Karma in the Yoga Sutras: karmashaya, the kleshas, and neither white nor black

Why the Yoga Sutras treat karma differently

Patanjali's Yoga Sutras approach karma neither as a ritual mechanism (the Mimamsa concern) nor primarily as an ethical dilemma about acting rightly in the world (the Gita's concern), but as a psychological structure to be analysed and, ultimately, dismantled through practice. The text is interested in exactly how action leaves its trace, what kind of trace it leaves, and what changes about that trace when a person's practice reaches a certain depth. This makes the Sutras' treatment more technical, and arguably more precise, than anywhere else in the classical yoga corpus, and it rewards close reading of the actual Sanskrit terms rather than loose paraphrase.

Karmashaya: the reservoir, rooted in klesha

The key term is introduced at Yoga Sutra 2.12: klesha-mulah karmashayo drishta-adrishta-janma-vedaniyah — "the reservoir of karma (karmashaya), rooted in the kleshas, is to be experienced in births seen and unseen." Several precise claims are packed into this single sutra. First, karma is described here not simply as scattered individual acts but as a reservoir (ashaya, literally a resting place or receptacle) — a cumulative structure, echoing the sanchita concept discussed in Vedanta teaching (see types-of-karma) though developed here in Patanjali's own technical vocabulary. Second, and distinctively, this reservoir is said to be rooted in the kleshas — the afflictions catalogued at Yoga Sutra 2.3 as avidya (fundamental misperception), asmita (I-am-ness, ego), raga (attraction), dvesha (aversion) and abhinivesha (clinging to life, fear of death). This is a specific causal claim: karma does not arise from action as such, in Patanjali's analysis, but from action performed under the influence of these afflictions. Third, the reservoir's fruit is said to be experienced across both "seen" — the present, visible life — and "unseen" births, i.e. future lives not currently perceptible.

The significance of rooting karmashaya in the kleshas, rather than treating karma as an independent force, is enormous for the rest of the text's programme. If karma's binding power derives from the kleshas rather than existing independently, then addressing the kleshas directly — through the whole apparatus of practice the Sutras describe, including discrimination (viveka) and the eightfold path — becomes the relevant lever, rather than any attempt to directly manage or manipulate karma itself. This is a structurally important move: it makes karma, in Patanjali's system, downstream of a deeper psychological cause rather than a free-standing metaphysical mechanism to be negotiated on its own terms.

Three kinds of fruit

Yoga Sutra 2.13 specifies what karmashaya produces as long as its root, the kleshas, remains: sati mule tad-vipako jaty-ayur-bhogah — "the root existing, its fruit is birth, lifespan and experience." These three — jati (the kind of birth, the species or circumstance one is born into), ayus (the duration of that life), and bhoga (the experiences, pleasant and painful, that fill it) — are presented as the complete scope of what karmic ripening determines. This is a notably restrained and specific claim compared to some popular renderings of "karma decides everything about your life": Patanjali specifies three particular parameters, not an unlimited, all-encompassing determinism over every detail of experience.

Samskara and vasana: how the reservoir is built and expressed

Two further technical terms, discussed at length elsewhere in the Sutras (see /resources/glossary), explain the mechanics connecting action to karmashaya. A samskara is the subtle impression left in the mind by any experience or action — not the karmic residue in the moral sense directly, but the psychological trace that makes repetition, memory and habitual tendency possible at all. Vasana refers to the latent tendency or dispositional pattern that accumulates from repeated samskaras — the "flavour" (the literal sense of the word) that colours future mental activity and behaviour based on the past. Yoga Sutra 4.8 connects vasanas directly to the ripening of karmic fruit corresponding to their nature: tatas tad-vipakanuguninam eva abhivyaktir vasananam — "from that [ripening] there is manifestation only of those vasanas that are appropriate to that fruition." Together, samskara and vasana form the operative machinery by which karmashaya, once accumulated, expresses itself as a person's habitual patterns and, ultimately, as the shape of future experience.

Yoga Sutra 4.7: neither white nor black

Perhaps the single most distinctive and technically interesting statement on karma anywhere in the yoga literature comes at Yoga Sutra 4.7: karma-ashuklakrishnam yoginah trividham itaresham — "the karma of a yogin is neither black nor white; for others, it is of three kinds." This sutra distinguishes ordinary human action, categorised elsewhere in Indian ethical thought as broadly falling into black (harmful, generating suffering), white (beneficial, generating merit), or mixed varieties, from the action of an accomplished yogin, which is said to belong to none of these categories. This is not a claim that the yogin acts wrongly or amorally — it is a claim, consistent with Yoga Sutra 2.12's rooting of karmic bondage in the kleshas, that action performed without the afflicted motivations of craving, aversion, ego-identification and fear that generate ordinary binding karma simply does not generate karmic residue of the usual binding kind, whether "good" or "bad." This closely parallels, though in Patanjali's own distinct vocabulary, the Gita's argument at 4.18 that action performed without attachment differs in kind, not merely in outward appearance, from ordinary binding action — the two texts converge on a structurally similar insight while using different technical apparatus to state it.

Reading Patanjali's precision honestly

What makes the Yoga Sutras' treatment worth taking seriously on its own terms, rather than folding it into a generic "yoga says karma exists" statement, is exactly this precision: a specific causal chain (klesha → karmashaya → jati/ayus/bhoga, mediated by samskara and vasana), and a specific, carefully worded exception for the case of accomplished practice (4.7). This is analytic philosophy of mind and action dressed in the vocabulary of classical Sanskrit soteriology, and it rewards being read slowly, sutra by sutra, rather than being summarised as a single vague sentence about karma and yoga. Scholars including Karl Potter and Mircea Eliade, in his early study of Patanjali's system, have both noted how unusually systematic this part of the Sutras is compared with the more devotional or narrative treatments of karma found elsewhere in the classical corpus.

Vyasa's Yoga Bhashya: filling in the mechanism

Patanjali's sutras are famously compressed, and much of what readers take to be 'the Yoga Sutras' account of karma' actually comes from Vyasa's Yoga Bhashya, the oldest surviving commentary, without which several of the terse sutras discussed above would be nearly opaque. On 2.13, Vyasa distinguishes karma that produces a single birth from karma requiring several births to exhaust, a classification discussed in more detail at types-of-karma, and he works through concrete cases of how several karmic causes accumulated at different times can combine to shape one birth's particular jati, ayus and bhoga together, rather than each fruit having a single, separately traceable cause. On 4.7, Vyasa clarifies that the yogin's karma is called neither black nor white specifically because it is performed without the desire for its fruit and without the ignorance that ordinarily binds an act to a future result — tying the sutra explicitly back to the klesha-rooted account of 2.12 rather than leaving 'neither white nor black' as an unexplained special case. Reading Patanjali without Vyasa is possible but considerably harder; the commentary is where the terse sutra-level claims about karmashaya receive the worked argument that makes them cohere as a single system rather than a list of separate technical terms.
