Have you ever seen the wind?
Swaying trees, tearing sails, fluttering flags - this is what the wind does.
You can also determine the speed and strength of the wind by instruments.
And the wind itself?
Here is the soul ... Has anyone seen it?
But what the soul does to a person is understandable.
But to measure ...
And since they are like soul and wind, we measure the wind.
