Chanting: Stages of Chanting

                                                                  Q. What are the different stages of chanting? How can one understand that one's chanting is good and pure? Is there any unit to measure the purity of the chanting?

                                                                  Q. Can you kindly explain what are the potential realizations in each stage of chanting i.e. nama-aparadha, nama-abhasa, and suddha-nama? Is there any positive realization (that which is favorable to Krishna consciousness) for a person in nama-aparadha stage? In other words, how can one know that one is progressing from one stage to another?

                                                                  Q. I love chanting. It makes me feel wonderful. When I'm chanting I am thinking about Krishna, and many times I  remember some pastimes of Krishna when I chant His name. To give an example, when I chant in front of a lake at the park I usually visualize Krishna in a boat with the gopis, just like the wonderful painting of this lila. One devotee then said it was wrong, because I was deviating from the Holy Name. What about that? Isn't the Holy name and Krishna the same? What's wrong if I remember Krishna one way or another when I'm chanting?

                                                                  Q. In the Bhagavad-Gita, last verse of the second chapter, Krishna says that "... If one is thus situated even at the hour of death, one can enter into the kingdom of God". Also the purpose of all the practice that we do is to remember Krishna at the time of our final exam - The DEATH. Regarding Ajamila's deliverance, is his previous karma also involved in this or is it just purely because he chanted Krishna's name?
