Please don’t think that chanting the Hare Krishna Maha-mantra with offenses will not give any benefit. Still, if we maintain material attachments, our benefit may come in the form of material gain. Such material gain will gradually take us away from our original intention to go to Sri Krishna. If we attach ourselves to material objects, gradually our mind will be engaged in managing material responsibilities and, in the end, the result will be that we will stay far away from Sri Krishna.
