Lord Krishna explains the distinction between the Kshetra (the Field, or the physical body and the material world) and the Kshetragna (the Knower of the Field, or the soul). He describes the body as a temporary vessel and the soul as the eternal observer within it. Krishna reveals that he is the supreme Knower present in all fields, emphasizing the unity of the divine with all beings. He explains the nature of material existence, the elements of creation, and the characteristics of wisdom. By understanding the difference between the body and the soul, and recognizing the soul's eternal connection to the divine, one can achieve true knowledge and ultimately liberation. This chapter emphasizes self-awareness, detachment, and the pursuit of knowledge as keys to spiritual growth.
