Kṣetra, kṣetra means field, and jñāḥ, jñāḥ means knower. Kṣetrajñāḥ. So you are knower of the field of your existence.
So if you study yourself, that "I am spirit soul and this body is external expansion only," then you can understand that within this external expansion of cosmic manifestation there is the Supersoul. This is confirmed in the Bhagavad-gītā: viṣṭabhyāham idaṁ kṛtsnam ekāṁśena sthito jagat (BG 10.42). The Lord says that "By My one portion I enter into this cosmic manifestation and thus I maintain it." Similarly, as we are maintaining this body by entering into this body, similarly God is maintaining this cosmic manifestation by entering into it. Therefore we are qualitatively one. As I enter into this material body and expand it and maintain it, similarly the Supersoul enters into this cosmic manifestation and maintains it and develops it. (disturbance in the background) (aside:) That's all right. Don't disturb. So as you have got consciousness, a small consciousness or limited consciousness, similarly the Supersoul has got unlimited consciousness. You are conscious of your bodily existence, I am conscious of my bodily existence, but I am not conscious of your bodily existence, neither you are conscious of my bodily existence. That is also explained in the Bhagavad-gītā. And the Supersoul is conscious of your bodily existence and my bodily existence. Therefore God is present everywhere—in your heart, in my heart, in everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). It is specifically mentioned that Supersoul is everywhere within the heart of every living entity. The exact Sanskrit word used in this connection is called kṣetrajñāḥ. (to translator:) Yes, explain. Kṣetra, kṣetra means field, and jñāḥ, jñāḥ means knower. Kṣetrajñāḥ. So you are knower of the field of your existence. That means this body. The body is the field of your existence. Just like a cultivator has got a tract of land, a small land which he cultivates in his own way, similarly, we have got this small body and we are called kṣetrajñāḥ, knower of this body. Just like if you study each and every part of your body, you will understand that "It is mine." You will claim this finger as your finger, but you'll not claim other's finger as your finger. But God can claim your finger and my finger as His finger. Kṣetra-jñāṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata. It is said, "My dear Arjuna, as individual soul is the proprietor of that individual body, I am also proprietor not of that individual body but all bodies." Everything.
