The grammar of the term
Nirodha is built from the prefix ni (down, into, within) and the verbal root rudh (to obstruct, to restrain, to enclose) — the literal image is of a containment from below or within, the closing of a movement back into the ground from which it had risen. The Sanskrit and the Pāli share the form. The term operates as a technical noun across two of the major contemplative-theoretical corpora of the Indian world. In the [Yoga Sūtras](lexicon:yoga-sutras) of Patañjali it names the settling of *citta*–*vṛtti* — the modifications of the inner cognitive instrument — under which the text's foundational claim is stated: yogaś citta-vṛtti-nirodhaḥ (I.2), yoga is the cessation of the modifications of mind-stuff. The whole eight-limbed *aṣṭāṅga* the Sūtras lay out is the curriculum the second sūtra names the goal of. In the Buddhist corpus the term operates inside the analytic architecture of the Four Noble Truths. Dukkha-nirodha — the cessation of *dukkha* — is the third of the four truths, the prognosis in the medical structure the Buddha laid out at the Deer Park in Sarnath. The first truth names the symptom; the second names the cause (samudaya — the arising of craving conditioned by ignorance); the third names the prognosis (nirodha — the cessation is possible, and is what *nirvāṇa* names); the fourth names the treatment (magga — the Eightfold Path). The shared grammar across the two corpora is operative: a movement the practitioner is presently engaged in can be brought to a stop, and the path is the discipline under which the stopping becomes lived rather than merely conceived.
The Yogic register
In the Yoga Sūtras, nirodha names the operative goal of the entire eight-limbed curriculum. The architecture is engineered so that the prior limbs make the settling possible at the inner stages: the *yamas* and *niyamas* set the ethical and dispositional floor; *āsana* and *prāṇāyāma* prepare the body and the breath; *pratyāhāra* withdraws the senses from their ordinary objects; the inner three limbs (*dhāraṇā*, *dhyāna*, *samādhi*) work on the modifications directly. The nirodha the second sūtra names is not the production of a vacant cognitive field but the dropping of the misidentification of the witness with the moving content — the classical commentary is unambiguous on this point. The text's metaphysical scaffolding is the Sāṃkhya dualism, under which *citta* and its *vṛttis* are both on the *prakṛti* side of the cosmological cut, and the recognition the curriculum produces is *kaivalya* — the disentanglement of *puruṣa* from what it had been mistaken for. The Vyāsa commentary on I.2 distinguishes two grades of nirodha: vyutthāna-nirodha, the settling of grosser modifications that occurs at the lower stages of *samādhi*, and nirodha-pariṇāma, the deeper structural shift in citta under which the field itself becomes available rather than only its momentary calmings.
The Buddhist register
In the Pāli canon and the surrounding Theravāda and Mahāyāna commentaries, nirodha operates inside the analytic vocabulary of the Four Noble Truths. The Buddha's first sermon at Sarnath introduces dukkha-nirodha as the third truth — the cessation of *dukkha* is possible, and is what *nirvāṇa* names — and the classical commentary specifies the operative relation: the third truth is to be realised, not produced. The mechanism the Buddhist analysis names is the unwinding of *dependent origination* — the twelve-link chain through which *avidyā* (ignorance) conditions *saṃskāras* (formations), which condition consciousness, name-and-form, the sense-bases, contact, feeling, craving, clinging, becoming, birth, and aging-and-death — under the recognition that any link can be the point at which the chain stops being followed. The same vocabulary recurs in the saññāvedayita-nirodha of the Theravāda *jhāna* literature — the cessation of perception and feeling, the deepest of the formless attainments — and in the saṅkhāra-nirodha of the *vipassanā* curriculum, the unwinding of the formations the practitioner has been observing arise and pass. The technical machinery diverges from the Yogic; the operative claim about cessation as a workable goal of contemplative practice does not.
In the index
The nirodha analysis reaches the corpus through teaching streams in both registers. Sadhguru's *Inner Engineering: A Yogi's Guide to Joy* and the Inner Engineering Online programme deliver the eight-limbed scaffold the Yogic nirodha operates inside; his longer-form lectures, his talk on disability and spiritual practice and the talk on unlocking the mind's full potential carry the citta-vṛtti-nirodhaḥ claim into accessible English without naming the technical aphorism the work is downstream of. Paramahansa Yogananda's *Autobiography of a Yogi* carries the kriyā-yoga lineage in which the Sūtras' architecture is the operating system on which the more esoteric techniques run. Adyashanti's *True Meditation* gives the cleanest English-language instructional sequence for the inner-three-limb continuum under which nirodha-pariṇāma becomes available, and his *Do Nothing* approaches the same depth from the opposite vector — by setting every technique aside, the nirodha that does not require effort to occur becomes the working ground rather than the produced result. Rupert Spira's *Being Aware of Being Aware* translates the recognition into non-dual register: the witness in which the modifications occur was always available, the nirodha is the dropping of the misidentification rather than the production of a vacant field. The Buddhist register reaches the corpus through Jon Kabat-Zinn's MBSR programme, which translates the dukkha-nirodha claim into the clinical attention-training register the eight-week protocol carries; Tara Brach and Jack Kornfield's *Power of Awareness*, which works the Eightfold Path operations through a contemporary *vipassanā* curriculum; and Pema Chödrön's *When Things Fall Apart*, which carries the Vajrayāna treatment of the same operation under the rubric of *groundlessness*. Thich Nhat Hanh on emptiness, signlessness and aimlessness and Br. Troi Duc Niem's reflection from Plum Village carry the Mahāyāna inflection — the same dukkha-nirodha read through the Madhyamaka analysis of *emptiness* the lineage descends from.
What the term isn't
Nirodha in the Yogic register is not the cessation of cognitive content — the standard misreading the popular reception has imported from second-hand readings of Sūtra I.2 — but the cessation of the misidentification of the witness with the moving content. The classical commentary is consistent that a practitioner who has produced a temporarily vacant cognitive field but has not seen through the misidentification has done the lower-grade version of the operation rather than the one the Sūtras' architecture is engineered toward. Nirodha in the Buddhist register is not annihilation in the cosmological sense the early Western reception sometimes read *nirvāṇa* as — the Pāli canon is explicit that dukkha-nirodha is the cessation of *dukkha*, the cessation of the configuration under which experience is felt as unsatisfactory, rather than the cessation of experience itself. And the two registers are not interchangeable on closer inspection: the Yogic nirodha operates inside the Sāṃkhya dualism it inherits, in which the witness is plural and the field it observes is prakṛti; the Buddhist nirodha operates inside the *anattā* analysis, in which the witness the Yogic vocabulary posits is itself one of the configurations the path is engineered to see through. The cognates are real, the operative move is recognisably shared, and the doctrinal architecture the move sits inside differs. Mapping across the two registers loosely — as if the *kaivalya* of the Sūtras and the *nirvāṇa* of the canon named the same recognition — is the standard simplification the popular contemplative reception has produced and the technical commentary tradition has consistently declined to ratify.
