You describe that you are seeing more and more how Krishna is your friend and this is very nice. The more one understands that Krishna is my friend and my duty is to serve my Dearest Friend, the more one can know that his is advancing in Krishna Consciousness.
Regarding your question about Supersoul, we take it from Bhagavad-gita philosophy that the distinction between Supersoul and individual jiva soul must always be there. The Supersoul never will fall under the clutches of this illusory maya and the jiva soul has this tendency. So there is distinction, yet, the two, Supersoul and jiva soul are also the same as much as the sunlight and the Sun are qualitatively the same. So this is Krishna's message that we are simultaneously one and different from Krishna. When the jiva soul accepts the dictates of the Supreme consciousness Supersoul, his activities will no longer be for the sake of personal sense gratification but will be only for the purpose of gratifying the senses of Krishna. This attitude of service is the perfection of the living entity.
Please continue to try for the printing of Back To Godhead French edition. We work so that men of all languages and cultures may join us in chanting Hare Krishna and for this we need so many literatures in so many different languages. So please try for this. As you are His sincere servitor Krishna will provide you with the intelligence to do this nicely.
