Testing is the Tradition
The Common Roots
Consider Yantra Yoga (Tibet) and Hatha Yoga (India). Yantra Yoga is best understood as a sibling of Hatha Yoga, or more precisely as its Buddhist counterpart. Both grew out of the Tantric world of medieval India, and scholars continue to debate how much each owes to the other. They diverged in their transmission contexts. Yantra Yoga was carried into Tibet and refined within Buddhist lineages, while Hatha Yoga developed in Śaiva-influenced circles and was later associated with the Nāth Siddhas.
The Original Somatic Labs
At the root of both were the Mahasiddhas: non-conformist practitioners who worked outside rigid monastic and orthodox lines. They were not unsystematic. They were somatic innovators with a method, experimenting with posture, breath regulation (prana-vayu), muscular locks (bandhas), and sensory withdrawal to influence the mind and subtle body directly. This happened long before any of it was codified into neat lineages.
Their metaphysics differed, and the Buddhist and Hindu frameworks disagree about the nature of the self. What they shared was a working surface: the living, embodied practitioner, and the conviction that the body’s own machinery could be used to change the mind.
One Milieu, Two Pathways
As these practices migrated and adapted over centuries, two distinct expressions emerged.
In Tibet, somatic techniques were embedded in monastic and cave-retreat systems, such as the Six Yogas of Naropa and the Dzogchen traditions, to clear the channels (tsa) and vital winds (lung) for meditation. Tibetan lineages carried a dynamic, breath-coordinated style of movement with its own continuous history. It was never frozen. New Trulkhor (Yantra Yoga) systems kept being revealed through the ‘terma’ (hidden treasure) tradition.
In India, similar tools were taken up by radical orders such as the Nāth Siddhas, associated with figures like Matsyendranath and Gorakhnath. The Hathapradipika, compiled well after the practices it records, describes only a handful of mostly seated postures, alongside cleansing practices, bandhas, and breath retention. The large catalogues of asana came later, and today’s postural classes are largely a twentieth-century development. This was a continuous synthesis, absorbing Śaiva, Vaiṣṇava, and Buddhist elements, and codified only after the practice had matured.
Not Every Innovation Is a Correction
It would be easy to conclude from this that innovation is always good. It isn’t. The Mahasiddhas and Nāths did not innovate for novelty’s sake. They tested their tools against a purpose and kept what worked. That is a very different thing from change as fashion.
Some innovations correct a tradition that has hardened into habit. Others simply drift, or follow the market. The question is never whether something is new, but whether it still serves the work: does it do what it claims on the living person? That test is hard to apply honestly, because “works” can quietly come to mean “sells.” It is also the only test that separates renewal from drift.
Two Streams, One Method
Tibetan Yantra Yoga and Indian Hatha Yoga are not unrelated traditions. They are two streams from a shared Tantric milieu, diverging in their transmission contexts, and neither stood still.
Yoga has never been a museum piece. Its power has depended on practitioners willing to test, adapt, and refine its tools on the living human being, and on the discipline to tell a correction from a trend.
To understand what “classical” yoga means, we have to look beyond static snapshots of history and recognize that testing, not preservation, is what has kept the tradition alive.
