This śarīra, this body, is called kṣetra, and the person, or the living entity, who is working on this body, he is called kṣetra-jña. Those who have read Bhagavad-gītā, they have come to this understanding of kṣetra and kṣetra-jña. Ksetre-jña means I, you. I know about my body, about the interest of my body. If somebody wants to kill me, I take protection because it is my body, kṣetra. Just like your land, if somebody comes to encroach upon it, you take care. Similarly, this body is kṣetra, the field of activities, and I or you, the proprietor of the body, is kṣetra-jña, one who knows about the body.
But there is another kṣetra-jña. That is Kṛṣṇa. That is explained in the Bhagavad-gītā: ksetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata. Sarva-kṣetreṣu. Kṛṣṇa is also kṣetra-jña, Kṛṣṇa is also sitting . . . as I am sitting within this body, similarly, Kṛṣṇa is also sitting within this body.

He is directing. Actually, under His instruction we are taking permission. Just like you do business in your business office, establishment, but you have to take permission, license, from the government. It is very easy to understand. Although you are proprietor of the business, you cannot do anything without being permitted by the government. Similarly, although this body is yours—you are the proprietor of this body, you have been given freedom to utilize the body to your best interest—still, you cannot do anything without the permission of Kṛṣṇa.
