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.
1.Seasons, Solstices (Ayana), and Strength (Bala) (Shlokas 1-6)
Definition (Shloka 1):The year is divided into six seasons (Ritus) of two months each, starting with the month of Magha:
- Shishira (Late/Severe Winter)
- Vasanta (Spring)
- Grishma (Summer)
- Varsha (Monsoon/Rainy Season)
- Sharad (Autumn)
- Hemanta (Early Winter)
Details of Seasons and Months:
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 |
Solstices (Ayana) and Effect on Strength (Shlokas 2-6):
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) |
Reasoning:
- Adana Kala: During this period, the Sun and Wind are intensely sharp, hot, and dry. They diminish the Earth’s Saumya (cool and unctuous) qualities, resulting in the gradual decrease of human strength.
- Visarga Kala: Due to the influence of rain, clouds, and cool winds, the Sun’s intensity is subdued. The Moon (Soma) is strong, and the Sun (Ravi) is weak. The dominance of Saumya qualities and the strength of unctuous, sour, salty, and sweet tastes lead to an increase in bodily strength.
2. Status of Strength (Bala) and Digestive Fire (Jatharagni) (Shloka 7)
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) |
Important Note (Shloka 7):
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.
3. Detailed Seasonal Regimen (Ritucharya)
The following tables detail the prescribed Ahara (Diet) and Vihara (Lifestyle/Activities) for the six seasons:
