Yoga

Yoga — from the Sanskrit yuj, "to yoke" or "unite" — is a family of Indian disciplines for harnessing body and mind toward liberation. The word covers far more than the posture practice familiar in modern studios: it runs from ancient meditative and ascetic traditions through Patañjali's classical system and medieval Haṭha yoga to the globally popular movement of the last hundred years.

Ancient roots

Yoga grew out of the same renunciant and contemplative currents as early Buddhism and Jainism (the The Renunciants of Ancient India), with deeper antecedents in the Upaniṣads. Its concern was mokṣa — release from the cycle of rebirth — pursued through inward discipline, breath control, and meditation rather than outward ritual.

Classical yoga: Patañjali

The first systematic statement is the Yoga Sūtras of Patañjali (c. 400 CE), which define yoga as "the stilling of the fluctuations of the mind" and lay out an eight-limbed (aṣṭāṅga) path. Strikingly, only a handful of its aphorisms concern āsana — and there it means a steady seated posture for meditation, not a gymnastic repertoire. See Patañjali Compiles the Yoga Sutras.

Haṭha yoga

The physical, body-centered yoga of postures, locks, and breath control (prāṇāyāma) developed later, especially within the Nāth tradition between roughly the 11th and 15th centuries, in texts like the Haṭha Yoga Pradīpikā. Even so, premodern Haṭha yoga involved far fewer standing postures than today's practice.

Modern postural yoga

The yoga practiced worldwide today is, to a striking degree, a 20th-century creation. As the historian Mark Singleton has documented, teachers such as T. Krishnamacharya and his students B.K.S. Iyengar and K. Pattabhi Jois synthesized older Haṭha elements with European gymnastics and the physical-culture movements of the colonial era to produce the flowing, posture-rich systems now exported globally.

Perspectives

There is a persistent popular claim that modern yoga is an unbroken 5,000-year-old tradition. Scholars including Singleton, James Mallinson, and David Gordon White show a more honest picture: a genuinely ancient meditative and ascetic lineage, a medieval body-practice, and a modern, partly Western-influenced reinvention — each real, but not the same thing. Recognizing the layers does not diminish yoga; it clarifies what is actually old and what is new.
