What the practice consists of
Mauna — Sanskrit, from the verbal root man- (to think) — names the deliberate sustained refraining from speech as a contemplative discipline. The practice is concrete: a period is stated, the practitioner stops speaking, and the cessation is held with whatever quality of attention is available. The simplest form is vāk-mauna — silence of speech only, with thought and gesture still in operation; the more demanding forms add kāṣṭha-mauna (silence of thought as well, the discursive layer of mind allowed to settle) and sūṣupti-mauna (the silence of the deep-sleep state, available only as a recognition, not as something that can be engineered). The classical Hindu vocabulary treats mauna as one of the disciplines a sannyāsin takes on entering the renunciate stage of life, and the householder-traditions of brahmacarya training reserved specified days — the eleventh and twelfth lunar phases, the full-moon and new-moon — for an attenuated form. The instruction in either case is the same: the discursive function of mind operates most visibly because of the speech function, and stopping the outer flow surfaces the inner one for inspection.
Where it sits in the wider curriculum
Mauna is not a path in its own right; it is a discipline taken on inside one. In the yoga tradition it operates as a refinement of the yama of satya (truthfulness) — speech that does not happen cannot be untruthful — and it provides the silent ground that the inner limbs of *dhāraṇā*, *dhyāna* and *samādhi* presuppose. In the Pāli vocabulary the structurally analogous condition is ariya tuṇhī-bhāva — noble silence — which the Buddha's senior disciple Sāriputta defines as the second *jhāna*, the meditative state in which discursive thought has fallen away while attention remains lucid. The Theravāda residential retreat preserves the discipline as the operative structure of the format: a vipassanā course at the Insight Meditation Society or in the Goenka tradition is held in functional mauna from the opening evening to the last morning, with speech permitted only in the brief teacher interview. The Christian hesychasm tradition organises its practice around hesychia — the quiet or stillness the Greek Fathers describe in language that maps closely onto the Sanskrit mauna. The Sufi vocabulary's al-ṣamt names the outer-discipline component of a wider interior practice. The convergence is the load-bearing observation across the traditions: a structurally identical discipline appears in lineages that did not borrow it from one another, and the report from inside the practice is recognisably the same.
Where it appears in the index
The most consequential modern carriers of the practice are the residential retreat formats. The joint Insight Meditation course Goldstein and Salzberg teach is held in functional mauna across the residential days — the format imported from the Burmese Mahāsi tradition and stabilised in English from 1976 onward. The Plum Village teaching from Br. Troi Duc Niem carries the discipline in the Mahāyāna idiom that Thich Nhat Hanh formalised as noble silence — observed across mornings, meals and walking periods, with speaking suspended for the duration. Jon Kabat-Zinn's MBSR curriculum carries a secularised version into the eight-week clinical programme: the day-long retreat at week six is held in silence, and the discipline is treated as a load-bearing component of the curriculum's reported outcomes rather than as an optional refinement. The Christian counterpart in the index is the Centering Prayer Course, in which Thomas Keating's adapted apophatic discipline is held within sustained interior hesychia. Rupert Spira's longer-form retreat teaching is structured around long silent sittings between dialogue periods, with the silence treated as the operative content of the retreat rather than as the interval between content.
What it isn't
Mauna is not the absence of speech as social embarrassment or as the failure to find words; the technical sense of the term reserves it for the deliberate, taken-on, time-bound practice. It is not a vow of speechlessness for its own sake — the classical instruction is unambiguous that silence outside a wider *sādhana* is at best neutral and at worst a way of cultivating inner conceit. And it is not the same as the silence the contemplative traditions point at as the recognition of awareness itself — mauna is the disciplined refraining that opens room for that recognition, and the two are not identical. The recognition the practice prepares for can happen in speech and can fail to happen in mauna; the technical literature is careful about not collapsing the discipline into what the discipline serves.
