What we are seeing in this material world? Something material and something spiritual. Material means which has no sense or which has no moving power, and spiritual means which has got sense and which has got moving power. That is the difference between material and spiritual. So if we try to understand simply our body, actually that is meditation. Meditation means to understand what is this body and what I am. If you know these things . . . (break)
Kṣetra means field. Just like a tiller, agriculturist, he is given a certain tract of land, and he tills and produces grains or some vegetables or something eatable. And according to his capacity, there is production, and he makes profit out of it. Similarly, this body is the field, and I am, or you are, who is occupying this body, we are tillers. This body is given by nature, and I am spirit soul. As I want . . . just like one may possess a very valuable land, one may possess not so valuable, ordinary, and one may possess a third-class field, similarly, we living entities, we are given a certain type of body to work with it and enjoy or suffer the resultant action.
We are part and parcel of God. As we are living beings, similarly Kṛṣṇa, or God, is also living being. But He is Supreme; we are subordinate. God is great, and we are under Him. Just like in a family the father is the chief man, and the next important is my mother, and we all children, they are all subordinate to the father and mother. The father earns. The mother distributes. We eat. We live.
