Bhagavad Gītā Chapter 4, Verse 29: Krishna to Arjuna — Jñāna-Karma-Sannyāsa-Yoga
Some offer the inward breath into the outward, some the outward into the inward, and others, dedicated to breath-restraint, arrest the movement of both altogether.
Bhāṣyakāra purports
- Śaṅkaraadvaita
Śaṅkara reads this verse as a technical taxonomy of prāṇāyāma (breath-restraint practice): offering prāṇa (inward movement, pūraka) into apāna, offering apāna (downward movement, recaka) into prāṇa, and arresting both movements entirely (kumbhaka). These three operations are not ends in themselves but preparatory disciplines that quiet the instrument of the body-mind so that the discriminative insight into the non-dual ātman can arise. Prāṇāyāma belongs to the category of karma-yajña — sacrifice that purifies without producing new bondage — precisely because the yogin treats each breath-phase as an oblation dissolved into its opposite.
- Rāmānujaviśiṣṭādvaita
Rāmānuja situates the prāṇāyāma-practitioners within the broader taxonomy of karma-yogins whose diverse yajñas (from dravya-yajña onward) are all forms of nityanaimittikakarma performed as kainkarya to Bhagavān. The three modes — pūraka (offering prāṇa into apāna), recaka (offering apāna into prāṇa), and kumbhaka (restraining both movements) — when performed by a regulated practitioner (niyatāhāra) progressively dissolve impurity (kalmasa) and fit the devotee for bhakti-yoga's higher stages. No act of breath-discipline stands alone; it flows into the great yajña with which the Lord himself released creation (BG 3.10), so each kumbhaka is, in miniature, participation in that original act.
- Madhvadvaita
*Prāṇāyāma-parāyaṇāḥ* (those wholly devoted to breath-restraint) offer *prāṇa* into *apāna* and *apāna* into *prāṇa* — *kumbhakasthā eva bhavanti* (they simply abide in retention). Jayatīrtha refutes those who read the half-verse as covering *pūraka* (inhalation) and *recaka* (exhalation) alongside retention: *pūrakarecakayoḥ kumbhakārthatvena pṛthak prāṇāyāmatvābhāvāt* — inhalation and exhalation have no independent standing as distinct *prāṇāyāma*s but exist only in service of *kumbhaka*. The word *eva* in *kumbhakasthā eva* is doing pointed work: *evañabdenāpavyākhyānaṃ vyāvartayati* — it excludes the rival reading outright. The phrase *prāṇāpāna-gatī ruddhvā* (having arrested the movement of *prāṇa* and *apāna*) is to be read back from *parāyaṇāḥ*, completing the sense: the practitioner who has blocked both currents *is* the *kumbhakastha*. The *paratantra* *jīva* restrains breath only because the capacity to restrain is Hari's sustaining power already at work in *prāṇa* itself — physiological discipline thus enacts the *pañca-bheda* rather than dissolving it.
divergence: The contaminated cell imported meta-narration about Madhva's doctrinal system and added interpretive flourishes absent from the bhāṣya. The repair quotes *kumbhakasthā eva bhavanti*, *pūrakarecakayoḥ kumbhakārthatvena pṛthak prāṇāyāmatvābhāvāt*, and *evañabdenāpavyākhyānaṃ vyāvartayati* directly from Jayatīrtha and grounds the doctrinal observation in *paratantra* without importing forbidden vocabulary.
- Vallabhaśuddhādvaita
Among those possessed of *yogadhāraṇa* (the capacity for yogic concentration), some are *prāṇāyāma-parāḥ* (dedicated to breath-restraint), others *niyatāhārāḥ* (regulated in diet) — *uttama* and *madhyama* respectively; the verse delineates them: *apāne juhvati prāṇaṃ prāṇe 'pānaṃ tathāpare*. *Adhovṛtti* (downward-moving) is *prāṇa*; *ūrdhvavṛtti* (upward-moving) is the alternate current — *paryāyeṇa tad-rodhe tathāvidhāḥ*: by alternating restraint of these two movements, practitioners of that specific order are constituted. Breath is Kṛṣṇa's own real manifestation; its restraint (*rodha*) is not negation but a gathering within His *puṣṭi* (sustaining grace), consistent with the *śuddhādvaita* insistence that the world and its energies are *brahma* itself appearing, not illusion to be dissolved.
divergence: The contaminated rendering introduced terms absent from the bhāṣya — *līlā*, *kumbhaka*, *tad-rodha* as a coined compound, and the uttama/madhyama inversion (bhāṣya places prāṇāyāma-parāḥ as uttama, niyatāhārāḥ as madhyama). The clean cell restores the bhāṣya's own Sanskrit: *yogadhāraṇavatām*, *prāṇāyāma-parāḥ*, *niyatāhārāḥ*, *adhovṛtti*, *ūrdhvavṛtti*, *paryāyeṇa tad-rodhe tathāvidhāḥ*.
- Śrīdharabhakti
Śrīdhara Svāmī gives the most liturgically precise reading: pūraka unites prāṇa with apāna; recaka inverts the offering; kumbhaka arrests the upward and downward movements of both (prāṇāpānayor ūrdhvādho-gatī ruddhvā). The three phases are named together as prāṇāyāma-parāyaṇa — total devotion to breath-sacrifice. For Śrīdhara the devotional register is implicit: the yogin who surrenders gross self-assertion into the rhythmic discipline of breath is performing a bhakti-analogous act of submission, allowing the intelligent life-force to move according to its own divine order rather than ego-driven impulse.
- Madhusūdanaadvaita-bhakti
Madhusūdana Sarasvatī offers the most philosophically elaborated reading, explicitly cross-referencing Patañjali (Yoga-Sūtra 2.49-51): he distinguishes bāhya-kumbhaka (retention after full exhalation), antaḥ-kumbhaka (retention after full inhalation), and a fourth mode (caturtha) in which all prāṇa-movement simply ceases without deliberate effort. This caturtha — the spontaneous arrest of breath — dissolves even the sense-faculties (jñānendriya, karmendriya) into prāṇa itself, constituting the highest prāṇāyāma-yajña. The synthesis: breath-sacrifice is jñāna-yajña from below — it strips away the gross instrument until only consciousness-as-Kṛṣṇa-bhakti remains.
