Chanting: Chanting Pancha-tattva Mantra

                                                                  Q. What is the proper method to chant the Hare Krishna mantra? If someone is chanting 16 rounds, then should one chant the Panca-tattva mantra after every round or should we chant the Panca-tattva mantra at the beginning of chanting & then continuously chant the Hare Krishna mantra without break?

                                                                  Did Srila Prabhupada introduce the chanting of Panca-tattva mantra after every round? Please enlighten me on this.
