When it comes to ‘the brain,’ even if it is still,
it thinks about what you did in your everyday life
and gets caught up in worthless thoughts.
Also, it spends time worthlessly by imagining things that you have not done
and following the train of thoughts continuously.
The same is true with ‘the body’ which is a magnification of the brain.
If it sits still, it will only have worthless time.
Therefore, you must do the things you must do, whatever it may be.
