One reflection on the question:
The mind is considered the 6 senses. We actually enjoy the mind much more than with other senses. The mind has so many different impressions from our material life and he doesn't have or doesn't remember the bliss from spiritual activities performed purely. When we with faith and determination from our association and taking the wisdom of these lectures seriously, start practicing chanting meditation, we will soon enough have many internal realizations that will attach the mind to chanting. So, experiencing higher internal pleasure
Hope it helps!
