ink
It controls you, not you control it.
I believe, even ancient masters had an unexpected drops, uncontrolled spreads and unforgiving absorption of the ink that they did not intend. It warps your paper, disappears where you wanted it to be seen, and spreads wide where you wanted to control it.
That is the whole point - to let it go. Let it live by itself. Let it act.
You are just a tool.
Blackest black, dark and deep - for intense love and strength.
Grey washes - for a pause between storms.
Dry strokes - for Self control and knowledge.
Self blending, soft and gentle - for subtle emotions, that you are not able to describe in words.
let it go.
