karsati, or struggle for existence

Here the living entity is described as isvara, the controller of his own body. If he likes, he can change his body to a higher grade, and if he likes he can move to a lower class. Minute independence is there. The change his body undergoes depends upon him. At the time of death, the consciousness he has created will carry him on to the next type of body. If he has made his consciousness like that of a cat or dog, he is sure to change to a cat's or dog's body. And if he has fixed his consciousness on godly qualities, he will change into the form of a demigod. And if he is in Krsna consciousness, he will be transferred to Krsnaloka in the spiritual world and will associate with Krsna. It is a false claim that after the annihilation of this body everything is finished. The individual soul is transmigrating from one body to another, and his present body and present activities are the background of his next body. One gets a different body according to karma, and he has to quit this body in due course. It is stated here that the subtle body, which carries the conception of the next body, develops another body in the next life. This process of transmigrating from one body to another and struggling while in the body is called karsati, or struggle for existence.

Living Entity and Lord

As fragmental parts and parcels of the Supreme Lord, the living entities also have fragmental portions of His qualities, of which independence is one. Every living entity, as an individual soul, has his personal individuality and a minute form of independence. By misuse of that independence one becomes a conditioned soul, and by proper use of independence he is always liberated. In either case, he is qualitatively eternal, as the Supreme Lord is. In his liberated state he is freed from this material condition, and he is under the engagement of transcendental service unto the Lord; in his conditioned life he is dominated by the material modes of nature, and he forgets the transcendental loving service of the Lord. As a result, he has to struggle very hard to maintain his existence in the material world.
