and consequently One Creator. Hence he serves G-d even while engaged in the unavoidable material aspects of life, and does so with joy, inasmuch as it is in them and through them that he recognizes the greatness of the Creator and they help strengthen his unity with G-d.
Thus we have two ways in the service of G-d, of which the first is the easier one, while the second leads to a better fulfillment of the objective - to make this lowest physical world an abode for G-d.
3) An observation of my own
It seems a novel way of trying to learn Chassidus by correspondence. Even where there is no other choice, it is difficult to cover such a subject in the course of a letter. But in your case, you are within personal reach of receiving oral and fuller explanations, in the normal course of study under the teachers of Chassidus in Tomche Tmimim and with the aid of the senior students who have been learning Chassidus for years. Why not use this better method?
With all good wishes,
