The eight limbs: from body to breath to mind.

Body — the foundation

Yama and niyama are the ethical and personal disciplines: how you treat others, and how you treat yourself. In clinical terms this is the groundwork of self-care — sleep, honesty about habits, the decision to take your own health seriously.

Asana is posture and physical stability. This is the part most people mean when they say “yoga”. It releases tension, improves circulation and builds the body awareness needed for everything that follows.

Breath — the bridge

Pranayama is breath regulation, and it is the pivot of the whole system. This is the stage that directly engages the vagus nerve and shifts the body out of sympathetic dominance — the mechanism described on the vagus nerve page.

Pratyahara is withdrawal of the senses: deliberately reducing input. In a working life of constant notification and interruption, this is less an ancient discipline than a practical necessity.

The first five limbs prepare the ground; the last three are the inner work.

Mind — integration

Dharana is concentration — sustained attention on a single object. Dhyana is meditation, where that attention becomes continuous. Samadhi is deep stillness and integration.

These last three are what the tradition calls the inner work. Clinically, focused attention strengthens the mind–body connection, supports recovery and is associated with measurable changes in stress physiology.

Why teach it this way

The first five limbs prepare the ground; the last three are the inner work. Taught as a structured discipline with a physiological rationale, rather than as a belief system, yoga becomes a clinical tool. That is the distinction that matters to patients who would otherwise dismiss it, and it is how Dr Vimple teaches it.
