A comprehensive English explanation of the 'Ritucharya' (Seasonal Regimen) chapter from the classical Ayurvedic text, Ashtanga Hridaya Samhita, detailing diet and lifestyle for all six seasons.
Tue, Nov 25, 2025This guide provides a detailed, shloka-based (verse-based) breakdown of the two Solstices (Ayana) and the specific regimens (Ahara and Vihara) for Hemanta, Shishira, Vasanta, Grishma, Varsha, and Sharad seasons, as per classical Ayurvedic principles.
This chapter addresses ‘Ritucharya’ (Seasonal Regimen), which prescribes specific dietary and lifestyle practices in accordance with the changing seasons to maintain optimal health and bodily strength.
Definition (Shloka 1):The year is divided into six seasons (Ritus) of two months each, starting with the month of Magha:
Each season lasts for two months.
| Season (Ritu) | Hindu Calendar Months | Gregorian Calendar Approx. |
|---|---|---|
| Shishira (Severe Cold) | Magha, Phalguna | Mid-January to Mid-March |
| Vasanta (Spring) | Chaitra, Vaishakha | Mid-March to Mid-May |
| Grishma (Summer) | Jyeshtha, Ashadha | Mid-May to Mid-July |
| Varsha (Monsoon/Rainy) | Shravana, Bhadrapada | Mid-July to Mid-September |
| Sharad (Autumn) | Ashvina, Kartika | Mid-September to Mid-November |
| Hemanta (Early Winter) | Margashirsha, Pausha | Mid-November to Mid-January |
The six seasons are divided into two Ayanas (Solstices – Uttarayana and Dakshinayana), which directly influence the body’s strength.
| Name of Ayana | Seasons Included | Nature of Influence | Effect on Strength (Bala) | Dominant Tastes (Prabala Rasa) |
|---|---|---|---|---|
| Uttarayana (Adana Kala) (Northern Solstice/Period of Taking Away) | Shishira, Vasanta, Grishma | Agneya (Fiery/Harsh) | Decrease in Strength (Bala gradually declines) | Bitter (Tikta), Astringent (Kashaya), Pungent (Katu) |
| Dakshinayana (Visarga Kala) (Southern Solstice/Period of Giving Forth) | Varsha, Sharad, Hemanta | Saumya (Cooling/Gentle) | Increase in Strength (Bala is restored) | Sour (Amla), Salty (Lavana), Sweet (Madhura) |
The body’s strength and digestive fire are altered according to the seasons:
| Season | Strength (Bala) | Digestive Fire (Jatharagni - Anala) |
|---|---|---|
| Hemanta (Cold Season) | Superior (Highest) | Strong (Prabala) |
| Varsha (Rainy Season) | Inferior (Lowest) | Weak (Manda) |
| Sharad, Vasanta, Grishma | Moderate (Madhyama) | Moderate (Madhyama) |
Due to the intense cold (Hemanta), the body’s internal heat (Ushma) is obstructed (confined), leading to a very strong digestive fire. If this fire does not receive sufficient fuel (food), it is provoked by Vayu (Vata) and begins to digest the body’s own Dhatus (tissues). Therefore, consuming adequate food is essential.
The following tables detail the prescribed Ahara (Diet) and Vihara (Lifestyle/Activities) for the six seasons:
