The Twelve Operations · Operation 2 · Nigredo
Solutio Dissolution
In the vessel. What remains after the fire is immersed in water until it loses its shape. In the images, the king bathes and dissolves.
In a life. Immersion in emotion, memory and the unconscious. It is lived as overwhelm: boundaries you thought were permanent turn out to be soluble, and the water finds every crack.
Which boundary of yours is dissolving, and are you fighting the water?
The full section on dissolution, with the other eleven operations and the four stages, is in The Magnum Opus.
