Only When The Fisherman Keeps His Nets Intact, Keeps His Boat Repaired,
And Studies The Condition Of Fish And Water Does Going Out To Fish Become A
Mere Formality.
Only when the fisherman keeps his nets intact, keeps his boat repaired,
and studies the condition of fish and water does going out to fish become a
mere formality. Then fish fall into his hands as if guided by invisible
lines.
