What is Mauna?
Mauna is the Sanskrit term for a deliberate, time-bound vow of silence taken as a contemplative discipline. It appears across Hindu, Buddhist, Christian, and Sufi traditions under different names but the same essential form.
The word comes from the root man- (to think). The simplest form is vāk-mauna, silence of speech only, with thought and gesture still in operation. The more demanding forms are kāṣṭha-mauna, in which the discursive layer of mind is also stilled, and sūṣupti-mauna, the silence of the deep-sleep state, which can only be recognised, not engineered. In classical Hindu sources, mauna is one of the disciplines a sannyāsin takes on entering renunciate life. In brahmacarya training, the eleventh and twelfth lunar phases and the full-moon and new-moon days were reserved for an attenuated form. The instruction in either case is the same: stopping outer speech surfaces the inner discursive movement for inspection.
What mauna is not
Mauna is not the absence of speech through social awkwardness or an inability to find words. The technical sense of the term reserves it for what is deliberate and taken on. Silence outside a wider *sādhana* is, in the classical view, at best neutral and at worst a way of cultivating inner conceit. It is also not the same as the silence the contemplative traditions point to as an awareness-recognition. Mauna is the disciplined refraining that opens room for that recognition. The two are not identical: the recognition can happen in speech, and can fail to happen in mauna. The technical literature is careful not to collapse the discipline into what it serves.
The cross-tradition parallels are real but not identical. Ariya tuṇhī-bhāva, noble silence in the Pāli vocabulary, is defined by Sāriputta as the second *jhāna*, the meditative state in which discursive thought falls away while attention stays lucid. Hesychia in Christian hesychasm names the interior stillness the Greek Fathers cultivate. Al-ṣamt in the Sufi vocabulary is the outer-discipline component of a wider interior practice. All three traditions arrived at a structurally identical discipline independently.
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. It also provides the silent ground that *dhāraṇā*, *dhyāna* and *samādhi* presuppose. The Theravāda residential retreat preserves the discipline in practice: 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.
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, a 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. 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 treated as a load-bearing component of the curriculum's reported outcomes. 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 its interval.
