The claim that the physical practice being taught today is five thousand years old and unchanged is repeated constantly and is not well supported. The real history is more interesting, and telling it honestly does not diminish the practice.
What the old texts actually contain
The word appears in Indian texts going back a very long way, including the Vedas and the Upanishads, but what it refers to there is largely a contemplative and philosophical discipline rather than a system of physical postures.
Patanjali's Yoga Sutras, usually placed somewhere in the early centuries of the common era, is the foundational text of classical yoga. It has remarkably little to say about posture. Essentially that the seat should be steady and comfortable. It names no postures at all.
Later hatha texts, from roughly the eleventh century onward, do describe postures, along with breath practices and cleansing techniques. But the numbers are small. The Hatha Yoga Pradipika, a fifteenth-century text, describes around fifteen, most of them seated or lying. The much later Gheranda Samhita lists thirty-two.
There is no historical text describing the large, flowing, standing-posture-heavy sequences that fill a modern class.
What changed in the twentieth century
A great deal, and in a relatively short period.
Indian physical culture in the late nineteenth and early twentieth centuries was in active conversation with European gymnastics, Scandinavian physical training systems, wrestling traditions and military exercise programmes then circulating in India. These were not marginal influences.
Tirumalai Krishnamacharya, teaching in Mysore from the 1930s, is central to the story. His students included B.K.S. Iyengar, Pattabhi Jois and Indra Devi, and between them they shaped most of what is now practised globally. The sequences taught at the Mysore palace were dynamic, athletic, and taught largely to boys and young men, a context quite different from the one the practice now occupies.
Many standing postures that feel foundational today appear to have taken their current form during this period. The sun salutation, in the form widely practised, has a documented history considerably shorter than usually assumed.
Why this matters
Three reasons, and none of them is debunking.
It makes the practice more honest. A teacher who says a posture is ancient when it is not is making a claim they cannot support, and that erodes trust in everything else they say.
It removes a bad argument. "This is correct because it is ancient" is not a good reason for anything. The practice can be evaluated on whether it does what it claims, which is a stronger footing.
It credits the actual innovators. The people who shaped modern practice were working in the twentieth century, thoughtfully and inventively. Attributing their work to anonymous antiquity is a strange way to honour a tradition.
What is genuinely old
The philosophical framework, the ethical material, the breath and concentration practices, and the underlying project of using body and breath to work with the mind. Those have deep roots and real continuity.
So the honest position is not that modern yoga is invented. It is that a very old contemplative tradition acquired a substantially new physical vocabulary in the last century or so, and that both parts are real.
Where a teacher helps
Being able to say where something comes from, and where the evidence runs out, is part of teaching it well. A practice that does not need to overstate its age can be more interesting about what it actually is.

Questions people ask
Is yoga really five thousand years old?
The contemplative and philosophical tradition has very deep roots. The physical posture practice most people recognise today took much of its current form in the twentieth century, and the older texts describe far fewer postures, mostly seated.
How many postures do the old texts describe?
The Yoga Sutras name none, saying only that the seat should be steady and comfortable. The fifteenth-century Hatha Yoga Pradipika describes around fifteen, and the later Gheranda Samhita thirty-two, most of them seated or lying.
Who shaped modern yoga?
Krishnamacharya, teaching in Mysore from the 1930s, and his students Iyengar, Pattabhi Jois and Indra Devi are central. Indian physical culture of that period was also in active exchange with European gymnastics and physical training systems.
Does this mean modern yoga is not authentic?
It means it is a twentieth-century development within a much older tradition, which is a different thing from being invented. The philosophy, ethics and breath practices have genuine continuity; the posture vocabulary is largely recent.
