Doan's corner at the Empty Hand Zen Center. The doan is the one who rings the bells during service and before and after zazen, or seated meditation. The big bell to the left is called a "keisu"; the smaller one to the right is a "shokei". Each bell has its own striker. To the far right is the "inkin", or small, handheld bell. The wooden clappers shown to the right of the inkin are used during kinhin, or walking meditation. And then there's the clock. Used to time periods of zazen. Tells the doan when to hit the shokei. At times, this clock can move very, very slowly.
