The Lord said: This body, Ο son of Kunti, is called the Field, and he who knows it is called the Knower of the Field by those who describe them.
‘Kshetram‘ means field. The field is necessary for growing corn and other things to sustain the beings of the world. So also the body is necessary for the growth of the seed of knowledge in the heart of man. All ‘sadhana’, ‘tapas’, thinking and meditation – all this is to be done with the body. So the body, the ‘kshetra’, is the field for the growth of the, seed of ‘Dharma’ as well as ‘Jnana’. Therefore it is called ‘kshetra’.
The body being inert (Jada’) does not know itself; There is a consciousness within with power to cognise the body. This consciousness power is known as ‘kshetrajna.’ He is ‘Pratyagatma’. He is the witness of the combined elements of the body, senses and the mind. He is changeless, pure, intelligence, deathless, separate from the five sheaths (Panchakosas). What is inert cannot know itself. The wall does not know that it is a wall, nor does a pot know that it is a pot. It is intelligence that has the power of cognition. That Intelligence is the Knower of the body. He knows. He (‘kshetrajna‘) is pure Intelligence.
The knower of the field is certainly different from the field. So the knower of the body should certainly be distinct from the body. Though Intelligence is in the body, yet it remains free and perfect, witnessing the modifications of the body and mind during all the three states of wakefulness ‘Jagrat’, dream ‘Svapna’ and sleep ‘Sushupti’.
