Yoga

Yoga is the name in Indian thought for a family of disciplines that work on body, breath, and mind together, aiming at a freedom the traditions call liberation. The Sanskrit word derives from a root meaning to yoke or join, and the same root gives English yoke; what is joined, and to what, is exactly what the various schools dispute.

The earliest layers are hard to date, but practices of restraint and inward concentration are already visible in the older Upanishads and in the Bhagavad-Gita, where the term covers several distinct paths — the yoga of action, of devotion, of knowledge. The text that gave the word its classical shape is the Yoga Sutras attributed to Patanjali, compiled in the early centuries CE, which sets out the eightfold path: ethical restraint, observance, posture, breath-control, withdrawal of the senses, concentration, meditation, and samadhi, the absorbed state in which, in the system’s own terms, the seer rests in its own nature. Patanjali’s framework is dualist, drawn from Sankhya philosophy: liberation is the disentangling of pure consciousness from the matter it has been mistaken for. Later, the medieval hatha traditions — the Hathayogapradipika among their manuals — developed the work on the physical body, posture, and the channels of subtle energy, understood as preparation for the same ascent.

These are tradition-internal claims, and the schools hold them differently: where Patanjali seeks the isolation of consciousness, the devotional and Vedanta-tinged readings seek union with the divine, and the tantric and hatha currents map a subtle physiology the Sutras barely mention. What scholarship establishes is narrower — that “yoga” never named one thing, that the texts span many centuries and incompatible metaphysics, and that the posture-centred practice now most familiar is, in large part, a modern formation. Its nineteenth- and twentieth-century shape owes much to the encounter with European physical culture and to teachers who carried the word abroad; Vivekananda’s lectures, gathered in his collected works, did more than any single source to fix “yoga” in the Western mind, recasting it as a science of the inner life.

The Theosophical movement absorbed the vocabulary early, and Western esotericism has long reached for yoga as evidence of a shared inner discipline beneath the world’s religions — the samadhi of Patanjali set beside the contemplative union of other traditions. The comparison is suggestive, and the family resemblances are real; they are also not interchangeable — each system means something exact by its terms and reaches its goal by its own map. What the long history shows is less a single practice handed down intact than a word repeatedly taken up and refitted to new ends, its older senses surviving inside the newer ones.
