Mood is what is present.
Choice is cause meeting condition.
Action is future condition.
## Lessons
1. Before ink, there is only the hand and the sheet before it. Nothing more is needed. Practice is lost when the hand reaches past what is present. [[01_lesson|Lesson I]].
2. One motion is enough to shape the next. What repeats becomes habit; what becomes habit becomes cause. [[02_lesson|Lesson II]].
3. First see the gesture; then make it. A hand that cannot see before moving writes blindly. [[03_lesson|Lesson III]].
4. The eye and hand now bow to one form. When seeing and doing serve one form, the stroke becomes honest. [[04_lesson|Lesson IV]].
5. To paint truly, first know the ink. [[05_lesson|Lesson V]].
6. The drop shows its form; the brush sets it down. [[06_lesson|Lesson VI]].
7. Nothing is painted, yet the stroke is already shaped. The brush will reveal it in time. [[07_lesson|Lesson VII]].
8. The brush moves once. What was hidden and what is present are no longer two. [[08_lesson|Lesson VIII]].
9. A stroke begins by knowing where it will appear. [[09_lesson|Lesson IX]].
10. The name does not move the brush. It keeps the hand from wandering. [[10_lesson|Lesson X]].
11. The brush does not disturb what has already become clear. [[11_lesson|Lesson XI]].
12. The brush may be steady, yet a fine stroke asks for ink that will not run. [[12_lesson|Lesson XII]].
13. The brush meets the ink. Holding opens the way; unknown remains open; running closes the stroke. [[13_lesson|Lesson XIII]].
14. The hand may hold nothing. See the empty hand. Do not ask it for a line. [[14_lesson|Lesson XIV]].
15. Each ink keeps its own nature. The brush must not pretend otherwise. [[15_lesson|Lesson XV]].
16. Change the ink while the brush is still. See what remains. Then the line can be trusted. [[16_lesson|Lesson XVI]].
