Citta — rendered variously as 'mind-stuff,' 'mental substance,' or simply 'mind' — occupies a structural center in the depth-psychological reading of Patañjali's Yoga Sūtras, where it designates neither a disembodied intellect nor a Cartesian res cogitans but a dynamic, material-processual substrate from which all mental activity emerges. Within the corpus, citta is treated as an evolute of prakṛti, composed of the three guṇas, and thus fundamentally distinct from puruṣa, the witnessing consciousness. The definitional tension most thoroughly elaborated is precisely this relation: citta modifies itself into the forms of perceived objects, yet it is not itself aware — its animation depends entirely on the reflected light of puruṣa. Bryant's commentary, drawing on Vyāsa, Vācaspati Miśra, Vijñānabhikṣu, and Bhoja Rāja, makes plain that yoga is formally defined as the cessation (nirodha) of citta's vṛttis — its permutations, thought-sequences, and cognitive states — including deep sleep. A further major axis concerns the ontological status of created minds (nirmāṇa-cittas) and the relationship between samskāra, vāsanā, and the citta as repository of subliminal impressions. The term thus serves as the decisive hinge between Sāṃkhya metaphysics and the practical psychology of liberation, and its correct understanding is prerequisite to grasping samādhi, kaivalya, and the entire soteriological arc of the Yoga school.

it is the citta that changes and modifies itself according to the objects of perception — pots or any other objects of the world — molding itself into a replication of these objects... This transformed citta... is presented to the changeless and eternal puruṣa.
This passage establishes the core Yoga metaphysics of citta: it is a plastic, self-modifying substance whose forms are presented to puruṣa, which itself remains unchanged — an argument that grounds the entire epistemology of yogic perception.

yoga is the cessation (nirodha) of the activities or permutations (vṛttis) of the citta. The vṛttis refer to any sequence of thought, ideas, mental imaging, or cognitive act performed by the mind, intellect, or ego.
Bryant articulates Patañjali's formal definition of yoga as the stilling of citta's vṛttis, grounding the entire practical system in the ontology of citta as a physical, mold-taking mental substance distinct from the soul.

Vijñānabhikṣu states that the citta is the one unified internal organ, and this becomes manifest in the various functions of intelligence, ego, and mind because of vṛttis.
Vijñānabhikṣu's position — that citta is a single unified internal organ differentiating into buddhi, ahaṃkāra, and manas through its vṛttis — is presented here as the authoritative synthetic definition within the classical commentary tradition.

the memory of having slept well must relate to a state of mind experienced during deep sleep, which is recorded in the citta as memory and remembered upon awakening. This state of mind according to this line of reasoning must therefore pertain to a category of vṛtti distinct from others.
The passage argues, against Vedāntic dissent, that deep sleep constitutes a genuine vṛtti of the citta, because memory of sleep quality requires a prior citta-state as its cause — an argument that extends citta's scope to cover all mental states without exception.

hṛdaye, on the heart; citta, the mind; saṃvit, knowledge — [By saṃyama] on the heart, knowledge of the mind ensues.
Sūtra III.34 locates citta-knowledge as the result of saṃyama on the heart, linking the technical yogic practice of samyama to direct gnosis of the mind's nature and implicitly connecting citta to the ātman's abode in Upaniṣadic physiology.

nirmāṇa-cittāny asmitā-mātrāt — Created minds are made from ego only. ... pravṛtti-bhede prayojakaṃ cittam ekam anekeṣām — There is one mind, among the many [created by the yogī], which is the director in the different activities.
Sūtras IV.4–5 introduce the concept of nirmāṇa-cittas — multiply created minds originating from ego alone — governed by a single directing citta, raising questions about the individuation and multiplicity of citta that the commentary tradition addresses at length.

vāsanā might best be taken to refer to those innate saṃskāras that remain dormant in this life... and saṃskāra to impressions and thoughts that are constantly being generated in this lifetime.
The distinction between vāsanā and saṃskāra is clarified here in relation to citta's role as the repository of both latent and actively generated impressions, a distinction central to understanding how citta conditions karmic continuity across lives.

the radiant and effulgent characteristics of sattva pervading the yogī's citta, and emanating out due to transcending the limitations of the kleśas.
Sattva's natural luminosity, manifest in the yogī's citta when the kleśas are transcended, is here invoked to explain the physical phenomenon of the aura, illustrating how citta's guṇic composition has direct somatic and phenomenological consequences.

The Sanskrit index entries confirm citta's recurrence at structurally pivotal sūtras — notably IV.19 on citta's own luminosity (svābhāsa) — situating it among the most frequently indexed technical terms in the Yoga Sūtras.

when the influences of rajas and tamas have been eliminated, the mind's natural quality of sattva can manifest without disturbance. Sattva, in addition to producing a sustainable experience of happiness... is by nature pure.
Vācaspati Miśra's account of the mind's sattvic nature, clarified when rajas and tamas are subdued, situates citta's purification as both the precondition and the telos of the ascending stages of dispassion culminating in puruṣa-khyāti.

Once freed from its association with the states of the mind, the soul can abide in its own nature, the highest state of pure consciousness, asamprajñāta-samādhi.
The passage frames liberation as the puruṣa's disentanglement from citta's states, using Vijñānabhikṣu's three possibilities to argue that the Yoga school identifies freedom with consciousness resting in itself, not with citta's cessation as annihilation.

the wisdom-bearing saṃskāras destroy only the dormant and unmanifest store of karma, and not the prārabdha-karma, the karma that has already activated.
In explaining samādhi's differential effect on karma, this passage implicitly treats citta as the storehouse where dormant saṃskāras reside, underscoring its function as the medium through which karma is both accumulated and dissolved.
