- prakṛtiṁ puruṣaṁ caiva
- kṣetraṁ kṣetra-jñam eva ca
- etad veditum icchāmi
- jñānaṁ jñeyaṁ ca keśava
Kṛṣṇa's another name is Keśava. So he is addressing Kṛṣṇa, "My dear Keśava, I want to know these subject matters—prakṛti, puruṣa." Prakṛti means nature, material nature, and puruṣa means the enjoyer, just like the living entities. We are trying to enjoy this material nature. Another prakṛti-puruṣa... Puruṣa means, real puruṣa means, the supreme enjoyer, God, Kṛṣṇa. And prakṛti means which is enjoyed. Another meaning—prakṛti, means woman and puruṣa means man. So this material world is going on—one party is trying to enjoy, and the other party is being enjoyed.
So Arjuna wanted to know what is the distinction, what is the integral part and parcel of this prakṛti and puruṣa. Then kṣetraṁ kṣetra-jña. Jña means one who knows, and kṣetra-jña means one who knows the field. Just like the agriculturist, the cultivator, he knows that "This is my field." He works there. Different cultivator works in his own field. So this kṣetra means this body, kṣetra, the field of activity. We have got different field of activities. So kṣetraṁ kṣetra-jñaṁ ca, kṣetram eva etad veditum icchāmi: "My dear Kṛṣṇa, I want to know from You." Why he wants to know from Kṛṣṇa? Because Kṛṣṇa is infallible. Whatever knowledge we get from the infallible, that is perfect knowledge.
