Written by Joseph Berridge, Founder of Joga Yoga
The trigunas, or three gunas, are sattva (clarity and balance), rajas (activity and passion) and tamas (inertia and heaviness). The idea comes from Samkhya philosophy, which describes all of nature as a mix of these three qualities, and it runs through yoga, the Bhagavad Gita and Ayurveda.
Where do the three gunas come from?
The gunas are a core idea in Samkhya, one of the oldest schools of Indian philosophy. Samkhya describes the world as made of two principles: purusha, pure consciousness, and prakriti, nature or matter. Prakriti is made of the three gunas, and everything in the material world, including the body and mind, is some mix of them. The Wikipedia entry on guna gives a fuller history of the concept.
Yoga philosophy took this model from Samkhya. Patanjali’s Yoga Sutras use it, and the Bhagavad Gita, which is often wrongly given as the origin, explains the gunas in detail. Chapter 14 is devoted to them, chapter 17 applies them to faith, food and worship, and chapter 18 applies them to action and knowledge.
The word guna means “quality” or “strand,” like the strands twisted together to make a rope. All three are always present. What changes is which one is strongest at a given time.
Sattva, rajas and tamas compared
| Sattva | Rajas | Tamas | |
|---|---|---|---|
| Core quality | Clarity, balance, light | Activity, passion, movement | Inertia, heaviness, stability |
| In the mind | Calm, focused, content | Restless, ambitious, driven by desire | Dull, sluggish, confused |
| Useful side | Insight and peace | Energy to act and get things done | Rest, sleep and grounding |
| When it is excessive | Rarely a problem, though attachment to calm is still attachment | Stress, agitation, burnout | Lethargy, procrastination, low mood |
| Food in the Gita | Fresh, light, nourishing | Very spicy, salty or stimulating | Stale, overcooked or heavily processed |
None of the three is simply bad. Rajas gets you out of bed and tamas lets you sleep. Yoga aims for sattva to lead, with rajas and tamas in their useful roles.
What the gunas mean in daily life
The gunas are useful as a way of noticing your own state. A morning of scattered tasks and too much coffee is rajasic. An afternoon on the sofa after a heavy lunch is tamasic. A quiet walk with a clear head is sattvic.
Seen this way, the gunas explain why the same person can feel very different from one day to the next. They also explain why yoga gives so much attention to food, sleep, company and routine, not just to poses.
The gunas in yoga practice
Most yoga practice can be read as a way to reduce excess rajas and tamas and let sattva lead.
- Asana. A dynamic practice can lift tamas when you feel heavy, and a slow, steady practice can calm rajas when you feel agitated. Our explainer on what asana yoga is covers the basics.
- Pranayama. Slow breathing settles rajas, while energising breaths can shake off tamas. Our pranayama guide explains the techniques.
- Meditation. Sitting practice is the most direct way to cultivate sattva. See our guide to yoga meditation.
- Ethics. The yamas and niyamas work on the same goal from the side of behaviour.
Food is the clearest everyday example. The traditional yoga diet sorts food into sattvic, rajasic and tamasic groups, and our guide to sattvic food explains how that works on the plate.
The gunas in Ayurveda
Ayurveda uses the same three gunas to describe the mind. Sattva is the balanced, healthy state of the mind, while rajas and tamas are treated as the mind’s two doshas, or sources of imbalance. This is separate from the three body doshas, vata, pitta and kapha, which Ayurveda uses to describe physical constitution.
The idea of sattvic, rajasic and tamasic personality types has also been studied in modern psychology research, often under the name triguna theory of personality.
How to cultivate sattva
You do not need to change your whole life to shift the balance. Small, regular habits matter most:
- Keep a steady routine for sleep and meals.
- Eat mostly fresh, simple food and avoid overeating.
- Practise yoga, breathwork or meditation regularly, even for a few minutes.
- Spend time outdoors and limit constant stimulation from screens.
- Notice which guna is leading before you react, and adjust what you do next.

Frequently asked questions
What are the three gunas?
The three gunas are sattva (clarity and balance), rajas (activity and passion) and tamas (inertia and heaviness). In Samkhya and yoga philosophy, they are the qualities that make up all of nature, including the body and mind.
What does the Bhagavad Gita say about the three gunas?
The Bhagavad Gita explains the gunas mainly in chapter 14, where Krishna describes how each one binds a person. Chapters 17 and 18 apply the gunas to faith, food, action and knowledge.
Which guna is best?
Sattva is the one yoga aims to cultivate, but all three are needed. Rajas gives energy to act and tamas allows rest. Problems come from too much rajas or tamas, not from their presence.
Are the trigunas fixed or can they change?
They change all the time. The balance shifts with food, sleep, activity and state of mind, and yoga, breathwork and meditation are traditional ways to move it toward sattva.
How can I cultivate sattva in my life?
Keep a regular routine, eat fresh and simple food, practise yoga or meditation regularly, and limit overstimulation. Small, consistent habits matter more than big changes.
