What are the Three Poisons?
The Three Poisons are greed (lobha), hatred (dosa), and delusion (moha): the three root unwholesome states in Buddhist analysis, identified as the engine of *dukkha* and the cause of continued existence in saṃsāra. They are traditionally depicted at the centre of the Tibetan [bhavacakra](lexicon:bhavacakra) as a rooster, a snake, and a pig biting one another's tails, each poison feeding the next.
Not a moral code
The three poisons are not, on Buddhist analysis, moral failings to be condemned. They are the structural condition of the unawakened mind and the field on which the path operates. Their cessation is not a matter of suppressing greed and hatred by force of will. That approach is just more dosa with a virtuous label. What removes them is the [vipassanā](lexicon:vipassana) insight which takes away the me whose interests the affective pair was advancing. The three poisons also differ from the [kleśas](lexicon:kleshas) of Patañjali's *Yoga Sūtras*. Patañjali identifies five afflictions rather than three and assigns [avidyā](lexicon:avidya) (misperception) the same root-level role that moha plays here. The two frameworks diagnose similar territory, but the technical operations of the two paths are not interchangeable.
What the analysis claims
Buddhist diagnosis is structured as a clinical chain. [Dukkha](lexicon:dukkha) is the symptom: the structural unease of conditioned existence. The cause is craving driven by misperception, and that compound is what the three poisons (akusala-mūla in Pāli, the unwholesome roots) name and unpack. Lobha is the pulling toward what is taken to nourish the me: attachment to objects, to states, to identities, to particular outcomes. Dosa is the pushing away from what is taken to threaten the me: aversion, irritation, ill-will, the felt rejection of present experience. Moha is the cognitive confusion under which the first two operate. It is the misperception that there is a separable me in the first place, whose nourishment and protection the other two are working toward.
Why three rather than two
On their own, the two affective movements, toward and away, would be a familiar enough picture of how the mind organises around pleasure and pain. The analytical move that makes the Buddhist diagnosis distinctive is the third item. Moha is not simply ignorance in the sense of a missing piece of information; it is the basal misperception that produces the me whose interests lobha and dosa are then doing the work of advancing. The three are not parallel afflictions to be addressed independently; they are a single architecture in which the cognitive error generates the affective pair, and the affective pair reinforces the cognitive error. Working on the surface symptoms without addressing the misperception that produces them is, on this analysis, the spiritual equivalent of medicating an infection without treating its source.
The opposing virtues
Each poison has a traditional antidote at the next level of the path. Lobha is opposed by dāna (generosity) at the ethical level and by vairāgya (dispassion) at the meditative level. Dosa is opposed by [mettā](lexicon:metta) (loving-kindness) and by karuṇā (compassion), the first two of the four [brahmavihāras](lexicon:brahmaviharas), the divine abidings. Moha is opposed by paññā (wisdom), specifically the wisdom that arises from sustained [vipassanā](lexicon:vipassana) practice and that sees, eventually and directly, that the me whose nourishment the first two were serving is itself a construction. This is the *anatta* recognition, the hinge on which the entire path turns. The structure of the path follows the structure of the diagnosis: ethics undermines the gross expressions, meditation undermines the affective grip, insight undermines the cognitive root.
Where the analysis surfaces in the index
The three poisons rarely appear under their Pāli names in contemporary English-language teaching, but the diagnostic does most of the structural work whenever the Buddhist analysis of why practice is being undertaken is made explicit. Tara Brach's guided practices walk practitioners through lobha and dosa as they arise in immediate experience. The RAIN sequence (recognise, allow, investigate, nurture) is, in effect, kilesa work in clinical idiom. Thich Nhat Hanh on emptiness, signlessness and aimlessness addresses moha directly, taking it as the basal misperception the Mahāyāna doctrines of śūnyatā are meant to dislodge. Br. Troi Duc Niem's reflection from Plum Village holds the same three coordinates from inside the practising community. Pema Chödrön's *When Things Fall Apart* reframes dosa as the precise place where the practice becomes operative: the reflexive aversion to groundlessness is the field rather than the obstacle. Jon Kabat-Zinn's MBSR translates the moha/dosa diagnosis into the body-scan and noting protocols used in secular clinical mindfulness.
