Explanation
Krishna is explaining what the "field" (kṣetra), meaning the body and the nature it is made of, consists of, and he lists its parts in the manner of Sāṃkhya. They are the five great elements (mahābhūta), the sense of "I" (ahaṅkāra), the intellect (buddhi), the unmanifest source of nature (avyakta), the ten senses (five of knowing and five of action), the mind, and the five sense objects (sound, touch, form, taste, smell). Commentators differ on what the unmanifest is: some take it as primal nature (prakṛti), others as the seed-like causal power from which the world unfolds. The sentence continues into the next verse.
