The kleshas are mental afflictions or emotional obscurations—greed, hatred, delusion, and their derivatives—that cloud awareness and perpetuate suffering. They are not moral failings but habitual patterns of reactivity that bind consciousness to cycles of suffering and rebirth. In Buddhist philosophy, liberating oneself from the kleshas is central to awakening.
Sanskrit kleśa (क्लेश) derives from the root klish, meaning 'to torment' or 'to afflict.' The literal sense is 'that which distresses,' encompassing both the affliction itself and the suffering it produces.
Kleshas — The Yoga Sutras of Patañjali use the identical Sanskrit term for five root afflictions (avidyā, asmitā, rāga, dveṣa, abhiniveśa) that obstruct the mind's union with the Self; the lists and mechanism differ slightly from Buddhism but share the diagnosis that ignorance and reactive emotion bind consciousness.
Passions, capital sins — Christian ascetic tradition identifies passions or vices—anger, greed, pride, envy—as distortions of the soul that separate it from God; the soteriological aim differs (union with divine love rather than nirvana), yet the diagnostic framework parallels the Buddhist map of inner obstacles.
Nafs (النفس), base self — The nafs—the ego-self prone to heedlessness, lust, and anger—functions similarly as the seat of spiritual affliction; Sufi practice aims to transmute these states through remembrance (dhikr) rather than analytical dismantling, but recognizes the same inner complexity.
Qi deviation, emotional excess — Taoist medicine and philosophy regard unbalanced emotional states—unresolved anger, fear, grief—as blockages to the flow of qi; the goal is not to eliminate emotion but to restore natural harmony and flow, a different framing but addressing the same inner dis-ease.
A practitioner meets the kleshas in real time through mindfulness: noticing the habitual tightening around a craving, the flare of aversion, the fog of self-deception that clouds clear seeing. Rather than fighting these patterns, Buddhist practice teaches observing them with compassion and wisdom, discerning their emptiness of solid selfhood, thereby loosening their grip on body and heart. Over time, this awareness gradually transforms reactivity into response.
What are the main kleshas?
Buddhist texts list three primary kleshas (greed/attachment, hatred/aversion, delusion) and their numerous derivatives; other schemas name five foundational ones. All are flavours of clinging and mis-knowing that distort perception and generate suffering.
Are the kleshas the same as sin?
No; kleshas are not moral transgressions but mental habits rooted in ignorance of how things truly are. The Buddhist framework is diagnostic and liberatory rather than guilt-based; a klesha is something to understand and release, not something for which one is damned.
Can the kleshas be completely eliminated?
Buddhist teaching affirms that full awakening (Buddhahood) involves the complete cessation of kleshas; for practitioners on the path, the work is gradual refinement and weakening of their hold, until ignorance itself is uprooted and suffering ends.
