As long as one is absorbed in the bodily conception, his activities are performed on that platform. This is not very difficult to understand. In the world, we see that every nation is trying to supersede every other nation and that every man is trying to advance beyond his fellow man. All these activities are going on under the name of advancement of civilization. There are many plans for making the body comfortable, and these plans are carried in the subtle body after the destruction of the gross body. It is not a fact that after the gross body is destroyed the living entity is finished. Although many great philosophers and teachers in this world are under the impression that after the body is finished everything is finished, this is not a fact. Narada Muni says in this verse that at death one takes his plans with him (grhniyat), and to execute these plans he gets another body. This is called punar bhavah. When the gross body is finished, the plans of the living entity are taken by the mind, and by the grace of the Lord, the living entity gets a chance to give these plans shape in the next life. This is known as the law of karma. As long as the mind is absorbed in the laws of karma, a certain type of body must be accepted in the next life.
