The Kṣetra and the Kṣetrajña
Kṣetra — the Field
Everything that is experienced: the five great elements, ego, intellect, the unmanifest (avyakta), the ten senses, the one mind, the five sense objects, desire, aversion, pleasure, pain, the aggregate, intelligence, and fortitude. The body-mind-Prakṛti complex in its totality — everything that can be an object of awareness.
Kṣetrajña — the Knower
The pure witnessing consciousness — the Ātman — that knows the Field. It is never itself an object; it is always the subject. Kṛṣṇa identifies himself with the Kṣetrajña in all Kṣetras: "Know Me to be the Kṣetrajña in all the Fields" (BG 13.2). The same witnessing consciousness is present in every body as the inner knower.

The twenty qualities of knowledge — BG 13.7–13.11
Chapter 13 contains the Gīta's most detailed positive definition of jñānam (knowledge, in the sense of liberating wisdom). These are not epistemological characteristics but ethical-spiritual qualities that constitute the inner environment in which true knowledge arises:
Twenty qualities of jñāna — BG 13.7–13.11 (Gambhirananda trans.)
- Amānitvam — absence of pride
- Adambhitvam — absence of pretension/deceit
- Ahiṃsā — non-injury
- Kṣāntiḥ — patience, forbearance
- Ārjavam — uprightness, sincerity
- Ācāryopāsanam — service to the teacher
- Śaucam — purity (internal and external)
- Sthairyam — steadiness
- Ātma-vinigrahaḥ — self-restraint
- Indriyārtheṣu vairāgyam — dispassion toward sense objects
- Anahaṅkāraḥ — absence of ego-sense
- Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam — perceiving the evil in birth, death, old age, disease, and sorrow
- Asaktir anabhiṣvaṅgaḥ — non-attachment, non-clinging
- Sama-cittatvam — equanimity in all situations
- Mayi cānanya-yogena bhaktir avyabhicāriṇī — unswerving devotion to Me through Yoga of non-otherness
- Vivikta-deśa-sevitvam — fondness for solitary places
- Aratir jana-saṃsadi — absence of delight in the company of people
- Adhyātma-jñāna-nityatvam — constancy in self-knowledge
- Tattva-jñānārtha-darśanam — perception of the purpose of the knowledge of truth
- Etaj jñānam — "this is knowledge; what is contrary to this is ignorance"
The Knowable — BG 13.12–13.18
After defining the Kṣetra, the Kṣetrajña, and the twenty qualities of knowledge, Kṛṣṇa turns to the jñeyam — the Knowable — that which, when known, leads to liberation (BG 13.12). The Knowable is Brahman: "anādi mat-param brahma na sat tan nāsad ucyate" — "The beginningless supreme Brahman is said to be neither existent nor non-existent" (BG 13.12). This apophatic definition echoes the Upaniṣadic tradition (the Nāsadīya Sūkta, the Māṇḍūkya Upaniṣad's description of Brahman as beyond sat and asat).
BG 13.13–13.17 describes the Knowable: it has hands and feet everywhere; eyes, heads, faces everywhere; ears everywhere; it stands pervading everything in the world. It seems to have sense functions yet is beyond all senses; unattached, yet sustaining all; without Guṇas, yet experiencing the Guṇas; inside and outside beings; moving and unmoving; far yet near; undivided yet appearing divided in beings; it is the sustainer of beings; the devourer; and the originator.
BG 13.12–13.18. Gambhirananda (trans.), pp. 566–576.
BG 13.27–13.28 — seeing the same Lord in all
BG 13.33 — the sun and the single light
Śaṅkara on the Kṣetra-Kṣetrajña teaching
Śaṅkara's Gītābhāṣya treats Chapter 13 as the clearest statement in the Gīta of the fundamental Advaita thesis: the identity of the individual Ātman (Kṣetrajña in a particular Field) with the supreme Brahman (the Kṣetrajña in all Fields). When Kṛṣṇa says "Know Me to be the Kṣetrajña in all Fields" (BG 13.2), Śaṅkara reads this as the identification of the individual witnessing consciousness with the supreme consciousness — the same identity that the Mahāvākyas (Ahaṃ Brahmāsmi, Tat Tvam Asi) express. The twenty qualities of knowledge (BG 13.7–13.11) are not the knowledge itself but the conditions that make the recognition of this identity possible.
BG 13.2; 13.7–13.11; 13.33. Śaṅkara, Gītābhāṣya (Gambhirananda trans.), pp. 554–556; 563–571; 591–593.
