What is the reason monks strike a wooden fish (mokugyo) when chanting sutras and the like?

The wooden fish drum makes a pleasant pok-pok sound, but what is the original meaning behind monks striking it while chanting sutras? Surprisingly, the answer is “to keep the monks from getting drowsy.” In the past, many monks and trainees would nod off during long recitations, so they used a wooden fish—modeled after a creature that is always keeping its eyes open—to convey the idea: “Keep your eyes open like a fish and devote yourself to practice.” It’s also said that the sound of the wooden fish helps dispel worldly desires.

Next time you have a chance to hear it, try listening with that in mind!
