Today was another one day sesshin. The day begins with the jikido, who is responsible for the meditation hall, waking up everyone in the sangha at 3:45. He strikes the drum three times, followed by three strikes of the unpan (metal board). After this, he will run down the corridors with a bell.
Not only is he to wake up everyone, but his vigor is to motivate the rest of the community. What the hidden camera in Antaiji caught this morning was not exactly a good example.
