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

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

### the Chapter which treats of the characteristic features of the different seasons of the year and their influence on health and drugs (Ritucarya-adhyaya)

Sushruta Samhita tr. Bhishagratna, Sutrasthana VI opening · wisdomlib doc122894, his p. 45 · public-domain translation

Bhishagratna expands the chapter title rather than translating the compound; wisdomlib's chapter heading is 'Different seasons of the year'.

### the opportuneness of conduct and food with seasons

Charaka Samhita tr. Avinash Chandra Kaviratna, Lesson VI · archive.org BIUSante_47357 OCR ~line 5399 · public-domain translation

Charaka's chapter is Tasyāśitīya, not titled ṛtucaryā; Kaviratna renders ṛtusātmya as 'opportuneness of conduct and food with seasons'.

### Two months together are called a ŗtu. Ŗtucarya denotes the work or duties which are to be carried out during each Rtu, it includes seasonal food intake, seasonal activities and Seasonal cleansing process(Rtu Anusara śodhana)

WHO International Standard Terminologies on Ayurveda (2022), SV0218 (printed 'ṛtucaryaa') · PDF p.265 (mirror copy) · comparator

WHO includes seasonal śodhana within ṛtucaryā.

## The classical passages

### Charaka Samhita Sutrasthana 6 (Tasyashitiya):Standard 6/3; Kaviratna prints his number 1 after it, checked against the source

> Of him who is acquainted with the opportuneness of conduct and food with seasons, strength and complexion (and happiness and period of life) increase, in consequence of his food, &c., (being taken with propriety).

tr. Avinash Chandra Kaviratna · https://archive.org/download/BIUSante_47357/BIUSante_47357_djvu.txt

The rationale of seasonal regimen (ṛtusātmya). Sanskrit seen at carakasamhitaonline.com: तस्याशिताद्यादाहाराद्बलं वर्णश्च वर्धते। यस्यर्तुसात्म्यं विदितं चेष्टाहारव्यपाश्रयम्॥३॥. '(and happiness and period of life)' is Kaviratna's addition.

### Sushruta Samhita Sutrasthana VI (Ritucharya-adhyaya):Sanskrit verse numbers not established; Bhishagratna pp. 45-50, checked against the source

> Now we shall discuss the Chapter which treats of the characteristic features of the different seasons of the year and their influence on health and drugs (Ritucarya-adhyaya). [...] The fundamental bodily humours such as, wind, bile, etc. augmented and accumulated during the rains, Hemanta and summer, should be checked as soon as they become aggravated... in autumn, spring, or in the forepart of the rainy season.

tr. Kaviraj Kunja Lal Bhishagratna · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122894.html

## The concept record for this term

A term entry answers what the word means. It does not answer whether the thing the word
names is settled, and often it is not. That is what the concept record is for: it sets out
the questions on which the sources disagree about this term, with each position attributed,
and states what is not established.

- [Ritucharya: the classical rationale for seasonal regimen](https://nighantu.ageayurveda.com/concept/ritucharya-rationale/)

## Not to be confused with

- **dinacaryā.** Daily regimen; ṛtucaryā is the seasonal overlay (WHO SV0089 vs SV0218).
- **ṛtusātmya.** The accustomed suitability to a season (Cha.Su.6/3 ṛtusātmyaṃ); ṛtucaryā is the regimen that produces it.
- **ṛtuśodhana.** Seasonal purification is included by WHO within ṛtucaryā but is a distinct Panchakarma practice (cf. PMID 22131733 'Vasantic Vaman').

## Renderings that do not hold

- 'seasonal diet'. Both Charaka 6/3 (ceṣṭāhāra) and WHO include activities/conduct, not food alone.

## Open questions

Recorded rather than resolved.

- Sanskrit verse numbers for the Sushruta Su.6 passages quoted (Bhishagratna prints none).
