What the term names
Kleśa — from the Sanskrit root kliś, to torment, to afflict — is the technical term in Patañjali's Yoga Sūtras for the cognitive-affective conditions under which the ordinary mind operates and to which the ordinary jīva's suffering is traced. The second chapter of the text, the Sādhana Pāda, names them: avidyā-asmitā-rāga-dveṣa-abhiniveśāḥ kleśāḥ — the kleśas are misperception, I-am-ness, attachment, aversion, and clinging to life (YS 2.3). The list is not casual. The five are presented in a structural order: avidyā — misperception of how things are — is the field, and the other four are the dispositional forms that misperception takes when the I-sense has crystallised inside it. Asmitā is the felt identification of consciousness with a particular instrument; rāga is the pulling toward what has produced pleasure; dveṣa is the pushing away from what has produced pain; and abhiniveśa — usually rendered clinging to life, more precisely the will to continue — is the deep, pre-cognitive insistence on the body's persistence that the text treats as observable even in those who otherwise consider themselves unattached. The architecture is consequential: working on rāga or dveṣa without working on the avidyā that produces them is, in the text's analysis, gardening above the root.
The five, more carefully
*Avidyā* is the foundational misperception — taking the impermanent as permanent, the unsatisfactory as satisfactory, the not-self as self, the impure as pure. Asmitā, I-am-ness, is the secondary error that builds on it: the consciousness Patañjali names puruṣa becomes confused with the *prakṛtic* instrument it perceives through, and a felt centre appears where, on the school's analysis, there had been only awareness aware of objects. Rāga and dveṣa are the affective pair the I-centre produces: once a separate me is in place, the field of experience sorts into what nourishes the me and what threatens it, and the conditioned mind organises itself around extending the first and excluding the second. Abhiniveśa is the most subtle of the five and the hardest to dislodge — the deep, pre-rational insistence on the body's continued existence that the Sūtras treat as observable in the universal animal flinch from death and in the way even the most reflective practitioner discovers, on examination, that the simple will to keep going has not entirely surrendered. The five are not separable in practice: the text treats them as the integrated operating system of the unfortified mind.
The path's relation to them
Patañjali does not call for the kleśas to be suppressed or refused — the text is careful that the move is more delicate than that. The two operative practices it names against them are abhyāsa — sustained, attentive repetition of the practice — and *vairāgya*, the gradual loosening of the binding force the affective pair exerts. The eight limbs of the aṣṭāṅga path — *yama* and *niyama* at the ethical floor, āsana and prāṇāyāma refining the bodily and respiratory ground, pratyāhāra turning attention inward, dhāraṇā, dhyāna and samādhi doing the inner work proper — are the structured curriculum under which the kleśas are thinned to what the Sūtras call their subtle form, in which they no longer produce action, and from there, in the longest reach of the path, to prasaṅkhyāna — the higher discernment the text describes as the condition for *kaivalya*. The Buddhist kilesa analysis (lobha, dosa, moha — greed, hatred, delusion) is a parallel taxonomy at the same diagnostic register; the kleśa schema of the Yoga Sūtras is the one the Indian yogic curriculum has been organised around for the last fifteen hundred years.
Where the analysis surfaces in the index
The kleśa vocabulary is technical and is more often referenced by its operative consequences than by name. Sadhguru's *Inner Engineering: A Yogi's Guide to Joy* and the Inner Engineering Online programme deliver the eight-limbed curriculum without foregrounding the Yoga Sūtra's Sanskrit list, but the diagnostic the curriculum is engineered against is the same: the asmitā-centred mind producing its own rāga and dveṣa, holding on to the body with abhiniveśa, and proceeding under avidyā the whole way. Sadhguru's longer-form lectures and his talk on disability and spiritual practice work the same diagnostic operationally — the move is from a kleśa-driven engagement with experience to a more recognisably puruṣa-stable one — without recourse to the technical vocabulary. Paramahansa Yogananda's *Autobiography of a Yogi* sits inside the kriyā lineage and treats the energetic-spinal work of kriyā as the operational thinning of the kleśas the Yoga Sūtras describe analytically — the same target by a different practical handle. Jon Kabat-Zinn's MBSR drops the Sanskrit but the body-scan and noting protocols are kleśa work in clinical idiom: noticing rāga and dveṣa arise without acting on them is precisely the abhyāsa discipline the Sūtras prescribe.
What it isn't
The kleśas are not, on the Yoga Sūtras' own reading, moral failings or character defects. The text treats them as the structural condition of the unfortified mind — the cognitive-affective architecture under which the jīva operates before the discipline has done its work — and the practitioner who hates herself for noticing rāga arising has compounded the kleśa with *asmitā* rather than addressed it. The list is also not synonymous with the Buddhist kilesa taxonomy, despite the cognate vocabulary and the obvious family resemblance — the Buddhist analysis works a threefold schema (lobha, dosa, moha) descending from a different diagnostic of how craving and aversion build *dukkha*, and the technical operations of the two paths are not interchangeable. And abhiniveśa in particular is sometimes misread as fear of death in the Western existentialist register: the text is more careful than that. Abhiniveśa is the positive will to continue, observable in the simple physical instinct to breathe again rather than only as the negative emotion of dread, and it is the most stable of the five because the body itself is its substrate.
