Henry P. Bowie, On the Laws of Japanese Painting…
“ The brush is the handmaid of the artist's soul and must be responsive to his inspiration. The student is warned to be as much on his guard against carelessness when handling the brush as if he were a swordsman standing ready to attack his enemy or to defend his own life; and this is the reason: Everything in art conspires to prevent success. The softness of the brush requires the stroke to be light and rapid and the touch delicate. ”
