The living entity is the Knower of his own body, but Krishna is the Knower of all the bodies

 

The body is called 'kshetra' (field of activity) and the knower of the body, the soul, is called the 'ksetrajna''. As an individual soul I may be the knower of my body. Similarly 'you', as a jivatma, may be the knower of your body. But if you have a headache, unless you tell me I cannot come to know about it. Conversely, if I am thinking of something, you cannot know what I am thinking of. But Krishna, 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. That is why Lord Krishna says in the Bhagavad-gita (13.3)

 

ksetram-jnam capi mam viddhi sarva ksetresu bharata

 

"I am also the knower, but I am not the individual knower of the body. I am the superknower. I am present in every body as the Paramatma, or Supersoul."

 

Just as the individual soul is present by his consciousness throughout the whole body, so the Supersoul (Paramatma) *s present throughout the whole creation by His super- consciousness. This super-consciousness cannot be imitated by the indi­vidual soul, who has limited awareness. I can understand what is going on within my limited body, but I cannot feel what is going on in another's body. I am present all over my body by my con­sciousness, but I am not present in another's body by my con­sciousness. However, the Supersoul, being present within every­one, and being situated everywhere, is conscious of the entire existence.
