How does one get off the platform from nāma-aparādha to nāmaābhāsa, and gradually come to the platform of śuddha-nāma? He has to chant with the attitude of “what is the goal of this chanting?!” Even though he may be committing offences while chanting, he has to be thinking, “I want to become free from these offences!” That attitude enables one to make progress in chanting of the Holy Name of the Lord. Just that attitude alone!
