c. 1500–500 BCE · Vedic period
The word appears, the practice does not yet
The Rig Veda, the oldest of the Vedic hymns, uses yoga in senses related to yoking,
harnessing and disciplined effort — not to a set of postures. Vedic ritual life was centred on
sacrifice and chant. Breathing and inner concentration were part of priestly practice, but a
distinct “yoga system” is not yet visible in the earliest layers.
c. 800–200 BCE · The early Upanishads
Interiority replaces ritual
Texts such as the Katha and Shvetashvatara Upanishads turn inward. They describe the restraint
of the senses, the stilling of the mind and a kind of meditative absorption, and they begin to
use yoga as a technical term for that inner discipline. This is where yoga becomes a practice
of the self rather than a ritual of the altar.
c. 400 BCE–400 CE · The Bhagavad Gita
Three paths, one conversation
The Gita, an episode within the Mahabharata, presents yoga as a response to moral paralysis.
Krishna teaches three overlapping paths: karma yoga (action without attachment to
reward), bhakti yoga (devotion) and jnana yoga (knowledge). Posture appears,
but briefly — the instruction is to sit steady and moderate in eating and sleeping.
c. 2nd–4th century CE · Patanjali's Yoga Sutras
The classical framework
Patanjali's short, dense sutras define yoga as the stilling of the fluctuations of the mind and
set out eight limbs, from ethical restraint to meditative absorption. The dating is debated;
proposals range from the second century BCE to the fourth century CE. Notably, the sutras give
posture only a single line — “steady and comfortable” — which is a useful corrective to the
assumption that yoga has always meant gymnastics.
c. 500–1500 CE · Tantra and Hatha
The body becomes the instrument
Tantric traditions bring the body, breath and subtle energy into the centre of practice.
The Hatha Yoga Pradipika (fifteenth century), the Gheranda Samhita and the Shiva Samhita
describe postures, breath retention, locks, cleansing techniques and meditation in far more
detail than earlier texts. Many of these practices were austere and were not intended for
general studio consumption.
1893 · Chicago
Yoga goes west, as philosophy first
Swami Vivekananda addresses the Parliament of the World's Religions in Chicago and presents
yoga as rational, universal spirituality. His Raja Yoga (1896) introduces the eight
limbs to an English-speaking audience. Notably, this first wave is almost entirely mental and
philosophical — postural yoga was still to come.
1920s–1950s · Mysore
The modern postural synthesis
T. Krishnamacharya teaches in Mysore, training students who will define the century:
B. K. S. Iyengar, K. Pattabhi Jois and his own son T. K. V. Desikachar. Their methods differ
sharply — precision and props, fixed athletic series, individualised therapeutic practice —
but all three produce the postural systems that spread globally.
1960s–1980s · Global boom
Studios, styles and the counterculture
Yoga travels with the counterculture, then with fitness culture. Bikram Choudhury's heated
sequence arrives in the 1970s; Power yoga emerges in the 1990s as an athletic, non-fixed
descendant of Ashtanga; Yin yoga is formulated in the late twentieth century from separate
influences. The number of named styles multiplies, and with it the confusion this page exists
to reduce.
2000s–today
Mainstream, online, and under study
Yoga becomes a mass practice and a research subject. Studios, retreats and streaming classes
reach audiences the twentieth-century teachers could not have imagined. At the same time,
scholars, practitioners and Indian critics continue to debate appropriation, commercialisation
and the gap between the tradition's aims and the fitness language used to sell it.
