Krishna Consciousness: Transcendental Realizations

                                                                  Q. Going through a discussion on Bhagavad-Gita, we discussed regarding "Why Krishna had to start a new parampara?" During the discussion we encountered many complex understandings.
                                                                  Krishna says in beginning of Bhagavad-Gita Chapter 4, He chose Arjuna as the first one to get the knowledge of Bhagavad-Gita for the new parampara. Now our concerns are:

                                                                  Q. Is it limiting, on an absolute level, when one claims an exclusive name/form as being the highest realization of Godhead? In other words, once someone says the highest can only be this, it seems to impart a restriction on God based on the condition of the particular consciousness (of that individual).

                                                                  Q. The sixth chapter of the Bhagavad Gita says that one who has conquered his mind has reached the Supersoul.  This chapter is told in the context of laying out dhyana yoga.  But, we practice bhakti-yoga.  Does a pure and realized devotee of Krishna (here, I mean the devotee has conquered the mind, too) see Krishna in everyone's heart or the Supersoul?  If the answer is "Krishna," does he in any circumstances see the Supersoul?
