Why we keep our eyes open during zazen

“If we close our eyes (during zazen), the darkness may provide us some relief from visual distraction and give us a feeling of peace and calm. But in zazen, we keep our eyes open. If we want to close our eyes because we feel distracted by what our eyes see, we need to understand that it is our minds that are distracted, not our eyes.”

(A quote from the book, Zen at Work.)
