The Yoga of the Imperishable Brahman. Chapter 8 is the Gīta's eschatological chapter — the teaching on what happens at death and after. Eight technical terms are defined, Oṃ is designated the syllable of Brahman, BG 8.7 commands "remember Me and fight," and the two cosmic paths after death — devayāna and pitṛyāna — are mapped.

Chapter Summary
Arjuna opens Chapter 8 with seven consecutive questions: what is Brahman? What is Adhyātma? What is Karma? What is Adhibhūta? What is Adhidaiva? What is Adhiyajña — and how is one to know it at the time of death? Kṛṣṇa provides technical definitions for each, then teaches the supreme importance of the mental state at the moment of death: whatever one thinks of at the time of death, to that one goes. The chapter then presents the two cosmic paths — the bright path (devayāna) leading to liberation and the dark path (pitṛyāna) leading to rebirth.
Name:Akṣara-brahma-yoga — the yoga of the imperishable Brahman. Akṣara = imperishable (from a = not + kṣara = that which perishes/flows). The chapter centres on the teaching about what is truly akṣara — imperishable — and how to reach it.
Chapter 8 answers Arjuna's seven technical questions about the nature of ultimate reality, then teaches the supreme practical truth: the last thought at death determines the next destination — so cultivate constant remembrance of Kṛṣṇa now.
The eight technical terms — BG 8.1–8.4
Arjuna's opening questions are among the most concisely phrased in the Gīta. In two verses (8.1–8.2) he asks seven questions, covering the full spectrum of cosmological and soteriological reality. Kṛṣṇa answers in three verses (8.3–8.4):
Brahman
8.3a
The imperishable, the supreme. Akṣaraṃ brahma paramaṃ — the highest, indestructible Brahman. The absolute ground of all existence.
Adhyātma
8.3b
The self-nature or own-being. Svabhāvo 'dhyātmam ucyate — that which pertains to the individual self; the self's own nature; the individual Ātman or self as the domain of Brahman in the individual.
Karma
8.3c
Offering, creative action. Visarga-karma-saṃjñitaḥ — the creative impulse or offering that brings beings into existence; the action that is the productive cause of beings.
Adhibhūta
8.4a
The perishable, material domain. Kṣaro bhāvaḥ — the perishable entity; all the mutable, transient, physical existence that constitutes the material world.
Adhidaiva
8.4b
The divine domain — the cosmic Person. Puruṣaś cādhidaivatam — the cosmic Puruṣa (the divine being that presides over the cosmic process); the divine aspect of existence.
Adhiyajña
8.4c
The domain of sacrifice. Aham evādhiyajño 'tra dehe — "I am the Adhiyajña here in the body." Kṛṣṇa himself is the divine aspect of sacrifice present within the body of every being. This answer is the most theologically striking of the six.
BG 8.1–8.4. Gambhirananda (trans.), pp. 360–370.
BG 8.7 — remember Me and fight
BG 8.7 — The practical instruction
तस्मात्सर्वेषु कालेषु मामनुस्मर युध्य च
tasmāt sarveṣu kāleṣu mām anusmara yudhya ca
"Therefore at all times, remember Me — and fight."
मय्यर्पितमनोबुद्धिर्मामेवैष्यस्यसंशयम्
mayy arpita-mano-buddhir mām evaiṣyasy asaṃśayam
"With mind and intellect surrendered to Me, you will come to Me alone — there is no doubt."
This verse draws together the entire Karma Yoga and devotion teaching: act fully (yudhya ca — fight!) and simultaneously keep the mind on Kṛṣṇa. The mental orientation at every moment — not only at death — determines the trajectory. "Surrendering mind and intellect to Me" = the Bhakti Yoga attitude that makes action into worship. The guarantee: "you will come to Me alone — without doubt."
The two cosmic paths — BG 8.24–8.26
Devayāna
The path of the gods · the bright path
Fire, light, day, the bright fortnight, the six months of the northern course of the sun — those who know Brahman, following this path, go to Brahman.
No return — liberation (Mokṣa). The one who takes this path does not return to saṃsāric rebirth.
Pitṛyāna
The path of the ancestors · the dark path
Smoke, night, the dark fortnight, the six months of the southern course of the sun — the yogī who attains these goes to the lunar world and returns.
Return — rebirth. The one who takes this path enjoys the heavenly realm and then returns to be born again.
BG 8.24–8.26. Gambhirananda (trans.), pp. 395–403. This teaching parallels the Pañcāgni Vidyā of the Chāndogya Upaniṣad (5.3–5.10) — the two paths of the dead are a teaching shared between the BG and the Upaniṣadic tradition.
The chapter's most striking teaching — and the one that motivates BG 8.7 — is about the determinative power of the final thought at death: "Whoever at the time of death remembers Me alone, having given up the body, reaches my state. There is no doubt about this." (BG 8.5) And the general principle (BG 8.6): yaṃ yaṃ vāpi smaran bhāvaṃ tyajaty ante kalevaram / taṃ tam evaiti kaunteya sadā tad-bhāva-bhāvitaḥ — "Whatever state of being one remembers when giving up the body at the end — to that state of being one goes, O Kaunteya, always made to be of that nature." The final thought is not random — it is the distilled expression of the entire mental habit-pattern of a lifetime. What one has cultivated throughout life will naturally predominate at death. Hence the instruction: cultivate it now.
BG 8.5–8.6. Gambhirananda (trans.), pp. 371–378.
BG 8.13 — the syllable Oṃ
BG 8.13 — Oṃ as the syllable of Brahman
ओमित्येकाक्षरं ब्रह्म व्याहरन्मामनुस्मरन्
oṃ ity ekākṣaraṃ brahma vyāharan mām anusmaran
"Pronouncing the single syllable Oṃ — which is Brahman — and remembering Me —"
यः प्रयाति त्यजन्देहं स याति परमां गतिम्
yaḥ prayāti tyajan dehaṃ sa yāti paramāṃ gatim
"— one who departs giving up the body thus goes to the supreme goal."
Oṃ is the syllable of Brahman — the Māṇḍūkya Upaniṣad's teaching appears here in a devotional context. The practice: at the moment of death, while holding the prāṇa (life-force) between the eyebrows (as described in BG 8.10), one utters Oṃ and keeps the mind on Kṛṣṇa. This is the highest practice at death — the distillation of a lifetime's spiritual cultivation into a single syllable and a single remembrance.
Parallel with the Chāndogya Upaniṣad — the Pañcāgni Vidyā
The two-paths teaching of BG 8.24–8.26 (devayāna vs pitṛyāna) is closely parallel to the Pañcāgni Vidyā (five-fires teaching) of Chāndogya Upaniṣad 5.3–5.10. The Upaniṣadic version describes how the dead travel through fire/rain/food to be born again (pitṛyāna) or how the liberated travel through fire/day/light/sun to reach Brahman (devayāna). This Upaniṣadic teaching forms the cosmological background for the BG's eschatological teaching. Both sources present the two paths as determined by the quality of knowledge and practice in the previous life.
Arjuna's opening questions in BG 8.1–8.2 are a model of philosophical precision. In two verses he asks seven questions that span the entire range of cosmological and soteriological reality. Uniquely, he asks the seventh question — about Adhiyajña and how it is known at the time of death — in the same breath as the cosmological questions. This connects the metaphysical (what is the ultimate structure of reality?) directly to the practical (how does one realise this at the final moment?). Chapter 8 answers all seven but spends most of its teaching on the practical answer to the seventh question.
Śaṅkara on the Akṣara Brahman and the two paths
Śaṅkara reads BG 8.3 (akṣaraṃ brahma paramaṃ) as referring to the absolute, nirguṇa Brahman — the imperishable ground of all existence. The chapter title thus refers to the highest: the yoga of reaching the imperishable Brahman. The two paths (BG 8.24–8.26) are, in Śaṅkara's reading, relevant primarily to those who have not yet attained direct knowledge of Brahman: those who have practised Upāsanā (meditation on Saguna Brahman) but not Jñāna take the bright path (devayāna) and attain Brahmaloka, then Mokṣa; those who have accumulated merit but not knowledge take the dark path (pitṛyāna), enjoy the lunar world, and return. The fully liberated Jñānī goes directly beyond both paths.
