Hari-śauri: Purport. "While discussing the subject of this body and the owner of the body, the soul and the Supersoul, we shall find three different topics of study: the Lord, the living entity, and matter. In every field of activities, in every body, there are two souls: the individual soul and the Supersoul. Because the Supersoul is the plenary expansion of the Supreme Personality of Godhead, Kṛṣṇa, Kṛṣṇa says, 'I am also the knower, but I am not the individual owner of the body. I am the superknower. I am present in every body as the Paramātmā, or Supersoul.' One who studies the subject matter of the field of activity and the knower of the field very minutely, in terms of this Bhagavad-gītā, can attain to knowledge. The Lord says: 'I am the knower of the field of activities in every individual body.' The individual may be the knower of his own body, but he is not in knowledge of other bodies. The Supreme Personality of Godhead, who is present as the Supersoul in all bodies, knows everything about all bodies. He knows all the different bodies of all the various species of life. A citizen may know everything about his patch of land, but the king knows not only his palace but all the properties possessed by the individual citizens. Similarly, one may be the proprietor of the body individually, but the Supreme Lord is the proprietor of all bodies. The king is the original proprietor of the kingdom, and the citizen is the secondary proprietor. Similarly, the Supreme Lord is the supreme proprietor of all bodies. The body consists of senses. The Supreme Lord is Hṛṣīkeśa, which means controller of the senses. He is the original controller of the senses, just as the king is the original controller of all the activities of the state, and the citizens are secondary controllers. The Lord also says, 'I am also the knower.' This means that He is the superknower; the individual soul knows only his particular body. In the Vedic literature, it is also stated..."
Prabhupāda: Just like pains and pleasure. You know your bodily pains and pleasure, I know my body. But I do not know your bodily pains, neither you know mine. But God knows everyone's pains and pleasures. That is the difference between God and individual soul.
