In this sense the living being is the positive energy whereas the matter is the negative energy. The matter does not develop without being in contact with the superior spiritual or anti-material energy which is directly part and parcel of the spirit Whole.
Any way the subject matter of this spiritual energy exhibited by living being is undoubtedly very complicated thing for an ordinary man. The ordinary man is therefore astounded in the subject. Sometimes he partially understands it through the imperfect senses and sometimes he fails to know it altogether. The best thing is therefore to hear the grave subject matter from the highest authority Sri Krishna or His devotee representative coming down in the chain of discipline succession. Bhagwat Geeta is the essence of all the Upanishads and Vedanta.
I am glad to note that you have got the highest estimation for Geeta. I am just trying to present the conclusion of Geeta to the world as it is and without any imperfect compromise with speculative interpretations. We have to learn the lessons of Geeta from the authorised discipline succession as it is advised there in the book (4th Ch.). Unfortunately every one not in that line tries to explain Geeta in his own way and this process misguided the people. We have to counteract this disruptive tendency and put them at right.
I shall be very glad if you join my mission (The League of Devotees) and on receipt of your favourable reply I shall send you the prospectus. An erudite scholar like you should join and help in this noble attempt. Your appreciation of India's cultural heritage is very much enlivening for me. Let us jointly distribute this great cultural heritage to the world at large in an organised manner and through the recommended process of Divine Love propagated by Lord Sri Chaitanya Mahaprabhu.  Please try to help me as far as possible.  Awaiting your reply with interest. Hope you are well.
