One of the students asked a question about the etiquette of class and it reminded me of famous stories of O’Sensei’s great patience in teaching but harsh reprimands for impoliteness or inattention.
There is an old Zen story about weeds growing along the path to the temple. The Elder sees them and reminds himself to fuss out the students who have not properly attended the gardens and path. The Younger is oblivious and walks past the weeds not realizing anything is amiss. The Righteous pulls one weed and congratulates himself on being erudite and correct.
The Master pulls them all; tosses them and any thoughts on the matter away.
