Etymology of the word “calm”; late Latin, cauma, heat of the mid-day sun.
From Greek kauma meaning heat, from kaiein, to burn. (See caustic)
Free from agitation or passion.

It was explained that during the heat of the day the people rested because it was too hot and they would be burned from the sun.
They could do no work and had no passion to achieve anything, they were sluggish!

WE NEED PASSION! We do not need “calm”!
