If Western people are expert in technological knowledge, and if their natural tendency is to develop it, let them do it. But as far as we Indians are concerned, our people are naturally inclined for spiritual elevation. Therefore, even in these days also when there is Kumbha Mela at Prayag or any other place, or there is a particular function in some pilgrimage like Jagannatha Puri, Vrindaban, Haridwar, etc., millions of people gather without any advertising. So these natural tendencies should not be disturbed, but the people of a particular section of the world should develop their indigenous talent and then exchange with others. So the Western people may give us their product, and we may give them our product; and by such exchanging policy, both of us may flourish in our civilized way of life.
Unfortunately, in India, at the present moment, our blind leaders are completely neglecting development of our indigenous talent. Therefore, India is in a position of misadjustment. I have got practical experience that some of the Indian students in this country directly criticize this Krishna Consciousness Movement; so I am very glad that you are giving some serious attention to this Movement, and I wish may Krishna bless you for your further advancement.
Now coming to the point of questions—your first question is: "What am I? Is the body itself matter, or spiritual soul, or a combination of both?" Answer: You are eternal servant of Krishna. The body is matter. The spirit soul is different from the body—it is not exactly combination, but it is encagement. Just like if you put oil in the water, the oil does not mix up with the water. Similarly, soul does not mix with the material body; but due to our material consciousness, we are thinking that the movement of this body is movement of the soul. Therefore, when the body is destroyed, we think the soul is destroyed. That is stated in the Bhagavad-gita, that the soul does not die with the destruction of the body. With the destruction of one body, the soul transmigrates to another body, thus the bondage of material existence. Therefore, to train the soul properly to revive his original consciousness, or Krishna Consciousness, is the real purpose of human life.
