What the term compresses
The Sanskrit compound saṃ-yama — saṃ (together), yama (restraint, holding) — is Patañjali's name for the three inner limbs of the aṣṭāṅga path treated not as discrete techniques but as a single graded continuum. The three are dhāraṇā, the binding of attention to a chosen object; dhyāna, the sustained unbroken contemplation of that object once the binding holds; and samādhi, the absorption in which the apparatus of subject-knowing-object collapses into the contemplation itself. The classical text takes the unusual step of giving the three a single collective name — saṃyama — and treating them, from limb six onward, as one continuous depth-axis rather than as a sequence of separate practices to be mastered serially. The pedagogical claim is that the practitioner who has stabilised dhāraṇā on an object is already on the dhyāna–samādhi continuum; what the Sūtras describe is less a staircase than a tilt, a continuous deepening into the same investigation. The earlier five limbs — yama, niyama, āsana, prāṇāyāma, pratyāhāra — are the external preparation; saṃyama is the inner work itself.
How the Sūtras use it
The third pāda of the Yoga Sūtras — the Vibhūti-pāda (the book on the powers) — uses saṃyama as a structural verb. Aphorism after aphorism takes the form by saṃyama on X, knowledge or capacity Y arises: saṃyama on the moon's path, knowledge of the arrangement of the stars; saṃyama on the nature of strength, the strength of an elephant; saṃyama on the latent impressions, knowledge of previous births. The catalogue is famously long and famously discomfiting, and the same classical commentary that records it inserts a careful warning at III.37: these capacities arise as obstacles to samādhi when the practitioner emerges from absorption, though they pass for accomplishments in everyday awareness. The point of the catalogue is not that the powers should be cultivated; the point is that when saṃyama is sustained on any chosen object, the practitioner enters a depth of cognition the ordinary mind does not access, and the text is honest about what arises there. The Sūtras' answer to the risk the chapter describes is the orientation of vairāgya — dispassion — and the orientation of kaivalya — the recognition that any cognised content is still on the prakṛti side and therefore not yet the operative goal. The same instrument that produces the powers is the instrument that produces, when the practitioner declines to grasp them, the disentanglement of puruṣa from what it has been knowing.
In the index
The classical text is not present in the index as a standalone row, but the saṃyama continuum reaches contemporary practice through several voices. Sadhguru's *Inner Engineering: A Yogi's Guide to Joy* and the Inner Engineering Online programme walk the aṣṭāṅga architecture as a single working curriculum, with the inner three limbs presented as a depth-axis rather than as discrete tools — the Shambhavi Mahamudra practice the programme delivers is structurally a saṃyama on a chosen point inside a structured preparation. Sadhguru's longer-form lectures, the talk on disability and spiritual practice and the talk on unlocking the mind's full potential repeatedly identify the continuous inner depth-work as the practice the postural-yoga industry has obscured. Paramahansa Yogananda's *Autobiography of a Yogi* carries the kriyā yoga lineage's version of saṃyama — the kriyā technique is, in the classical idiom, a sustained directed-attention practice on the breath and on points along the spinal axis, treated as a single continuum rather than as three separate methods. From the secular descent, Jon Kabat-Zinn's MBSR programme carries the dhāraṇā–dhyāna continuum into a clinical eight-week curriculum, with the samādhi end of the continuum left undescribed but operationally pointed at. Adyashanti's *True Meditation* gives the most explicit English-language instructional sequence for the inner three limbs as a single continuum, and his *Do Nothing* approaches the same depth from the self-enquiry door — the recognition that the saṃyama continuum is not the only configuration attention can take is, in the Sūtras' own idiom, the para-vairāgya limb that lets the directed-attention apparatus be set down without abandoning the depth it has trained.
What it isn't
Saṃyama is not a separable technique. The whole point of the compound is that the three limbs it names are operationally one — describing dhāraṇā in isolation, or samādhi in isolation, treats the continuum as if it could be broken into modules, which is a category error in the Sūtras' own terms. Saṃyama is also not synonymous with samādhi alone, despite the frequent loose usage in English: samādhi is the deep end of the continuum, saṃyama is the continuum itself. The contrast with vipassanā in the Buddhist Theravāda lineage is structural. Vipassanā uses concentration as the platform from which a different operation — investigation of the three marks — is conducted; saṃyama in the Sūtras is the sustained concentrative depth itself, with the discrimination of puruṣa from prakṛti the recognition that the depth makes possible. The two architectures share the dhāraṇā foundation and diverge at what the foundation is for. Neither is the secular focused attention of contemporary mindfulness vocabulary, which extracts the technique from the doctrinal frame that gave it its content.
