The 20 gunas of Ayurveda (the gurvadi gunas) are ten pairs of opposite qualities — such as heavy-light (guru-laghu), cold-hot (shita-ushna) and oily-dry (snigdha-ruksha). Ayurveda describes every food, every medicinal substance, every season and every state of the body in terms of these qualities. The core rule is simple: like increases like; opposites bring balance.

Think of what grandmothers used to say: “It’s cold — have jaggery and sesame,” “With fever, eat khichdi, not puris,” “Don’t drink cold water, it’ll catch your throat.” They never used the word “guna”, yet they were applying exactly this science: warm, unctuous sesame against the cold, dry winter; light khichdi, not heavy puris, for a weakened digestive fire.

In Issue 010 we saw that warm water, being hot and light, suits Vata and Kapha but calls for care in Pitta — that whole discussion was in the language of gunas. And in Issue 007 and Issue 008 we explored the five elements — the gunas are the signatures those elements leave behind.

गुरुमन्दहिमस्निग्धश्लक्ष्णसान्द्रमृदुस्थिराः।
गुणाः ससूक्ष्मविशदा विंशतिः सविपर्ययाः॥

— Ashtanga Hridaya, Sutrasthana 1

Meaning: Heavy, dull, cold, unctuous, smooth, dense, soft, stable, subtle and clear — these ten qualities, together with their ten opposites, make up the twenty gunas.

1. What Ayurveda says — the ten pairs at a glance

Examples are for illustration only. A single substance carries many qualities at once, and cooking method, quantity and combination all change them.

The root principle — samanya and vishesha: Charaka Samhita teaches that similarity (samanya) always causes increase and difference (vishesha) causes decrease. So if dryness has built up in the body, more dry food will add to it; something unctuous — a little ghee or sesame — will balance it. The whole of Ayurvedic diet and lifestyle advice stands on this single logic.

2. Gunas and the three doshas

Ayurveda defines the doshas themselves through gunas (in the spirit of Ashtanga Hridaya, Sutrasthana 1):

• 🌬️ Vata: dry, light, cold, rough, subtle, mobile — hence dry skin, cold hands and feet, gas, restlessness, irregularity.
• 🔥 Pitta: slightly oily, sharp, hot, light, flowing, liquid — hence strong hunger, burning, sweating, a sharp intellect, quick temper.
• 🌿 Kapha: oily, cold, heavy, dull, smooth, stable, sticky — hence stability, patience, a sturdy body, but in excess heaviness, lethargy and mucus.

Now it makes sense why cold, dry winds raise Vata, why spicy fried food raises Pitta, and why daytime sleep and sweet, heavy food raise Kapha — like increases like. A full introduction to Vata, Pitta and Kapha comes in Issue 015.

3. Through the lens of modern science — no mystery here

In today’s language, the gunas can be understood as the physical and physiological properties of a substance — temperature, density, oiliness, moisture, texture, viscosity.

• Heavy-light: meals rich in fat and protein leave the stomach more slowly (slower gastric emptying) — which is why a heavy meal keeps you full and sluggish for longer.
• Oily-dry: low-humidity winter air draws moisture from the skin; adequate water and a little healthy fat support skin and bowels — “unctuous against dry”.
• Cold-hot: warm drinks soothe the throat; cooling foods ease a burning feeling — everyday experience.
• Stable-mobile: regular routines and sleep times keep the body clock (circadian rhythm) steady; a very irregular life increases the “mobile” quality.

Note that Ayurvedic “cold/hot” is not always thermometer temperature — it is the effect on the body. A mango from the fridge, for example, is still considered heating in Ayurveda. Modern research has not yet verified each of these concepts individually; treat them as a tool for self-observation and for working with a qualified vaidya.

4. The 20 gunas on your plate — balancing with opposites

• Heavy stomach, sluggish (heaviness up): make the next meal light — moong, khichdi, vegetable soup; eat only when truly hungry.
• Cracked skin and lips, constipation (dryness up): a little ghee or sesame oil in food, warm cooked meals; fewer dry snacks.
• Burning, sour belching (heat and sharpness up): less chilli, fried and sour food; cooling, soft foods such as bottle gourd, ash gourd, coconut — with a qualified vaidya’s advice.
• Mucus, heaviness (stickiness and heaviness up): less curd, sweets and cold foods; warm, light, mildly sharp food such as a dry-ginger soup.
• Restless mind, broken sleep (mobility up): fixed meal and sleep times, a warm, unctuous dinner, less screen time — invite the stable quality.

Cooking changes gunas too: roasting adds lightness, tempering in ghee adds unctuousness, boiling adds softness. This is why Issue 008 spoke of “balancing the five elements on your plate”.

5. The seven prakritis — which qualities to watch?

Please don’t decide your prakriti from this table — a qualified vaidya determines it through examination.

6. Who should be especially careful?

• Avoid self-diagnosis: spotting two or three signs, deciding “my Vata is high” and drastically changing your diet is not wise.
• People with diabetes, heart disease, kidney disease or high cholesterol: “increase unctuousness” does not mean adding lots of ghee and oil; your doctor’s dietary advice comes first.
• Pregnant women, young children, the elderly: sharp, heating items (strong spices, raw garlic and the like) only with a qualified vaidya’s advice.
• Anyone on medication: don’t start any herb or remedy on your own because of its “qualities”; dose and combination are for the vaidya to decide.
• See a doctor promptly if you have: high fever, chest pain, breathlessness, persistent vomiting or diarrhoea, blood in stool, or sudden weight loss.

7. In this season — the qualities of Hemanta

In November’s Hemanta (early winter) the outside environment is cold and dry. According to Ayurveda, digestive fire is usually strong at this time, so somewhat heavy and unctuous food — jaggery, sesame, ghee, wheat, seasonal vegetables — is digested well. Cold, stale, dry food and long gaps without eating can aggravate Vata.

Practical cues: warm water (hot), sesame-oil self-massage (unctuous), regular meal and sleep times (stable). For more, read Issue 006 — What to eat in winter.

🩺 8. Nadi Pariksha — qualities under the fingertips

In Nadi Pariksha, the vaidya is really sensing gunas. A pulse that feels fast, irregular, thin and dry (mobile, dry, subtle) points towards Vata; one that feels jumping, warm and intense (hot, sharp) towards Pitta; one that feels slow, deep, full and steady (dull, heavy, stable) towards Kapha. Tradition compares these to the movement of a snake, a frog and a swan. Speed • rhythm • strength • depth • temperature — all of it is the language of gunas.

Across Nadi Vaidya Dr. Ajit Singh Yadav’s 36+ years of clinical experience, diet and lifestyle guidance has always been based on the qualities felt in the pulse. The Nadi Vaidya family has experience consulting with the film industry, royal families, leading business families and international patients, and Nadi Vaidyas trained at Nadi Vaidya Gurukul now serve in almost every state of India.

“You don’t just touch the pulse — you have to connect with it.”

Read the basics of pulse reading in Issue 002, and if you’d like to learn this art yourself, see the Nadi Pariksha course.

Nadi Pariksha is a traditional Ayurvedic holistic assessment method; it is not a substitute for lab tests or modern investigations.

🏡 9. Today’s practical experiment — a seven-day guna diary

• Day 1: Describe today’s meals in gunas — what was heavy, what was light? How did you feel two hours later?
• Day 2: Notice cold vs hot — how does your body feel after cold foods versus warm ones?
• Day 3: Oily vs dry — note the state of your skin, lips and stools.
• Day 4: Stable vs mobile — note your sleep and wake times and any restlessness of mind.
• Day 5: Pick the quality that seems most excessive and adopt one simple opposite (e.g. dryness → a little ghee with meals).
• Day 6: Try to understand your family’s home remedies in the language of gunas.
• Day 7: Review the week — which quality seems most “sensitive” for you? Show this diary to your vaidya.

This exercise is not a diagnosis — only self-observation. If you notice any unusual symptom, consult a qualified vaidya or doctor.

Frequently asked questions

What are the 20 gunas of Ayurveda?
Ten pairs: heavy-light, dull-sharp, cold-hot, oily-dry, smooth-rough, dense-liquid, soft-hard, stable-mobile, subtle-gross and clear-sticky. They are also called the gurvadi gunas.

What is the most important rule of the gunas?
Like increases like; opposites decrease. Food and habits with the opposite quality to whatever is in excess bring balance.

Does “hot” (ushna) always mean high temperature?
Not always. In Ayurveda, hot and cold also describe the effect on the body — even something served cold can have a heating effect.

Can I work out my prakriti from the gunas myself?
Understanding gunas gives you a way to observe your body, but prakriti and current dosha state are determined by a qualified vaidya through examination.

How are gunas felt in the pulse?
An experienced vaidya senses qualities such as mobile-stable, heavy-light and hot-cold in the pulse’s speed, rhythm, strength, depth and temperature. It is a skill built through practice — see the Nadi Pariksha course to learn it.

An easy way to remember —

⚖️ Heavy-light — feeling heavy? eat light
🌡️ Cold-hot — warmth against the cold
💧 Oily-dry — a little unctuousness for dryness
🧘 Stable-mobile — routine for restlessness
🔁 Like increases, opposite balances
