The four
The list is short and the order matters. [Mettā](lexicon:metta) — usually rendered loving-kindness but more accurately the active wish that beings be well — is the first. Karuṇā — compassion, the wish that beings be free of suffering — is its complement, addressed to the same field but pointed at the suffering rather than the welfare of the beings. Muditā — sympathetic joy — turns the same attention to the happiness of others and meets it with gladness rather than the comparison and envy that ordinary mind tends to produce. Upekkhā — equanimity — is the steadiness that holds the previous three when conditions go in directions the practitioner did not want. The classical analysis treats the four as a single integrated curriculum rather than as alternative postures: they are the abodes (vihāra) the trained mind dwells in once it can dwell anywhere by choice.
The classical analysis
Each of the four is taught with a near enemy and a far enemy — the qualities that masquerade as the brahmavihāra and the qualities that defeat it. The near enemy of mettā is attachment (it looks like loving-kindness but operates from grasping); the far enemy is ill-will. The near enemy of karuṇā is sentimental pity (it cohabits with self-importance); the far enemy is cruelty. The near enemy of muditā is the relief one feels at one's own escape from a difficulty (a comparative move masquerading as joy); the far enemy is jealousy. The near enemy of upekkhā is indifference; the far enemy is the grasping-and-aversion that ordinary mind oscillates between. Buddhaghosa's Visuddhimagga is the canonical source for the analysis and the manual the Theravāda tradition has carried since. The practical instruction is to cultivate each brahmavihāra in a graded sequence of objects — beginning with oneself or a benefactor, extending to a friend, then a neutral person, then a difficult person, then to all beings — until the quality is no longer a state directed at a chosen object but the steady-state colouring of attention itself.
The Mahāyāna register
The same four travel into Mahāyāna as the Four Immeasurables (apramāṇa). The change in name is not cosmetic: in the bodhisattva framework the practice is no longer aimed at the practitioner's own vihāra but at the welfare of all sentient beings without limit, and the four become the affective ground of bodhicitta — the awakened intention from which the bodhisattva acts. The Tibetan curriculum makes the connection explicit by sequencing the tonglen and lojong practices on the brahmavihāra foundation; the breath-based exchange of self-and-other in tonglen is intelligible only on a mind that has done enough karuṇā and upekkhā to bear what the practice asks it to take in. The Vietnamese Thiền lineage of Thich Nhat Hanh uses the four under the older Pāli heading and treats interbeing as the philosophical ground that makes each of them coherent in the first place.
In the index
Tara Brach and Jack Kornfield's *Power of Awareness* is the index's clearest sustained practice of the brahmavihāras in the IMS-Theravāda register; Brach's guided sessions repeatedly close on a mettā phase rendered in unadorned English. The Plum Village teaching and Thich Nhat Hanh on emptiness, signlessness and aimlessness carry the four immeasurables in Mahāyāna idiom — love meditation in TNH's vocabulary is the brahmavihāra curriculum without the Pāli terminology. Pema Chödrön's course on awakening compassion and *When Things Fall Apart* sit on the Tibetan side: the tonglen and lojong instruction the books transmit assumes the brahmavihāra foundation even where the Sanskrit term is not introduced. Jon Kabat-Zinn's MBSR carries the secular descendant — the loving-kindness phase that increasingly appears in clinical eight-week curricula is mettā under a non-religious name.
What it isn't
The brahmavihāras are not affective states the practitioner is meant to manufacture by emotional effort. The classical instruction is an attention-training move: hold a sequence of objects in mind, notice what arises, sustain the orientation through what would otherwise dislodge it. The states that result are described as outcomes of the training, not as feelings to be summoned on demand. The four are also not — though they are sometimes presented as such in the soft-edge Western reception — a programme of generalised positivity. Each has an explicit far enemy that the trained mind is asked to recognise without papering over. The upekkhā limb in particular is not the cool detachment of a witness who has stopped caring; it is the steadiness that allows the previous three to stay in operation when conditions are difficult. Treating the brahmavihāras as a self-help mood-board collapses the curriculum into something less than what the tradition is asking for.
