What is Kleśas?
Kleśa (Sanskrit root kliś: to torment, to afflict) is the technical term in Patañjali's Yoga Sūtras for the five conditions that hold the mind in suffering. The second chapter, the Sādhana Pāda, names them: avidyā (misperception), asmitā (I-am-ness), rāga (attachment), dveṣa (aversion), and abhiniveśa (clinging to life) (YS 2.3). Avidyā is the foundational misperception; the other four are the forms it takes once a sense of self has crystallised inside it. Working on rāga or dveṣa without working on the avidyā beneath them is, in the text's own analysis, gardening above the root.
Kleśas vs related concepts
The kleśas are not moral failings or character defects. The Yoga Sūtras treat them as the structural condition of the unfortified mind, the architecture under which the jīva operates before practice has done its work. A practitioner who hates herself for noticing rāga arising has compounded the kleśa with *asmitā* rather than addressed it. The list is also distinct from the Buddhist kilesa taxonomy. Despite the cognate vocabulary, the Buddhist analysis works a threefold schema (lobha, dosa, moha: greed, hatred, delusion) that descends from a different account of how craving and aversion build *dukkha*; the technical operations of the two paths are not interchangeable. Abhiniveśa is sometimes misread as fear of death in the Western existentialist sense. The text is more precise: abhiniveśa is the positive will to continue, observable in the physical instinct to breathe again, not only as the emotion of dread. It is the most stable of the five because the body itself is its substrate.
The five kleśas
*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 calls puruṣa becomes confused with the *prakṛtic* instrument it perceives through, and a felt centre appears where there had been only awareness aware of objects. Rāga and dveṣa are the affective pair the I-centre produces. Once a separate self is in place, experience sorts into what nourishes it and what threatens it, and the conditioned mind organises itself around extending the first and excluding the second. Abhiniveśa is the most subtle and the hardest to dislodge. It is the pre-rational insistence on the body's continued existence, observable both in the universal animal flinch from death and in the way even the most reflective practitioner finds, on examination, that the simple will to keep going has not entirely surrendered. The text treats the five as the integrated operating system of the unfortified mind.
The path's response
Patañjali does not prescribe suppression. The move is more careful. The two operative practices the text names against the kleśas are abhyāsa, sustained attentive repetition, and *vairāgya*, the gradual loosening of the pull the affective pair exerts. The eight limbs of the aṣṭāṅga path provide the full curriculum: *yama* and *niyama* at the ethical ground, āsana and prāṇāyāma refining the body and breath, pratyāhāra turning attention inward, and dhāraṇā, dhyāna, and samādhi doing the inner work. Under this structure, the kleśas are thinned to what the Sūtras call their subtle form, where they no longer produce action. In the longest reach of the path, this leads to prasaṅkhyāna, the higher discernment the text names as the condition for *kaivalya*. The kleśa schema has been the organising framework of the Indian yogic curriculum for roughly fifteen hundred years.
In the index
The kleśa vocabulary tends to surface by its operative consequences rather 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 Sanskrit list, but the diagnostic is the same: the asmitā-centred mind producing rāga and dveṣa, holding on through abhiniveśa, and operating throughout under avidyā. Sadhguru's longer-form lectures and his talk on disability and spiritual practice work the same diagnostic, moving from kleśa-driven engagement to a more puruṣa-stable one, without recourse to the technical terms. Paramahansa Yogananda's *Autobiography of a Yogi* sits within 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 means. Jon Kabat-Zinn's MBSR drops the Sanskrit entirely, 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.
