Outer alchemy tried to turn lead into gold. Internal alchemy works on a different metal: you.
What it is Internal alchemy — neidan in the Daoist tradition — treats the body as a laboratory. Breath, attention and stillness are the tools; the goal is to refine your own energy into something clearer and stronger.
The Three Treasures - Jing (essence): your physical foundation — sleep, food, vitality. - Qi (energy): the breath and life-force moving through you. - Shen (spirit): awareness, clarity, the light behind the eyes. The classic path is to protect your jing, grow your qi, and let both brighten your shen.
The cauldron Practitioners focus on the lower dantian, a point roughly two finger-widths below the navel. Think of it as the furnace where the work happens.
A five-minute starter practice 1. Sit upright, feet flat, hands resting on your lower belly. 2. Breathe slowly through the nose, letting the belly rise first. 3. On each exhale, imagine warmth gathering under your hands. 4. After five minutes, rest your attention there for three quiet breaths before getting up.
As above, so within The Western alchemical stages — nigredo (blackening), albedo (whitening), rubedo (reddening) — map neatly onto inner work: face the shadow, clean it up, then live it out. Tarot is a great companion here; the Major Arcana reads like a map of that same transformation.
This is a spiritual practice, not medical advice.
