Yoga began as an ascetic discipline of renunciation. Today it is a global industry built around postures. This course traces how that transformation happened, from traditional texts to contemporary practice, and examines the trends and influential teachers that shaped it.
We follow the story from the earliest descriptions of yoga as inward restraint, through the tantric innovations of hatha-yoga, to the twentieth-century systems of asana devised for urban householders in the name of health and wellbeing. Along the way we consider the blending of Samkhya, Vedanta, and Tantra in modern teaching, the gymnastic parallels behind familiar postures, the scientific turn led by Kuvalayananda and Yogendra, the decisive influence of female practitioners, and the politics and business of yoga today.
The course is written and tutored by Daniel Simpson (MA in Yoga Studies from SOAS, University of London), author of The Truth of Yoga. It runs over seven weeks, with nearly seven hours of video lectures, a 160-page coursebook, an essay assessment, and invitations to live Zoom sessions with OCHS-affiliated scholars. Everyone who completes the course can receive a certificate for 12 hours of study, which Yoga Alliance-registered teachers can log as continuing education. For more, see our Yoga Studies pathway.
In the earliest descriptions of yoga, the body was an obstacle to spiritual freedom. Its desires kept people entangled in cycles of suffering, seeking gratification from worldly activity. The simplest response was to disengage, restraining the mind and the senses to focus within. The only reference to posture was a stable seat for meditation. Some practitioners also engaged in harsh austerities, such as standing on one leg for years on end – embracing discomfort to help them detach.
“The yogi never neglects or mortifies the body or the mind, but cherishes both. To him the body is not an impediment to his spiritual liberation nor is it the cause of its fall, but is an instrument of attainment.”
B.K.S. Iyengar, Light on Yoga
The first non-seated postures were arm balances, which were effectively warm-ups for subtler methods. They appeared in texts a thousand years ago, as the influence of Tantra inspired haṭha-yoga. Instead of mortifying the body, practitioners transformed it. Working with the breath, and new techniques known as mudrā, they used physical practice to raise vital energy up the spine, dissolving the mind. Over the centuries, haṭha-yoga became more dynamic, including a wider range of postures.
“Go into your own room and get the Upanishads out of your own Self. You are the greatest book that ever was or ever will be, the infinite depository of all that is.“
Swami Vivekananda to American students (1895)
Modern yoga often blurs the distinctions between different worldviews. Teachers say yoga means union and comes from Patañjali, combining ideas that contradict each other. The Yoga Sūtra is based on the dualist philosophy of Sāṃkhya. However, most explanations use non-dual ideas from Vedānta and Tantra. This began a long time ago, but the nineteenth-century influence of Vivekananda and Western esotericists was significant, blending Indian teachings with some of the theories that shaped New Age thinking.

Many common postures – including warriors and triangles – first appear in texts in the twentieth century. Sun salutations may not be much older. Yet both are now foundations of the popular style known as vinyāsa flow. It is difficult to say where they came from, not least since teachers imply they are timeless, but there are parallels with systems of gymnastics taught in India. Boundaries blurred between yoga and exercise as they were widely combined. Perhaps the most influential innovator was T. Krishnamacharya, who taught – among many others – B.K.S. Iyengar and K. Pattabhi Jois.
Yoga is often presented as therapy, healing anything from back pain to trauma. Its links to Indian medicine date back centuries, but the emphasis on health and wellness is more recent. In the early twentieth century, teachers of yoga sought to prove its effectiveness by scientific means. Two in particular shaped this process – Kuvalayananda and Yogendra, who had the same guru. They adapted his treatments for the general public, prescribing āsana, prāṇāyāma, and purifying kriyās. They also framed yoga in the language of progress, which others have embraced with technological metaphors.
Session Six: Female PractitionersMost traditional texts were composed by men and describe male ascetics. However, teachers and students today are primarily female. What accounts for this shift? The influence of women on the history of yoga is significant – particularly in cultural exchanges between East and West. Indian teachers borrowed ideas from female traditions of “harmonic gymnastics”, whose practitioners shaped the development of similar systems such as pilates and somatics. Some scholars even argue that the average modern yoga class owes more to Western women than to medieval texts on haṭha-yoga.
Debates about the ownership of yoga and misappropriation are now widespread. Commercialisation is rampant all over the world, while politicians have taken advantage of yoga’s popularity. In 2014, India’s prime minister won United Nations backing for an International Day of Yoga, held each year on June 21. Yet this event has sparked a backlash, due to connections with Hindu nationalism. This session reflects on tensions in modern yoga – particularly the quest for authenticity. As practices change, what keeps them anchored in tradition? Not everything is yoga because someone says it is.
