The four foundations
Satipaṭṭhāna is the Pāli compound of sati — attention, recollectedness, the cognitive faculty that holds an object in mind without losing it — and paṭṭhāna — establishment, application, placing. The Satipaṭṭhāna Sutta of the Majjhima Nikāya (sutta 10), repeated almost verbatim as the longer Mahāsatipaṭṭhāna Sutta of the Dīgha Nikāya (sutta 22), is the Buddha's most detailed surviving instruction on what sati is for and how to train it. The sutta opens with what the Theravāda tradition has read as the operative claim: ekāyano ayaṃ bhikkhave maggo — this is the one-way path — for the purification of beings, the overcoming of sorrow, the realisation of liberation. The path described under that prefix has four foundations. The first, kāyānupassanā, attends to the body — to the breath in its long and short forms, to bodily posture, to clear comprehension of action, to anatomical analysis, to the four elements, and to the cemetery contemplations. The second, vedanānupassanā, attends to vedanā — the immediate felt tone of pleasant, unpleasant or neutral that arises with every sense-event before the mind has named what is there. The third, cittānupassanā, attends to the state of mind itself — its concentration or distraction, its colouration by greed, hatred or delusion. The fourth, dhammānupassanā, attends to the categorical structure of experience the Buddhist analysis maps: the five hindrances, the five aggregates, the six sense-bases, the seven factors of awakening, the four noble truths. The instruction in each domain is the same: notice what is here, notice that it is impermanent, do not cling, do not push away.
The Burmese vipassanā revival and its Western descendants
The Satipaṭṭhāna Sutta is the canonical source the twentieth-century Burmese vipassanā revival was reconstructing from. Ledi Sayadaw (1846–1923) re-centred the sutta in lay practice in late-colonial Burma; Mingun Jetavan Sayadaw refined the working method through long retreat; and Mahāsi Sayādaw's seven-year retreat in the late 1930s produced the noting technique — rising, falling, thinking, hearing, pain — that became the operational reading of the sutta's first two foundations, kāya and vedanā, in close-grained moment-to-moment register. The U Ba Khin and S. N. Goenka householder lineages descend from the same textual base and apply a body-scan method to the same vedanā foundation. The Burmese reading is the one that crossed the Pacific: when Joseph Goldstein, Sharon Salzberg and Jack Kornfield co-founded the Insight Meditation Society in Massachusetts in 1976, the operative manual they trained American students into was the Satipaṭṭhāna Sutta in the form Burmese teachers had stabilised it. The IMS curriculum is in the index in the closest readings. Joseph Goldstein's *Mindfulness* is a chapter-length commentary on the sutta built on forty years of retreat teaching — the book reads as a sutta reading from inside the practice it instructs. Goldstein and Salzberg's *Insight Meditation* audio course carries the same material in long-form guided sits. Tara Brach and Jack Kornfield's *Power of Awareness* walks the four foundations across a multi-week sequence in the affective register the IMS line has been associated with. Jon Kabat-Zinn's *Full Catastrophe Living* is the secular clinical descendant: the body scan and the noting practice the eight-week MBSR programme prescribes are the first two foundations of satipaṭṭhāna with the Pāli vocabulary set aside.
The sutta beyond the Theravāda reading
The Satipaṭṭhāna Sutta is not exclusively Theravāda property, although the Pāli canon's preservation and the Burmese revival have given the school the strongest contemporary claim on it. The same sutta appears in the Chinese Madhyama Āgama in a parallel translation that the Sarvāstivāda school transmitted, and a Mahāyāna commentarial tradition reads its content through the prajñāpāramitā lens — the four foundations function the same way in the analysis but are not treated as the terminus of the path. Thich Nhat Hanh on emptiness, signlessness and aimlessness reads the four foundations through the prajñāpāramitā recension, with the emptiness the Mahāyāna tradition reads into the dhammas foundation foregrounded; the Plum Village teaching carries the same content in pastoral register. The four foundations are also operationally what the *Visuddhimagga*'s insight section systematises, what the *Ānāpānasati Sutta* — the mindfulness of breathing discourse — works through the breath as a single thread, and what the contemporary clinical mindfulness movement has extracted to a secular setting. Different lineages have read the sutta differently; the document itself has not changed.
What it isn't
Satipaṭṭhāna is not a relaxation practice. The four foundations are an analytic dissection of experience engineered to surface the three marks — anicca, dukkha and anattā — under direct observation rather than as doctrine, and the calm the practice produces is, in the sutta's own terms, a side-effect of the seeing rather than its goal. It is also not a method invented by twentieth-century Burmese teachers; the lineage reconstructed the working sutta-reading from canonical sources that had been preserved across the Theravāda's continuous textual transmission, and the operational claim — that disciplined attention to body, vedanā, mind-state and dhammas in that order is what the path runs on — is the same claim the Buddha is recorded as having made in the sutta. And it is not exhausted by mindfulness as the contemporary clinical literature uses the word: the secular extraction has kept the first two foundations, set aside the third and fourth, and produced a clinically useful technique that is not, on the sutta's own terms, the complete curriculum.
