If Not Physical Fitness, What Was Yoga Originally For?

Indian yogi in meditation
The original purpose of yoga was not to strengthen the body, but to free the mind.

Millions of people practise yoga for stronger backs, greater flexibility, or relief from stress. These are genuine benefits. But they were never yoga’s original purpose.

The first yogis were not searching for physical fitness. They were searching for freedom.

More than two thousand years ago, Indian philosophers concluded that the root of human suffering lies not in the body but in the mind—or, more precisely, in our mistaken understanding of who we are. Yoga emerged as a practical method for overcoming that mistake.

The First Meaning of Yoga

One of the earliest surviving discussions of yoga appears in the Katha Upanishad, composed around the fourth century BCE. There, the brahmin boy Nachiketa rejects wealth, power, and a long life to ask Yama, the god of death, a single question: What becomes of us after death?

Yama replies that this knowledge cannot be gained through study alone, but only through yoga, which he defines as ‘the firm holding back of the senses’:

When the five organs of perception become still, together with the mind, and the intellect ceases to be active: that is called the highest state.

From the beginning, then, yoga was not a form of exercise but a discipline of inner stillness.

Why We Suffer

Classical yoga rests on Samkhya, one of the oldest schools of Indian philosophy. It seeks to explain both the nature of reality and the origins of human suffering.

According to Samkhya, reality consists of two fundamental principles. The first is Purusha, pure consciousness or the witnessing self. The second is Prakriti, which includes not only the physical world but also the body, the senses, the ego, and even the mind itself.

An ancient Indian image captures the idea beautifully. Two birds perch in the same tree. One pecks eagerly at the fruit, tasting now sweetness, now bitterness. The other simply watches. The first bird represents the self absorbed in the changing experiences of life; the second, the silent witness that remains untouched by them.

Yoga teaches that we mistake ourselves for the first bird when our true nature is the second. We identify with our thoughts, emotions, and fears, forgetting that these are passing experiences rather than our deepest identity.

Yoga Beyond Meditation

Composed in the centuries around the beginning of the Common Era, the Bhagavad Gita broadened the meaning of yoga. Alongside meditation, it described the yoga of knowledge (Jnana Yoga), selfless action (Karma Yoga), and loving devotion (Bhakti Yoga).

Its central message is that freedom comes not from withdrawing from life but from living without attachment to success or failure. Like Stoicism, the Bhagavad Gita teaches that peace of mind depends less on what happens to us than on how we meet it.

As the god Krishna tells the warrior Arjuna:

Work done for a reward is much lower than work done in the Yoga of wisdom.

Yoga was no longer confined to the forest or meditation hall. Everyday life itself could become a spiritual practice.

Patanjali’s Yoga

The philosopher Patanjali transformed these ideas into a practical discipline in the Yoga Sutra, the foundational text of classical yoga. He famously defined yoga as:

Yoga is the cessation of the fluctuations of the mind.

To achieve this, Patanjali described an eightfold path combining ethics, posture, breath control, concentration, and meditation, culminating in samadhi, complete absorption. Significantly, the physical postures (asanas) formed only one stage of this much larger discipline.

How Yoga Became Exercise

If yoga began as a path to liberation, how did it become associated with stretching and physical fitness?

The answer lies in its long evolution. Later traditions, especially Hatha Yoga, placed increasing emphasis on physical postures, though still in pursuit of spiritual liberation.

The decisive shift came in the late nineteenth and early twentieth centuries, when Indian teachers such as Tirumalai Krishnamacharya presented yoga in dialogue with Western physical culture and modern medicine. Their students—including B. K. S. Iyengar and Pattabhi Jois—introduced these new forms of postural yoga to Europe and America, where they proved enormously popular.

Modern yoga is therefore not a misunderstanding of the tradition so much as one particular branch of it. While its philosophical roots remain ancient, its familiar image as a form of exercise is surprisingly modern.

The yoga practised by millions today is therefore only one chapter in a much older story.

The Original Purpose of Yoga

Millions of people come to yoga hoping for stronger backs, greater flexibility, or relief from stress. The first yogis hoped for something altogether more ambitious: freedom from suffering through a deeper understanding of the self.

Whether or not we accept their answers, the first yogis were asking one of humanity’s oldest and most profound questions:

Who am I?

For them, the search for that answer was the true purpose of yoga.

Yoga is one of the six orthodox schools of Indian philosophy.

darshana is an outlook, a philosophy, literally, a “vision.” The term darshana is especially associated with the six orthodox schools of Indian philosophy, the so-called shaddarshana, or “six visions.” What makes them orthodox, and therefore Hindu, is that they accept the authority of the Vedas. With good reason, the shaddarshana are often presented in pairs: Samkhya-Yoga, Nyaya-Vaisheshika, and Mimamsa-Vedanta. In this post, I shall, of course, be focussing on Samkhya-Yoga.

The Samkhya School

The founder of the Samkhya school is held to be Kapila, who lived, perhaps, in the sixth century BCE. Little is known about him. He is sometimes described as an avatar of Vishnu or the grandson of Brahma. He is mentioned by Krishna in the Bhagavad Gita as the greatest of sages: “Amongst the gandharvas I am Chitrath, and among the siddhas, I am sage Kapila.” According to Puranic lore, his meditation produced such intense inner heat that, when they disturbed him, he incinerated the Sagarputras, the 60,001 sons of King Sagara, simply by opening his eyes.

In the Buddhist tradition, the students of Kapila built the Shakya capital of Kapilavastu. The Buddha, who was raised in Kapilavastu, was therefore steeped in Samkhya philosophy, explaining the affinities between Samkhya and Buddhism.

Kapila is held to have authored the Samkhya Sutra, although the extant text appears to be medieval in origin. Instead, the school’s primary text is the Samkhyakarika by Ishvarakrishna, who lived in the third or fourth century CE.

In the first verse, Ishvarakrishna states the aim of Samkhya: to eliminate the three forms of dukkha (suffering): internal, from physical and mental disease; external, from outside threats, especially other people; and divine, that is, from natural disasters.

Samkhya is a radical dualism that holds that the universe is made up of two independent, infinite, and eternal realities: Purusha (souls) and Prakriti (matter or nature). The Purushas are conscious but have no attributes. They are pure ‘witness consciousness.’ Prakriti is composed of the three gunas (qualities or tendencies of matter), sattva (preservation, harmony), rajas (creation, passion), and tamas (destruction, apathy). 

Initially, the gunas are in equilibrium. But at its approach, Purusha disturbs this equilibrium in favour of rajas, and this imbalance sets off material creation.

Comparisons With Western Dualism

Unlike Western dualism, which is between mind and matter, Samkhyan dualism is between self and matter—with “matter” encompassing most of what Westerners would consider “mind” (intellect, ego, emotions, etc.)—everything, in fact, except witness consciousness, of which mind is the instrument.

Also, unlike Western dualism, Samkhyan dualism is atheistic or agnostic. Although an orthodox school, Samkhya is remarkably silent about God and the Vedas.

The Samkhyan Account of Creation

At the approach of Purusha, undifferentiated Prakriti evolves 23 tattvas (elements, aspects), first buddhi (intelligence), and from buddhi ahamkara (ego or self-consciousness).

Under the influence of sattva gunaahamkara yields the five organs of sense (eyes, ears, nose, skin, tongue), the five organs of action (arms, legs, speech, organs of elimination, organs of creation), and manas (mind).

Then, under the influence of tamas gunaahamkara yields the five subtle elements (sight, hearing, smell, touch, taste), from which the five material elements (earth, air, water, fire, ether) emerge.

Notice that the material world is last in the order of creation. Its evolution from the five senses suggests that the world is an illusion, although this is never explicitly stated.

Manas has a special role in mediating between the ten organs, the five senses, and the world without. Being of Prakritibuddhiahamkara, and manas are not conscious. However, they appear to be conscious and are set into motion by proximity with Purusha—functioning, as it were, by reflected consciousness.

The Samkhyan Account of Liberation

Adding Purusha and Prakriti to the 23 tattvas makes a total of 25 tattvas—of which 24 are of Prakriti. Nonetheless, it is for the sake of Purusha that the differentiation occurs, to provide it with experience and, in time, with liberation (moksha). By reflecting the consciousness of PurushaPrakriti is showing Purusha to itself.

Purusha and Prakriti are like a lame man and a blind man, lost in the wilderness. The blind man carries the lame man, who guides his steps. Both are looking for their way home, to moksha, when they will part ways. But having never traveled, the lame man is avid of experience and so enthralled by his adventure that he forgets about his destination.

To be consistent with the universal law of karma, Samkhya assumes that a Purusha that is bonded to Prakriti (that isjiva), has two bodies: a gross, mortal body, and a subtle body made up of the higher functions which transmigrates according to past merit. The continuity of the subtle body enables the Purusha to keep on learning through numerous incarnations.

Final liberation consists in the realization of the separateness of Purusha and Prakriti. This involves a process of involution, or “going back to the womb”—that is, reversing, through intellect and understanding, the process of evolution from the material elements back to undifferentiated Prakriti and beyond.

In short, salvation consists in counting backwards.

The Yoga School

Samkhya exerted such a profound influence on Yoga that the two schools are sometimes merged as Samkhya-Yoga. But whereas Samkhya emphasizes knowledge and discrimination as the path to liberation, Yoga rather emphasizes discipline.

Although Yoga essentially borrows the metaphysics of Samkhya, it introduces a twenty-sixth tattva, namely, Ishvara, or “the Lord”—for which reason it has been called “Theistic Samkhya.” The nature of “Ishvara” is open to interpretation, but it may be regarded as a special Purusha that is unentangled and, therefore, inactive.

The Yoga Sutra of Patanjali

In the second century BCE, or perhaps the fifth century CE, Patanjali collected the ideas around yoga in the Yoga Sutra. These 196 verses became the foundational text of Yoga, which, towards the end of the first millennium, began to be mentioned as a separate school.

Patanjali’s synthesis influenced all other schools of Hindu philosophy, which regard it as authoritative. It is sometimes referred to as Raja Yoga (Royal Yoga) or Ashtanga Yoga (Eight-Limbed Yoga) to distinguish it from the many other forms of yoga, such as Jnana, Karma, Bhakti, Mantra, and Tantra—which are, of course, more complementary than mutually exclusive.

The Yoga Sutra has four sections: Samahdi (Concentration), Sadhana (Practice), Vibhuti (Yogic or Magical Powers), and Kaivalya (Isolation or Liberation). In the first section, Patanjali defines yoga as “the cessation of mental fluctuations” (chitta vritti nirodha)—with chitta (mind) assimilated in the Samkhyan system to buddhiahamkara, and manas. In the third section, he warns against practicing yoga for the perverted purpose of acquiring yogic powers—suggesting that this sort of thing may have been common.

Ashtanga or Eight-Limbed Yoga

The eight stages of Patanjali’s Yoga are:

  1. Yama (abstinence or restraint)
  2. Niyama (discipline or observances)
  3. Asana (‘seat’, posture)
  4. Pranayama (breath control)
  5. Pratyahara (withdrawal of the senses)
  6. Dharana (concentration of the mind on some object)
  7. Dhyana (steady meditation on that object) and
  8. Samadhi (absorption, ecstatic union with the ultimate).

The first two stages are ethical preparations. Yama involves abstinence from injury, falsehood, stealing, lust, and avarice. Niyama involves purity or cleanliness, contentment, austerity, study, and devotion to God.

The next two stages are physical preparations, each involving a series of exercises to remove physical or bodily distractions.

The fifth stage involves taking control of the mind by emptying it of impressions.

The remaining three stages, which may take several lifetimes to perfect, aim at increasingly heightened states of awareness and return.

According to Patanjali, the five kleshas (poisons, obstacles to Yoga and liberation) are ignorance, ego, attachment or desire, aversion to unpleasant things or truths, and fear of death and desire to live.

Final Remarks

The aim of yoga, and ascetic practice in general, is essentially to react against ordinary human habits, which entangle us, or our Purusha, with Prakriti, to the extent that Purusha identifies with Prakriti and more particularly with the restless chitta and its manifold modifications.

This is a far cry from the yoga practised in the West as a form of physical culture, with postures borrowed from Hatha Yoga and optional spiritual sprinkling for stress relief. Even Hatha Yoga is about a lot more than that.
