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.
