§ 01 / KOAN

A paradox to sit with

What is value, when value is agreed upon?

A price is a rumor two strangers repeat until it becomes weather. We will not answer the question. We will trace it with the eye, the way one traces the curve of a dry river to remember where water once flowed.

§ 02 / MANUS INVISIBILIS

An argument with no arms

The hand is invisible because it is all of us, briefly agreeing.

A market is not a place. It is a soft consensus that flickers between strangers at the speed of rumor. Draw the curves and you will see fingers. Unsee the fingers and the curves remain.

A garden for motionless thought

Equilibrium is the silence between two offers.

Place the rocks where the curves agree. Rake the sand so the eye has something to follow while the mind has nowhere to go. Here, the market holds its breath.

矛盾
§ 04 / MUJUN — 矛盾

Three knots the mind cannot untie

Every solution was once a paradox that learned to smile.
