Sattva, rajas and tamas: the three gunas

Guna means quality, or strand — as in the strand of a rope. The image is exact: three strands twisted together, never found separately, and the character of the rope depends on which one predominates.

What a guna is

The idea comes from Samkhya, the philosophical system that sits behind much of yoga, and it appears throughout the Bhagavad Gita and the Yoga Sutras. The claim is broad: everything in nature — matter, food, thought, mood, a room, an afternoon — is a mixture of three qualities.

Not three types. Three proportions. Nothing is purely one of them, which is why the model describes shifts rather than categories.

The three qualities

Sattva — clarity, lightness, harmony, balance. A sattvic state is calm without being sleepy and alert without being agitated. It is the quality of a mind that can see what is actually in front of it.

Rajas — activity, movement, passion, restlessness. Rajas is heat and drive. It starts things, wants things, and finds stillness uncomfortable. Under its influence you check your phone without deciding to.

Tamas — inertia, heaviness, dullness, darkness. Tamas resists movement. It is the quality of the afternoon after a heavy lunch, of procrastination, of the mind that cannot find the energy to care.

How they show up

Most people recognise their own day in the list immediately.

Waking clear-headed before the alarm, and the first hour passing easily: sattva. Being unable to settle to anything, opening four tabs and finishing none: rajas. Knowing exactly what to do and being unable to begin: tamas.

The three also follow the clock. Early morning is traditionally sattvic, which is why practice is placed there. Midday and afternoon tend to rajas. Late evening and night belong to tamas, which is appropriate when it is time to sleep and unhelpful at nine in the evening when it arrives as scrolling.

Food, sleep and company

Classically, three things move the balance more than anything else: what you eat, how you sleep, and who you spend time with.

Food. Fresh, light, moderately spiced and moderately eaten is sattvic. Very spicy, very salty, stimulating, or eaten in a hurry is rajasic. Heavy, stale, reheated, over-eaten or fermented past pleasantness is tamasic. Sattvic food sets this out in detail, and it is why yoga schools feed students the way they do.

Sleep. Enough is sattvic. Too little produces rajas; too much produces tamas. The Gita is blunt about this in Chapter 6 and it has not dated.

Company and input. What you read, watch and argue about counts as food in this model. A sattvic diet of information is quieter than most people’s.

In your practice

Here is the part that surprises students: the same practice can be any of the three.

A strong sequence done with attention, at a sustainable effort, leaving you clear: sattvic. The same sequence done competitively, chasing a posture, breathing hard and comparing yourself to the next mat: rajasic. Going through the motions half-asleep, or lying in savasana for an hour because getting up is too much effort: tamasic.

Which means the quality of a practice is not determined by its style or its intensity, but by how it is done. This is also why a gentle class is not automatically sattvic and a vigorous one is not automatically rajasic.

Practically, the sequence works like this: movement is the cure for tamas, and stillness is the cure for rajas. If you are heavy and dull, move — sun salutations are the standard answer. If you are agitated, slow down, lengthen the exhale, and let savasana be long.

Beyond the gunas

One correction to a common misreading. The aim is not to become entirely sattvic, and it is certainly not to destroy rajas and tamas. You need rajas to act at all, and tamas to sleep, to rest, and to stop.

The classical goal is more interesting than purification: it is to become free of being pushed around by any of them. The Gita calls that state trigunatita, beyond the three qualities — not a person who is always calm, but one who is no longer at the mercy of whichever strand happens to be pulling.

Sattva is simply the easiest of the three to see clearly from, which is why practice cultivates it first.

Common questions

What are the three gunas?

Sattva, the quality of clarity, harmony and light; rajas, the quality of activity, movement and restlessness; and tamas, the quality of inertia, heaviness and dullness. All three are present in everything in varying proportion.

Is rajas bad?

No. Rajas is the quality that gets anything done — without it there is no movement, no effort and no change. It becomes a problem only when it dominates, producing agitation, craving and an inability to settle. The same is true of tamas, which as rest and sleep is necessary.

What is sattvic food?

Food considered light, fresh and easy to digest: fruit, vegetables, whole grains, legumes, nuts, dairy and mild spices, eaten in moderation and reasonably soon after cooking. It is contrasted with rajasic food, which is stimulating, and tamasic food, which is heavy or stale.

How do you increase sattva?

Regular hours, moderate and fresh food, enough sleep but not excessive sleep, time in nature, steady practice, and care over what you read, watch and who you spend time with. The classical answer is unglamorous and mostly concerns routine.
