Like hearing thunder

It is a Zen expression that describes a state in which one cannot bear anything. Its usage can be seen in several Zen Buddhist sayings, and it does not necessarily have a positive meaning, but I chose it because I wanted to be a little more bold (?) and not get caught up in small things.

Perhaps because it was a short weasel hair brush, the composition of the characters was coherent, but the lines were uniform and lacked emotion. I realized the importance of trying out various brushes, ink, and paper to make the right choices.
