Vāta, pitta, kapha, the three doṣas

The word and the verse

Doṣa (दोष) first means a fault, a defect. Monier-Williams adds the medical sense: a "morbid element", applied especially to the three humours of the body and then to the humours themselves. The name says something important: a doṣa is what can go wrong. In balance it is a function of life; out of balance it is the beginning of disease.

Vāgbhaṭa, whose Aṣṭāṅgahṛdaya summarises classical Āyurveda, states them in half a line:

वायुः पित्तं कफश्चेति त्रयो दोषाः समासतः ।

vāyuḥ pittaṃ kaphaś ceti trayo doṣāḥ samāsataḥ |

Wind, bile and phlegm: these, in brief, are the three doṣas.

The next verse gives their double nature: "deranged or not deranged, they destroy the body or sustain it" (1.7). And a little further, the whole medical theory in one line: "disease is the imbalance of the doṣas; health is their balance" (rogas tu doṣa-vaiṣamyaṃ doṣa-sāmyam arogatā, 1.20).

The three doṣas and their qualities

The English words wind, bile and phlegm are old and misleading. Today's teachers prefer to describe what each doṣa does: vāta moves, pitta transforms, kapha holds together. Vāgbhaṭa defines them by their qualities (guṇa):

तत्र रूक्षो लघुः शीतः खरः सूक्ष्मश्चलोऽनिलः । पित्तं सस्नेहतीक्ष्णोष्णं लघु विस्रं सरं द्रवम् ॥ स्निग्धः शीतो गुरुर्मन्दः श्लक्ष्णो मृत्स्नः स्थिरः कफः ।

tatra rūkṣo laghuḥ śītaḥ kharaḥ sūkṣmaś calo 'nilaḥ / pittaṃ sasneha-tīkṣṇoṣṇaṃ laghu visraṃ saraṃ dravam || snigdhaḥ śīto gurur mandaḥ ślakṣṇo mṛtsnaḥ sthiraḥ kaphaḥ |

Of these, wind is dry, light, cold, rough, subtle and mobile. Bile is slightly oily, sharp, hot, light, of raw smell, flowing and liquid. Phlegm is oily, cold, heavy, slow, smooth, slimy and stable.

Modern presentations also link each doṣa to two of the five elements: vāta to air and space, pitta to fire and water, kapha to water and earth. The chapters of Vāgbhaṭa and Caraka quoted on this page do not set it out in that form: Caraka uses the five elements above all to explain the six tastes (Caraka Saṃhitā, Sūtrasthāna 26.40), and Vāgbhaṭa notes only that pitta, though made of all five elements, is called "fire" because the fiery quality predominates in it (12.10-12.11).

The five forms of each doṣa

"What are the 5 doshas?" is a common question. There are three, but each has five forms. The twelfth chapter of the Sūtrasthāna names them:

• Five winds: prāṇa in the head, udāna in the chest, vyāna in the heart moving through the whole body, samāna near the digestive fire, apāna in the pelvic region (12.4-12.9). These are the same five names yoga gives to the currents of prāṇa.
• Five pittas: pācaka (digesting), rañjaka (colouring), sādhaka (in the heart), ālocaka (in the eyes), bhrājaka (in the skin) (12.10-12.14).
• Five kaphas: avalambaka (supporting, in the chest), kledaka (moistening food), bodhaka (on the tongue, perceiving taste), tarpaka (in the head), śleṣaka (in the joints) (12.15-12.18).

Constitution and the rule of opposites

Each person is born with a characteristic proportion of the doṣas, the prakṛti (प्रकृति). Vāgbhaṭa ranks the single-doṣa constitutions vāta, pitta and kapha as poor, middling and best, the balanced one as best of all, and those dominated by two doṣas as the least favourable (1.10). Modern presentations, more diplomatic, simply describe "vāta types", "pitta types" and "kapha types".

The working principle comes next:

वृद्धिः समानैः सर्वेषां विपरीतैर्विपर्ययः ।

vṛddhiḥ samānaiḥ sarveṣāṃ viparītair viparyayaḥ |

All things increase through what is similar, and decrease through what is opposite.

Cold, dry, mobile vāta is calmed by what is warm, oily and steady; hot, sharp pitta by what is cool and mild; heavy, slow kapha by what is light and active. This single rule is the basis of everything said about "yoga for your dosha".

Yoga by doṣa: a tradition, not a prescription

The classical yoga texts do not prescribe postures by doṣa; the idea is a modern synthesis of the two traditions, built on the rule of opposites. It is a useful lens for choosing how to practise, not a medical method, and no study has shown that matching practice to a doṣa type gives better results.

Vāgbhaṭa also reminds us that the doṣas follow the clock: they predominate at the end, middle and beginning of life, of the day, of the night and of digestion (1.8). Hence the modern advice to practise vigorously in the kapha hours of the morning and to calm the evening.

Are the doṣas real?

They are a model, more than two thousand years old, for describing temperament, digestion and illness. They are not entities of modern physiology, and dosha questionnaires are not medical tests. Research on the subject is young: in 2015, an Indian team compared the genomes of 262 men classified into the three constitution types (selected after screening 3,416 people) and reported 52 genetic variants that differed between the groups. It is an exploratory study, in men only, that does not show the doṣas cause anything or that dosha-based treatment works.

Our sister site Guide Ayurveda goes further, with a page for each doṣa (vata, pitta, kapha), a free dosha quiz, an honest review of what studies show about doshas and a guide to yoga by dosha.

On this site, the sattvic diet page shows the other triad, the three guṇa of the mind, which Vāgbhaṭa calls the doṣas of the mind (1.21). Our book The Sattvic Kitchen explains the six tastes and the three doṣas without dogma, with 42 simple vegetarian recipes.
