Chapter role

The load-bearing chapter of the whole Gītā — Vedānta in miniature. Krishna answers Arjuna's collapse on two levels: (1) metaphysical — the true Self (ātman) is deathless, so grief over killing/dying is misplaced; (2) practical — the discipline of karma-yoga: do your duty without attachment to its fruit. It introduces the sthitaprajña, the sage of "steadfast heart," whose senses are withdrawn "as the wise tortoise draws its four feet."

Atomic statements

G2-C1: The Self is birthless, deathless, and changeless; weapons, fire, water, wind cannot harm it. (FOUNDATIONAL / ATMAN-BRAHMAN)

Gītā 2: "Never the spirit was born; the spirit shall cease to be never; / … Birthless and deathless and changeless remaineth the spirit for ever; / Death hath not touched it at all, dead though the house of it seems!" / "I say to thee weapons reach not the Life; / Flame burns it not, waters cannot o'erwhelm…"
Stance: assert · Importance: core

G2-C2: To think "I slay" or "I am slain" is ignorance — Life cannot slay and is not slain; the embodied soul merely changes bodies as one changes worn-out robes. (FOUNDATIONAL / ATMAN-BRAHMAN+KARMA-SAMSARA)

Gītā 2: "He who shall say, 'Lo! I have slain a man!'… those both / Know naught! Life cannot slay. Life is not slain!" / "as when one layeth / His worn-out robes away, / And taking new ones… / So putteth by the spirit / Lightly its garb of flesh…"
Stance: assert · Importance: core · Depends on: C1

G2-C3: The wise meet pleasure and pain, heat and cold, with constant calm; "the soul that with a strong and constant calm / Takes sorrow and takes joy indifferently / Lives in the life undying." (FOUNDATIONAL / EQUANIMITY)

Gītā 2: "The soul which is not moved, / The soul that with a strong and constant calm / Takes sorrow and takes joy indifferently, / Lives in the life undying!"
Stance: assert · Importance: core

G2-C4: Do your duty (sva-dharma) for its own sake, not for its fruit: "Let right deeds be / Thy motive, not the fruit which comes from them." This is yoga. (FOUNDATIONAL / YOGA-PATHS+DHARMA)

Gītā 2: "Find full reward / Of doing right in right! Let right deeds be / Thy motive, not the fruit which comes from them. / And live in action!… equability / Is Yog, is piety!"
Stance: assert · Importance: core

G2-C5: Acting without attachment to results frees one from the bondage of works (karma-bandha). (FOUNDATIONAL / KARMA-SAMSARA+MOKSHA)

Gītā 2: "Hear now the deeper teaching of the Yog, / Which holding, understanding, thou shalt burst / Thy Karmabandh, the bondage of wrought deeds."
Stance: assert · Importance: core · Depends on: C4

G2-C6: Those who cling to the letter of ritual scripture, craving heavenly reward, lack fixity of soul; rise above the "three qualities" and the "pairs of opposites." (OPERATIONAL / KNOWLEDGE+DESIRE)

Gītā 2: "Specious, but wrongful deem / The speech of those ill-taught ones who extol / The letter of their Vedas…" / "be free of the 'three qualities,' / Free of the 'pairs of opposites'…"
Stance: deny/qualify · Importance: supporting

G2-C7: The mark of the steadfast sage (sthitaprajña): desires abandoned, content in the Self, senses withdrawn "as the wise tortoise draws its four feet." (OPERATIONAL / EQUANIMITY+DESIRE)

Gītā 2: "When one… Abandoning desires which shake the mind— / Finds in his soul full comfort for his soul, / He hath attained the Yog…" / "He who shall draw / As the wise tortoise draws its four feet safe / Under its shield, his five frail senses back…"
Stance: assert · Importance: core

G2-C8: Desire is a chain reaction: brooding on objects breeds attraction → desire → passion → recklessness → ruin of mind and man. The governed mind, holding senses in check, attains peace. (FOUNDATIONAL / DESIRE)

Gītā 2: "If one / Ponders on objects of the sense, there springs / Attraction; from attraction grows desire, / Desire flames to fierce passion… / Till purpose, mind, and man are all undone."

Step 4 — Clusters

Cluster	Atomic statements	Intent
The deathless Self	C1, C2	Metaphysical ground: grief over death is ignorance of the ātman
Equanimity	C3, C7	The fruit of knowledge is a steady, unshaken mind
Karma-yoga	C4, C5	Act for duty, not reward; this frees from bondage
Desire as the danger	C6, C8	Attachment and ritual-craving derail the mind

Step 5 — Internal tensions

Apparent tension: "act!" (C4) vs "abandon desire" (C7). Resolved by the chapter itself — one acts without desire for the fruit; renunciation is of attachment, not of action. (This is the seed of Ch.3 and Ch.5.)

Step 6 — Synthesized chapter principles

G2-P1: The Self (ātman) is deathless and unborn

The innermost reality is never born and never dies; it changes bodies as one changes garments. Grief over death mistakes the perishable body for the imperishable self.

Tier: FOUNDATIONAL · Domain: ATMAN-BRAHMAN · Covers: C1, C2 · Evidence: Gītā 2 · Untranslatable: ātman

G2-P2: Equanimity is the mark of wisdom (sthitaprajña)

The wise hold pleasure and pain, gain and loss, honour and shame, with a constant calm; the senses are reined in, "as the wise tortoise draws its four feet."

Tier: FOUNDATIONAL · Domain: EQUANIMITY · Covers: C3, C7 · Evidence: Gītā 2

G2-P3: Karma-yoga — act without attachment to the fruit

"Let right deeds be thy motive, not the fruit which comes from them." Disciplined, desireless action is itself yoga and bursts the bondage of works (karma-bandha).

Tier: FOUNDATIONAL · Domain: YOGA-PATHS+KARMA-SAMSARA · Covers: C4, C5 · Evidence: Gītā 2 · Untranslatable: yoga, karma

G2-P4: Desire, unchecked, destroys the mind

Brooding on sense-objects breeds desire, then passion, then recklessness, then ruin. The governed mind that holds its senses attains peace.

Tier: FOUNDATIONAL · Domain: DESIRE · Covers: C8 · Evidence: Gītā 2

G2-P5: Ritual reward-seeking is a lesser aim than fixity of soul

Clinging to the letter of scripture for heavenly reward leaves the soul unsteady; the goal is to rise above craving and the "pairs of opposites."

Step 8 — Quality

Coverage: the chapter's doctrinal content is densely captured.
Orphaned: <10%.
Principles: 5.
Traceability: 100%.

Step 9 — Validation

Standalone comprehension / claim-vs-warrant: G2-P2 (equanimity) and G2-P4 (unchecked desire ruins the mind) read as universal psychological/ethical claims. G2-P1 (the deathless ātman) is the sharpest cross-tradition node: the claim (there is an immortal soul) directly contradicts the Buddhist anattā (no abiding self) — same metaphysical question, opposite answer; and converges with Abrahamic soul-affirmation in claim, though the warrant (the soul's identity with brahman, Ch.7+) diverges from a created soul. G2-P3 (karma-yoga) converges with "duty for its own sake" but is warranted by saṃsāra/karma-bandha (rebirth-bondage), a frame-specific foundation. Note the near-verbatim parallel with Katha 2.18–19 ("This Self is never born, nor does It die… If the slayer thinks that he slays…") — a key Gītā↔Upanishad convergence anchor for the N=2 layer.
