I feel whenever we are doing bhakti we should do it with full focus and determination . We should call the lord with our heart. Sometimes while chanting we get some various other thoughts and it distracts us of thinking about the lord. How does one really cope up with these distractions so that one gets full benefits from bhakti? Also kindly explain what do you all experience while chanting the mahamantra? I mean what visible results one sees while chanting mahamantra?
