us here… the Bhagavatam has advised us here that we should avoid all the offences.
