## How it is translated, and whether the translation holds

Each rendering is given with the source that uses it. The assessment is ours.

### disorders of manovahasrotas

NAMASTE National Ayurveda Morbidity Codes · NAMC EM (parent), EM-1 'vitiation of manovahasrotas', referenced to Ca.Ni.7/5 · morbidity-code comparator

NAMASTE gives manovaha srotas a code block of its own (EM), which it does NOT give to stanyavaha. But there is NO SAT-B anatomical entry, I searched the complete SAT combined table.

Reproduced unaltered and attributed from the Government of India NAMASTE terminology, which is what that
licence permits, and deliberately absent from the downloadable dataset, which is CC BY 4.0.

### NOT COVERED

WHO International Standard Terminologies on Ayurveda (2022) · absent from ITA-2.5 (body channels) and ITA-5.5 (disorders of vitiated channels) · standards-body comparator · our paraphrase of the source, not its words

I read WHO's full body-channel block and full channel-disorder block and string-searched the extracted text for 'manovaha'/'manovahā': zero occurrences. WHO's channel taxonomy is entirely somatic. This is a substantive omission, not an oversight I can assume away.

### The sense-carrying Srotas (channels) of the body

Kaviraj Kunja Lal Bhishagratna, Sushruta Samhita (1911) · Uttara Tantra, Chapter LXI (Apasmāra), verse 4 region · public-domain translation

This is Bhishagratna's rendering of what the secondary literature calls saṃjñāvaha srotas, the nearest Suśruta analogue. The word 'mind' does not appear; 'sense-carrying' does.

### Channels of transport and transformation of mind and mental factors

carakasamhitaonline.com (CSRTSL) concept article on Manovaha srotas, 2023 · DOI 10.47468/CSNE.2023.e01.s09.157, article title · modern reference work (in copyright; rendering recorded as comparator only)

The same article states plainly that 'The channels carrying functions of mind (manovaha srotas) are not exclusively listed' in the classics, a concession worth recording.

## The classical passages

### Caraka Saṃhitā Nidāna Sthāna 7 (Unmāda Nidāna):4 as printed on the retrieved page (NAMASTE cites 7/5), checked against the source

> ...अभ्युदीर्णा दोषाः प्रकुपिता हृदयमुपसृत्य मनोवहानि स्रोतांस्यावृत्य जनयन्त्युन्मादम्||४||

Sanskrit mūla · https://www.carakasamhitaonline.com/index.php/Unmada_Nidana

THE locus classicus: aggravated doṣas, having approached the hṛdaya, OBSTRUCT the manovaha srotāṃsi and produce unmāda. This is Caraka's only substantive use of the term, and it is pathological, the channel is named in the account of a disease, never enumerated among the thirteen. I quoted the closing clause; the full sentence on the retrieved page is a long etiological list.

### Caraka Saṃhitā Vimāna Sthāna 5:5/7, checked against the source

> वातपित्तश्लेष्मणां पुनः सर्वशरीरचराणां सर्वाणि स्रोतांस्ययनभूतानि, तद्वदतीन्द्रियाणां पुनः सत्त्वादीनां केवलं चेतनावच्छरीरमयनभूतमधिष्ठानभूतं च|

Sanskrit mūla · https://www.carakasamhitaonline.com/index.php/Sroto_Vimana

Decisive for the entry: immediately after listing the thirteen, Caraka says that for the supra-sensory entities beginning with sattva (i.e. mind), it is the ENTIRE sentient body that is the passage and the seat, not any particular srotas. This is why manovaha is not in the list, and it is an argument against localising it.

### Suśruta Saṃhitā Uttara Tantra 61 (Apasmāra-pratiṣedha):4 (Bhishagratna's numbering), checked against the source

> The sense-carrying Srotas (channels) of the body overwhelmed by the concerted action of the deranged Doshas bring in a predominance of Rajas and Tamas (Nescience) causing the patient unconscious and forgetful of all past memories.

tr. Kaviraj Kunja Lal Bhishagratna (1907–1916) · https://archive.org/stream/b24758619_0003/b24758619_0003_djvu.txt

Suśruta's parallel: saṃjñāvaha srotas obstructed by doṣas produces loss of consciousness and memory in apasmāra. I confirmed the chapter is LXI by locating the surrounding chapter headings in the retrieved scan. Like Caraka's, this is a pathological, not a taxonomic, mention.

## Not to be confused with

- **manas (mind).** The faculty, not a channel. Caraka's Vi.5/4 warning applies with special force here: what a srotas is, what it carries, and where it sits are all distinct.
- **saṃjñāvaha srotas / saṃjñāvaha nāḍī.** Suśruta's term (Uttara 61 and, per secondary sources, Uttara 46/7). Bhishagratna renders it 'sense-carrying', i.e. consciousness/sensation rather than mind. Treating the two as identical is an interpretive move, not a translation.
- **rasavaha srotas.** Both are rooted in the hṛdaya; the secondary literature links manovaha specifically to the 'ten dhamanīs' of the heart that Ca.Vi.5/8 assigns to rasavaha. If that link holds they share a substrate.
- **majjāvaha srotas.** Authors who read majjā as nervous tissue end up with two candidate 'neural' channels. Classically majjāvaha is rooted in bone and joints; manovaha in the heart.
- **hṛdaya as anatomical heart vs seat of mind.** The whole localisation of manovaha depends on which hṛdaya is meant, and the texts do not disambiguate.

## Renderings that do not hold

- the nervous system / the brain. Neither text names the head or brain here; both name the hṛdaya. The brain identification is a modern overlay and would contradict the classical root.
- 'the 14th srotas'. manovaha is not in any classical enumeration. Caraka's Vi.5/7 explicitly gives the mind the whole sentient body as its seat instead of a channel.
- 'psychic channels' / 'channels of consciousness' presented as a defined anatomical structure. Both classical mentions are pathological (obstruction producing unmāda / apasmāra). There is no classical description of the channel's root, course or normal function.

## Open questions

Recorded rather than resolved.

- Ca.Ni.7 verse 4 or 5? The two sources I retrieved disagree.
- Is saṃjñāvaha srotas the same channel as manovaha srotas, or a distinct consciousness/sensation channel?
- Does Cakrapāṇi actually identify the heart's ten dhamanīs as manovaha, and if so does that make manovaha a subset of rasavaha?
