grind your inkstick gently but move your brush vigorously
Proverb advising that in calligraphy, one should grind the inkstick with a light, gentle touch (like a hungry ghost, weak and delicate) but wield the brush with bold, vigorous strokes (like an ogre, strong and forceful). The literal gloss is provided for cultural reference.
My calligraphy teacher taught me how to hold the brush, saying, 'Grind your inkstick gently but move your brush vigorously.'
