You have been given the holy name. There are many details which must be given for cultivating the quality of chanting and for progressing through the different stages of chanting. Those details are gradually being given as well. But why are the instructions on chanting more important than the details of one's specific relationship with Krishna? Because through chanting Krishna's holy names, all of these details are revealed by the holy name Himself. It is true that previously there was more emphasis on these details given by the spiritual master, but due to extensive abuse of this method by unqualified gurus and followers, Srila Bhaktivinode Thakur, and in his line, Srila Bhaktisiddhanta Sarasvati Thakur and Srila Prabhupada, have all placed far greater stress on the importance of offenseless chanting.
