Arjuna said: O my dear Kṛṣṇa, I wish to know about prakṛti [nature], puruṣa [the enjoyer], and the field and the knower of the field, and of knowledge and the object of knowledge.

The Supreme Personality of Godhead said: This body, O son of Kuntī, is called the field, and one who knows this body is called the knower of the field.
