At the recommendation of a friend, I do zazen every Sunday.　
It's been about half a year.　The start is from 7:30.　
I went to bed early on Saturday night the day before to participate in zazen on Sunday morning.　
Also, Sunday mornings have become very productive.
In the past, I have often slept in on Sunday mornings.　
Time always moves quickly in the morning, but after zazen, it seems to move more slowly.
Why is that? It is very strange.
Perhaps my sense of time has been differently affected by zazen.
During zazen, I try not to think about anything, but in fact, many thoughts come to mind, and before I know it, I hear the signal for the end.
The passage of time feels different than normal.
What is time?
It made me think about time.
And I found it fascinating!
