Yoga is everywhere today – in fitness apps, hospital wellness programmes, school morning assemblies, and Olympic stadiums. But this ancient discipline has a story that stretches back thousands of years, long before spandex and studio lighting. Understanding where yoga truly comes from – and how it has changed across centuries – gives us a richer sense of what we practise when we step onto a mat, or simply sit still and breathe.

What does the word “yoga” actually mean?
The word yoga comes from the Sanskrit root yuj, which means “to join” or “to unite.” According to yogic scriptures, the practice leads an individual toward the union of personal consciousness with universal consciousness – creating harmony between the human body and mind, and between the individual and nature. This goal of integration, of bringing together what feels scattered or separate, is the thread that runs through every stage of yoga’s history.
That single word – union – contains enormous depth. It implies that human beings are, in some important sense, divided: body from mind, thought from action, self from the world around us. Yoga, across all its forms, is the sustained effort to close those gaps.
The earliest roots: Vedic India
Yoga’s origins can be traced to northern India over 5,000 years ago. The word itself first appeared in the Rig Veda, the oldest of the four sacred Vedic texts, composed roughly between 1500 and 1000 BCE. The Rig Veda is a vast collection of over a thousand hymns and mantras, and in this earliest context, the term yuj referred quite literally to the yoking of horses to a chariot – a physical act. Vedic priests then extended this image into metaphor: to perform a sacred ritual was to yoke oneself to the cosmic order. To chant or pray effectively required yoking mind and speech together.
The Vedic age priests, known as Brahmins, performed elaborate sacrifices called yajnas that required sustained mental focus. Researchers believe the postures these priests adopted during these rituals may have evolved into what we today recognise as yoga asanas. Early on, yoga was less a physical discipline and more a spiritual technology – a way of directing attention inward.
The next major development came with the Upanishads, a body of texts composed between roughly 800 and 200 BCE. Yoga was refined and developed by Rishis (sages) who documented their practices and beliefs in the Upanishads, a huge body of work containing over 200 scriptures. Where the Vedas focused on external ritual, the Upanishads turned the gaze inward. They explored the nature of the self, the meaning of consciousness, and the path toward moksha (liberation). Some of the earliest systematic teachings on yogic philosophy are found here, emphasising the unity of all life and the pursuit of self-realisation.
Classical yoga: Patanjali and the Yoga Sutras
The most decisive moment in yoga’s intellectual history came with the sage Patanjali, who compiled the Yoga Sutras – 196 concise aphorisms that systematised all existing yogic knowledge into a coherent framework. Written around 400 CE, these sutras offered a path to transcend human suffering and reach self-realisation and ultimate freedom.
Patanjali’s central contribution was the Ashtanga Yoga system – the eight-limbed path. “Ashta” means eight and “anga” means limb, and these eight steps serve as guidelines on how to live a meaningful and purposeful life – prescriptions for moral conduct, self-discipline, attention toward health, and acknowledgment of our spiritual nature.
The eight limbs move progressively from the outer world to the inner:
- Yama – ethical guidelines for living in relation to others (non-violence, truthfulness, non-stealing)
- Niyama – personal disciplines and spiritual observances (purity, contentment, self-study)
- Asana – physical posture, described by Patanjali as “stable, firm, and comfortable”
- Pranayama – control and regulation of the breath
- Pratyahara – withdrawal of the senses from external distractions
- Dharana – concentration: holding the mind on a single point
- Dhyana – meditation: a continuous, uninterrupted flow of awareness
- Samadhi – a state of complete absorption, where the distinction between the meditator and the object of meditation dissolves
Notice that asana – physical posture, the element most associated with yoga today – is just the third of these eight limbs. For Patanjali, the body was a gateway, not the destination. The Yoga Sutras remain a foundational text in yoga philosophy worldwide, studied as much today as they were centuries ago.
Yoga’s growth across Indian philosophical traditions
Yoga did not develop in isolation within any single tradition. As Indian philosophical thought flourished in the centuries around 500 BCE and onward, yogic ideas took root in Jainism, Hinduism, and Buddhism in distinct but overlapping ways.
Yoga and Jainism
In Jainism, the emphasis fell on the liberation of the spirit through rigorous ethical conduct and ascetic discipline. The great teacher Rishabhadev, who was a central figure in the Jain tradition, emphasised efforts dedicated to the liberation of the spirit. Later, the eighth-century Jain philosopher Haribhadra wrote the Yogadrishtsamuccaya, developing a comprehensive Jain yoga system that drew from Patanjali’s Yoga Sutras while giving them a distinctly Jain philosophical framework. In Jainism, “yoga” was understood in the broadest sense: as any discipline of body, speech, and mind oriented toward liberation (moksha).
Yoga and Buddhism
The Buddhist encounter with yoga was equally rich. The word “yogin” is applied to adepts in all three major branches of Buddhism – Hinayana, Mahayana, and Vajrayana – and the Buddha himself is frequently described as an inveterate meditator. The goal of Buddhist practice – overcoming suffering through understanding the nature of mind – ran parallel to yogic aims.
The most significant intersection came with the Yogachara school of Mahayana Buddhism, which flourished from around the 3rd to 5th centuries CE. The Yogachara (“Yoga Practice”) school was the earliest Buddhist tradition to use the term “yoga” to denote its philosophical system. Also known as Vijรฑฤnavฤda (“Doctrine of Consciousness”), Yogachara offered a systematic analysis of perception and consciousness, along with meditative disciplines designed to eliminate cognitive errors that prevent liberation from suffering.
In Mahayana Buddhism, the Yogachara path involved eight steps of meditation described as “calmness” or “insight.” While it borrowed the yogic framework of disciplined mental cultivation, it grounded that framework in Buddhist analysis of how the mind constructs experience – and how liberation from suffering depends on seeing through those constructions. This focus on analysing consciousness and reducing suffering became the core of the Yogachara contribution to yoga’s intellectual history.
The Bhagavad Gita and the yoga of everyday life
No account of yoga’s history is complete without the Bhagavad Gita, composed around 200 BCE and forming part of the great epic Mahabharata. The Gita introduced yoga not as a reclusive or monastic practice but as something available to anyone living an active life in the world. It presented three primary paths: Karma Yoga (the yoga of selfless action), Jnana Yoga (the yoga of knowledge and wisdom), and Bhakti Yoga (the yoga of devotion). The key teaching was that liberation does not require renouncing the world – it requires performing one’s duties without attachment to results.
This democratisation of yoga – the idea that a warrior, a farmer, or a merchant could pursue spiritual union through their daily work – was a radical expansion of earlier, more elite traditions. The Gita remains one of the most widely read spiritual texts in the world, and its influence on how yoga is understood cannot be overstated.
Hatha Yoga: the body as a path
Between roughly the 9th and 15th centuries CE, a new development emerged: Hatha Yoga. Where earlier traditions had treated the body primarily as an obstacle or instrument to be disciplined, Hatha Yoga placed the physical body at the centre of spiritual transformation. Drawing from Tantric traditions that arose in the medieval period, Hatha Yoga used physical postures (asanas), breath control (pranayama), and energy locks (bandhas) as direct means of awakening dormant spiritual energies.
Key texts like the Hatha Yoga Pradipika (14th century) and the Gheranda Samhita (17th century) detailed these practices in systematic form. Hatha Yoga’s insistence that physical purification was a prerequisite for mental and spiritual development laid the groundwork for almost every modern physical yoga practice, from Ashtanga Vinyasa to Iyengar and beyond.
Yoga’s revival during the nationalist movement
By the 18th and early 19th centuries, yoga had faded somewhat from mainstream practice, particularly under colonial influence. But the nationalist movement of the late 19th and early 20th centuries brought it back – and with new energy. Yogic practices flourished in modern India as a form of bio-political resistance to British rule, with the revival of Hatha Yoga seen as a way to build physically strong and culturally rooted bodies capable of asserting national identity.
Swami Vivekananda’s landmark address at the World Parliament of Religions in Chicago in 1893 introduced yoga’s philosophy to a global audience for the first time. Back in India, yoga researcher Jagannath Gune (Swami Kuvalayananda) established a research centre in 1924 where scientists were invited to study yoga systematically – effectively bridging the ancient practice and modern science. Yoga was becoming both a symbol of cultural pride and a subject of rational inquiry.
Yoga after independence and its global journey
Teachers like B.K.S. Iyengar, Pattabhi Jois, and T.K.V. Desikachar – all students of the pioneering teacher Krishnamacharya in Mysore – carried distinct styles of practice to international audiences through the 1950s to 1980s. Indian yogis who migrated to the West taught in universities, opened studios, and wrote books that made yoga accessible to millions who had no prior connection to its spiritual roots.
The transformation was significant: in the West, yoga was often reframed primarily as a physical and wellness practice. The spiritual dimension, while never entirely absent, was given secondary status because, as historians note, science dominated the Western worldview and presenters emphasised yoga’s practical health benefits. This reframing changed yoga itself – but it also dramatically accelerated its spread.
Today, yoga is practised in over 100 countries, with an estimated 300 million practitioners worldwide. In 2014, India successfully proposed to the United Nations that June 21 be declared International Yoga Day, recognising its global cultural and health significance. The first International Yoga Day on 21 June 2015 saw mass yoga sessions held simultaneously across the world – a remarkable moment for a practice that began in the forests and river valleys of ancient India.
What yoga has always been – and what it is becoming
Across its long history, yoga has never been a single, fixed thing. It has been a sacrificial ritual, a philosophical inquiry, a monastic discipline, a Tantric practice, a tool of political resistance, a form of physical culture, and a global wellness industry. Each era shaped it differently, and yet certain threads persist: the orientation toward inner life, the cultivation of awareness, and the aspiration to reduce suffering – both personal and collective.
This history also reminds us that when Mahayana Buddhists developed the Yogachara system to understand consciousness and eliminate the cognitive errors that cause suffering, or when Jain teachers emphasised ethical conduct as a form of yoga, or when Vedic sages described the yoking of mind and speech – they were all pointing at the same fundamental challenge: how do we live in a way that is integrated, aware, and free?
Modern practice, whether it involves dynamic physical sequences, silent meditation, or breathwork, inherits all of these layers. Knowing that history does not diminish the contemporary practice – it deepens it.
What do you think? Yoga has been shaped by Hinduism, Buddhism, and Jainism, by colonial history, by science, and by global commerce – and it keeps changing. Which aspects of yoga’s history do you find most surprising or overlooked? And as yoga continues to evolve in the 21st century, what do you think should be preserved from its ancient roots?
